Overview

Every customer does their data maintenance in Excel and most of the SAP implementation or Support projects would get a requirement to upload an excel file into SAP system either to store the data in data dictionary or for reporting – Predominantly to display the excel data in ALV/ in table control (in both SAP GUI and Webdynpro).

Most of our SAP ABAP consultants would have thought about this business scenario and posted a lot of threads in SCN too ;). I see a lot of SCN responses recommends the consultants to convert excel (XLS) file to Tab Limited File or Comma Separated File (CSV) and to use GUI_UPLOAD for uploading the data into internal table. Most of the threads on this subject are left unanswered.

Besides, each ABAP consultants would have tried uploading the data using the following renowned function modules and somehow managed to complete the requirement. Have a gaze at the disadvantages in the classical approach in the following tabular representation,

Function Module Disadvantages

GUI_UPLOAD Does not handle the excel file. Excel file needs to be converted to Tab Limited or Comma Separated file. – The accuracy of the data and validating is pretty challenging

TEXT_CONVERT_XLS_TO_SAP Data processing is very slow and mass data upload is not optimistic.

ALSM_EXCEL_TO_INTERNAL_TABLE Data processing is very slow as it processes the data cell by cell and the count of rows and columns are fixed. KCD_EXCEL_OLE_TO_INT_CONVERT

Table 1: This table illustrates the conventional SE37 function modules available to upload the excel file into our

application server.

In addition, the last three function modules are available as part of “SAP_APPL” component and hence those are available only for logistics and accounting modules. The chances of using this three function module in other modules like Solution Manager or CRM or SRM systems are not possible owing to their unavailability. Furthermore, all the above Function Modules cannot be used in Webdynpro ABAP.

Beyond SAP’s technical difficulties, Microsoft excel has its own restrictions as the total number of rows is limited to 65,536 and the XLS format is stored in Binary format. Owing to all this complexities, until NetWeaver 7.0, SAP does not offer any standard way to upload Microsoft’s proprietary excel.

As of NW 7.02 (NetWeaver 7.0 Enhancement Package 2), SAP does support the excel operations (Import/ Export) due to the openness of excel since Microsoft office 2007. Click here to know the difference between XLS and XLSX files.

Openness of Excel (XLSX Format)

XLSX is a default Excel 2007 workbook format. In reality, the XLSX document is a ZIP compressed archive with a directory structure of XML text documents. As shown in the screenshot below, the XLSX file could be extracted and the excel data are place in the following file path.

The following are an important XML files, we need to refer to fetch the data from ABAP,

1. Sheet Data – SPFLI\xl\sheet1.xml

2. Shared String – SPFLI\sharedStrings.xml

Have a look at the pictorial representation of the folder structure,

Figure 1: The screenshot depicts the following activities, 1. Decompress/ extract the XLSX file

2. Folder Structure of XLSX 3. XML files where we could find the excel data



© 2012 SAP AG 5

Each excel sheet and its cells are parsed as an XML document. Every strings in excel are uniquely stored in a separate XML document “sharedstrings.xml” and those indexes are maintained in the respective sheet XMLs whereas the integer values are maintained in the sheet XML itself. Have a glimpse of it in the following screenshots,

Figure 2: The topmost view illustrates the schema of sheet XML and shared string XML and the how the mapping takes

place. The lower view is a snapshot captured from the excel file.

Thus, the effort of reading excel is much simplified and now all we need to do is to read multiple XML files from XLSX package to populate an internal table.

APIs for Office Applications

As of NetWeaver 7 Ehp2 (7.02), we have a different APIs to adapt to the openness of MS Office platform. The following classes are as part of those,

CL_XLSX_DOCUMENT Loads/ creates an XLSX document. This is the API we use in this document to load the excel file into ABAP internal table.

CL_DOCX_DOCUMENT Loads/ creates an word document

CL_PPTX_DOCUMENT Loads/ creates presentations.

Table 2: Classes for reading office applications (Excel, document and power point)

XLSX Import – How to

The following are the steps ought to be followed to upload the file into ABAP Internal Table, here you go…

1. Read the path of the uploaded file by offering a “File open dialog”

2. Load the content of the file

3. Load the package

4. Load the parts of the package

5. Load the Shared String XML and Sheet1 XML

6. Process the XMLs using XSL transformation

The aforesaid steps are applicable for Webdynpro ABAP too by having “Upload UI element” in place.

