I had the need to give a user the ability to load an excel document into SAP.  I wanted to build a generic load option to allow importing any excel document and building a corresponding dynamic context node and dynamic table.  I created a generic method so this can be used from any ABAP WD application. Create a reference attribute on the view as follows: 

 Add a transparent container "TBL_CONTAINER" on your view layout where you wish the table to be displayed.  Then add the following code:

 

 Prepare a test Excel Doc:

 Create a File Load:

 Test Output:
