UNICODE PREPARATION PHASE:

Preparation

1. Make ABAP programs Unicode-enabled:

Programs: transactions UCCHECK and SCOVUCCHECK: Performed for Y* and Z* programs

1

2. Unicode Enhanced Syntax CheckThe system profile parameter abap/unicode_check=on can be used to enforce the enhanced syntax check for all objects in non-Unicode systems. The mentioned parameter should be set to the value "on" only, if all customer programs have been enabled according to transaction UCCHECK.If you have problems with regeneration of reports RK31*, RK32*, RK33* or RK34*, create a customer message under component CO-PA.

3. Pre- Conversion Correction of Table DataBefore starting the Unicode conversion you need to maintain data with value “SODI” in field PERS_GROUP in table ADRP according to the SAP Note 712619Run report UMG_ADD_PREP_STEP. This report consists of several reports which were created for maintaining corrupt or obsolete table data before a Unicode conversion.

Call transaction SE38. Enter report UMG_ADD_PREP_STEP and choose . On the next screen the included reports are displayed. Choose Background. All reports will be executed automatically in sequential order.

If you need to rerun one or more selected reports later, you can use button . Note: Do not use this option before UMG_ADD_PREP_STEPS has been run once using the background option.

We recommend that you maintain corrupt data in tables T52C5, TTDTG and in tables ADRC and ADRP, according to the SAP Notes mentioned below.Tables: T52C5; TTDTG; ADRC and ADRP tablesDocumentation: SAP Notes 679275; 794966; 673941Single Code Page: recommended

For the Unicode preparation a special handling has to be done for table T5GEFDATA, taking the substructure of the container field into account. Follow the description in SAP Note 1239557.

4. Text Language for Customer ObjectsAll LANG fields in Data Dictionary (DDIC) objects which are delivered by SAP have an attribute Text Lang. (indicator for a language field). This indicator specifies that the LANG field determines the code page of the character data in that table. Text Lang. flags are evaluated during RFC communication between Unicode and non-Unicode systems to ensure that the correct

5

character conversion is used. In Single Code Page conversions the flags are evaluated by R3trans.For more information, read SAP Note 480671. To set this DDIC attribute for customer objects, run report RADNTLANG.Transports into a system can cause the indicator to be overwritten. It is therefore necessary to (re)run RADNTLANG directly before beginning the Unicode preconversion in order to actualize the flags. After you have run RADNTLANG please read SAP Note 672835 carefully. You will find information about how to maintain special tables which could be affected by wrong data conversion after the Text lang. flag has been set.Text lang. flag maintenance must be finished before the Unicode Preconversion Phase. If you do any changes as described in this section after or between the SPUMG scans, you must reset the changed tables and rerun the scan(s)

5. Consistency Check for the ABAP DictionarySAP recommends running report RUTCHKNT prior to the SPUMG scans to check and clean up inconsistencies between DDIC objects and runtime objects.In transaction SE38 enter report RUTCHKNT and choose . On the following screen checkbox Check against inactive nametab must be deselected! Press

again to access the next screen.

Go to section Obj. types for checking. Select checkboxTables.Go to section Select Objects by name, field table category. Select and choose tabstrip Exclude Single Values. Select Multiple selection. Select table categories “INTTAB” (Structure) and “VIEW” (General View Structure). Choose

and then . Afterwards execute the report.Afterwards check all log messages ("Check activation of object was successful" must be checked too!). Check DDIC objects in transaction se11 (Utilities → Runtime Object → Check) and activate them.

6. Consistency Check for Cluster TablesSAP recommends checking inconsistencies in cluster tables prior to the SPUMG preparation steps. Programs: report UMG_R3CHECK_FILES; program R3checkDocumentation: SAP Note 89384Single Code Page: recommended.Run report UMG_R3CHECK_FILES in transaction SE38 order to create control files for R3check. Read the report documentation for details. Run R3check on database level as described in SAP Note 89384.

10

7. Translation EnvironmentIf you are using the SAP translation environment (transaction SE63) you must export the Proposal Pool in the non-Unicode system. When the Unicode Conversion is finished, you must import the Proposal Pool into the Unicode system. Follow the instructions in SAP Note 1055820.

Unicode Preconversion Phase

Transaction SPUMGSPUMG is used to prepare the database tables of a non-Unicode system for the conversion to Unicode. All steps in the Unicode Preconversion Phase are designed to be run at system uptime (i.e. when users are logged on to the system). The system conversion is carried out by the separate tool R3load during the database export. R3load uses the results of SPUMG which are stored in the Export Control Table, the Vocabulary and the Language Lists.Tool: transaction SPUMG

Documentation: this document; SAP Note 548016;

Single Code Page: required.

1. Preconversion Analysis: SPUMG ScansDuring the Unicode Preconversion the database tables have to run through several consecutive scans which are listed below.

12

Download umgexceptions_ver_00_011.xml to c:\AstUpg\UC\umgexceptions_ver_00_011.xml and upload it

If the system code page is 1100 you should check whether the frontend code page (or SAP GUI code page) is also 1100. Run report RSCP0013 in transaction SE38 and check, if 1100 is displayed in field Character set of SAPgui. If yes, users are able to input characters which are not covered by the system code page. Such characters – for example Euro sign (€) and the trademark sign (™) - will get lost during the database conversion because they are not stored on the database. You can prevent this at least for characters in transparent tables by switching to 1160 in the SPUMG Language List.

Not necessary to change because RSCP0013 shows Character set of SAPgui = 1160:But for older versions perhaps SAPgui codepage is 1100. Therefore do change to 1160.

2. Database CheckStart SPUMG again: Press button Continue with transaction SPUMG

4. Initialize Worklist

A worklist contains all tables of a system that have to be prepared by SPUMG for theUnicode conversion. In SPUMG, the tables have to run through several scan levels, each ofwhich has its own worklist.The worklists must be generated as follows:1. Select Scanner - Initialize - Worklist (F2). Depending on the data volume theinitialization job may take several minutes. Press pushbutton . You have generatedthe worklist for the first scan (Consistency Check).This starts job UMG_PMIG_STOCK_UPDAT which takes a few minutes to finish.

5. Monitor:On each scan level the SPUMG monitor displays scan statistics and the processing status of the tables. Select pushbutton Monitor from the toolbar.Worklist Status (Consistency Check): Initialization of the CC Worklist: Display of status and total number of initialized tables.Overview number of tables: Here you get an overview of all initialized tables sorted by table types (number of transparent, cluster, and pool tablesWorklist Overview: Here you can see how many tables are currently processed on which scan level. Tables with warnings are inconsistent and therefore need to be maintained before the conversion.Tables in Process: Here you can see which tables are currently being processed by which worker jobSelect refresh button to update the monitor.To see details about running worker jobs, select pushbutton Job Overview from the toolbar.

Unicode Conversion Phase

Program: R3loadThe default conversion method is to export the entire database using R3load, create a newUnicode database, and then import the database using R3load again.

Now before you start the Import Phase backup the whole database. Once you have successfully backup the database run sapinst and uninstall SAP and Oracle Database, but don’t uninstall the Oracle software.

Then goto data drive where all the sapdata folder are created. In our case we go to G drive and delete all the SAP Data folder, then goto H, I , J drive and delete D01 folder.

Once you have deleted everything restart the system.

Login as D01adm and goto Installation Master DVD dump and start sapinst.