Step 1 – Read the path of uploaded file

Get the file open dialog (on hitting F1) using the static method browse_local_file_open from the class cl_openxml_helper as shown in the following code snippet,

AT SELECTION-SCREEN ON VALUE-REQUEST FOR filename.

cl_openxml_helper=>browse_local_file_open(

iv_title = 'Select XLSX File'

iv_filename = ''

iv_extpattern = 'All files(*.*)|*.*' ).

This method gets you the path of the selected file in the string variable. You could achieve this using the static method file_open_dialog in the class cl_gui_frontend_services,


CALL METHOD cl_gui_frontend_services=>file_open_dialog

EXPORTING window_title = 'Select XLSX File'

initial_directory = dir

file_filter = '*.xlsx'

multiselection = ''

CHANGING file_table = filetable

rc = i.

IF i = 1.

READ TABLE filetable INDEX 1 INTO ft.

srcpath = ft-filename.

ENDIF.

Step 2 – Load the file content

Initially, the content of the selected file path should be uploaded into our program using the static method load_local_file( ) from the class cl_openxml_helper,

TRY.

mv_file_data = cl_openxml_helper=>load_local_file( lv_filename ).

CATCH cx_openxml_not_found.

ENDTRY.

This will get you a hexadecimal content. This could be also achieved using the removed GUI class, so called cl_gui_frontend_services=>fui_upload. As this frontend classes is usable only in SAP GUI based transactions (not for webdynpro), we use the XML helper class cl_openxml_helper, which could be used both in SAP GUI programs and webdynpro applications.

Step 3 – Loading the Package

As I mentioned before, the entire XSLX file is wrapped up in a compressed package and which is not readable unless we read the package. For loading the package, we have a class cl_xlsx_document which has got unveiled since NW 702 (NetWeaver 7 Ehp 2).

TRY.

mo_package = cl_xlsx_document=>load_document( iv_data = mv_file_data ).

CATCH cx_openxml_format cx_openxml_not_found.

ENDTRY.

Step 4 – Loading the parts of the Package

The loaded package will be in the format shown below and for reading the data from excel sheet1 we need to read the XML “sharedString.xml” from “XLSX\SPFLI\xl” and “sheet1.xml” from “XLSX\SPFLI\xl\worksheets” folder. As these files are present in the different folders; we need to differentiate and identify the XML by means of package parts.

Figure 3: The above screenshot refers to the different folder paths where user could locate the required XMLs to

populate the excel rows and columns.

The following code snippet would let you locate the exact XML file.

TRY.

mo_parts = mo_package->get_parts( ).


ENDTRY.

Step 5 – Load the XMLs

We need to read “Sheet” and “Shared String” XML files which are wrapped up in the loaded package. These files could be located using the part reference (refer step 4).

Read the “Sheet1 XML” by passing to the part number as “2” as shown in the code snippet below. (load_xml_data is the method you could find in the example program)

CONSTANTS co_sheet_xml TYPE i VALUE 2.

DATA mv_sheet_data TYPE xstring.

mv_sheet_data = load_xml_data( co_sheet_xml ).



© 2012 SAP AG 8

Read the “Shared String XML” by passing to the part number as “3”,

CONSTANTS co_shared_str_xml TYPE i VALUE 3.

DATA mv_shared_data TYPE xstring.

mv_shared_data = load_xml_data( co_shared_str_xml ).

Method Implementation:

METHOD load_xml_data.

DATA lo_xml_part TYPE REF TO cl_openxml_part.

DATA lo_xml_part_uri TYPE REF TO cl_openxml_parturi.

DATA lv_uri TYPE string.

TRY.

lv_uri = mo_parts->get_part( 2 )->get_parts( )->get_part(

iv_xml_index )->get_uri( )->get_uri( ).

lo_xml_part_uri = cl_openxml_parturi=>create_from_partname( lv_uri ).

lo_xml_part = mo_package->get_part_by_uri( lo_xml_part_uri ).

rv_xml_data = lo_xml_part->get_data( ).


ENDTRY.

ENDMETHOD.

Step 6 – Process the XML – Less ABAP – More XSLT

XSLT: XSL stands for EXtensible Stylesheet Language, and is a style sheet language for XML documents driven by W3C. XSLT stands for XSL Transformations. XSLT is a language for transforming XML documents into other XML documents or other objects such as HTML, XML or XSL. Typically, input documents are XML files, but anything from which the processor can build an XQuery and XPath Data Model can be used. The original document is not changed; rather, a new document is created based on the content of an existing one. XSLT is a Turing-complete language, meaning it can perform any calculation that can be performed by a modern computer program.

For more information for XSLT refer http://www.w3schools.com/xsl/

XSLT in ABAP: The SAP XSLT processor is already available as part of the kernel since Basis release 6.10 with the specifications defined for the XSLT version 1.0. XSLT has a capability to transform the following,

XML to XML

XML to ABAP Internal Table

ABAP Internal Tale to XML

ABAP Internal Table to ABAP Internal Table

Click here to know more about ABAP XSLT Programming and gaze at the examples too.

To create XSLT Programs in ABAP go to TCode SE80 Right Click on the Package Create Other (1) Transformation Enter the name of the transformation and choose the type as “XSLT”.

Figure 4: Captured from SE80 transaction while attempting to create the XSLT transformation.

Processing the Sheet and Shared String XML

The processing of XSL transformation is much faster than ABAP language and hence we are going to do more XSLT and less ABAP for processing the XML data.

The XSLT will read the “sheet xml data” and map the cell indexes with the “shared string XML” to read the cell data.

In XSLT, we can pass only one XML file as a source; whereas we have two XML documents (Sheet XML and Shared String XML) which need to be desterilized to form an internal table. Hence we are going to pass the sheet XML as a source for XSLT and shared String XML as a parameter my removing the XML namespaces. For removing the namespaces we are going to create another transformation. (Our objective is to read and process both the XMLs using a single XSLT program.)

TRY.

CALL TRANSFORMATION zben_shared_string_del_namesp

SOURCE XML mv_shared_data

RESULT XML lv_shared_str_xml.

CALL TRANSFORMATION zben_xlsx_sheet_import

PARAMETERS p_shared_string = lo_shared_str_nodeset

SOURCE XML mv_sheet_data

RESULT lt_spfli = mt_spfli.

CATCH cx_xslt_exception.

ENDTRY.

The internal table mt_spfli is the final internal table needs to be passed to the ALV.

Transformation Parameters Remarks

ZBEN_SHARED_STRING_DEL_NAMESP Source Shared String XML

Result Shared String XML without namespaces

Removes the namespace of “Shared String XML”. [we are going to pass this XML as a parameter string to the main xslt as passing the XML as a parameter is forbidden]

ZBEN_XLSX_SHEET_IMPORT Source Sheet XML

Parameter Shared String XML without namespace)

Result (LT_SPFLI) ABAP Internal Table

Processes the sheet data and shared string data to populate an ABAP internal table.

Business Scenario

I have identified two scenarios one for SAP GUI and other for Webdynpro ABAP just to motivate you try out this unified approach. You could use the same transformation for both the scenarios. Refer the subsequent sections and try to make out the working scenario by referring to the code snippet showcased in the previous sections. If you find any difficulties, please go through the complete code (ABAP and XSLT in the last section)

Scenario 1 – Using SAP GUI

ALV needs to be populated by uploading the data from XLSX document.

Step 1: Choose the XLSX file in the selection screen

Figure 5: Selection Screen captured from SAP GUI with a single parameter for uploading the excel file

Step 2: On hitting F8, the uplaoded excel file needs to be processed and display the data in the ALV as shown below,

Figure 6: ALV which lists the Flight information which has been processed by our classes and transformation.

Scenario 2 – Using Webdynpro ABAP

Table needs to be loaded by uploading the data from XLSX document

Step 1: Choose the XLSX file in the upload UI element

Figure 7: Webdynpro application with a “FileUpload” UI element and an button to upload the excel file.

Step 2: Click on “Upload XLSX”, the fine needs to be processed and displayed.

Figure 8: Webdynpro “Table” UI element which shows the uploaded data from the excel file.

XLSX Source File – To Upload

I knew that creating a XLSX document from scratch would take a lot of time. If you feel so get the file from the DDIC itself in the following way,

1. Transaction Code SE16

2. Table Name: SPFLI

3. Execute

4. Upload the ALV output by exporting the data in XLSX format.
