Creating test data for a meaningful ABAP unit test can be challenging. The data preview in the ABAP Development Tools (ADT) for Eclipse can help with that for database tables or views. Let’s take table T100 (ABAP messages) as an example. First open the table definition and then click on the F8 button to trigger the data preview. ABAP Data Explorer in Eclipse When you right click within the Data Preview area, you get the context menu option: ‘Copy all rows as ABAP value statement’. If you don’t see this option, your ABAP Development Tools in Eclipse version might be outdated. Choosing this options copies an ABAP VALUE # statement to the clipboard. This generated statement is used to populate an internal table with the structure of table T100. Now you can add this statement into your unit test class, or here simply into a notepad application: VALUE # statement in notepad This is great for database tables but often times you might also need the content of an internal table as an input for a method or function call. To achieve this, we will create a little debugger script that can capture the content of an arbitrary internal table as a VALUE # statement. First, create the following structure in the ABAP dictionary: SE11 view of structure ZDEBUGGER_SCRIPTING_S Or simply copy and paste the following structure definition in the ADT structure editor: @EndUserText.label : 'Fields for Use in Debugger Scripts' @AbapCatalog.enhancement.category : #EXTENSIBLE_CHARACTER_NUMERIC define structure zdebugger_scripting_s { itab : ortabname; itab_from : fsline; itab_to : feline; all_table_fields : xfeld; } Next, go to transaction SAS to create the debugger script. Replace the coding in the editor with the following code: *---------------------------------------------------------------------* * CLASS lcl_debugger_script DEFINITION *---------------------------------------------------------------------* * *---------------------------------------------------------------------* CLASS lcl_debugger_script DEFINITION INHERITING FROM cl_tpda_script_class_super .

"lcl_debugger_script IMPLEMENTATION​ Save the debugger script under a new name: Save Debugger Script Make sure that the ‘Trigger’ for the script is set to ‘Execute Directly’. Let’s test the script with a little sample program: REPORT z_test_value_pound_script. START-OF-SELECTION. DATA lt_t100 TYPE TABLE OF t100. SELECT FROM t100 FIELDS * WHERE sprsl = @sy-langu ORDER BY arbgb, msgnr INTO TABLE @lt_t100 UP TO 1000 ROWS. BREAK-POINT. Execute the report. Test report with data loaded from table T100 Switch to the ‘Script’ tab and load the newly created script: Load Script ZRSTPDA_SCRIPT_VALUE_POUND Start the script: Start Script The script will send a pop up window where you can specify the internal table name, here LT_T100, whether you want to use all of the fields from the table (Use all table fields = ‘X’ ) and which rows from the internal table you want to use. Editor display of generated VALUE # statement Now you can copy and paste the generated statement into your unit test class. If you don’t need all the fields from the table, then deselect the ‘Use all table fields’ indicator. Do not want all the table fields and only 5 rows In this case you get an extra pop up to select, which fields from the table you actually want: Field Selection And here the result: Restricted Result Set The script should work fine for internal tables with a flat structure. I haven’t tested it with deep, nested structures. In SAP S/4HANA on premise release 2022 this debugger script will be delivered under the name RSTPDA_SCRIPT_VALUE_POUND. Example of test data in a unit test class generated with this script: Generated data used in a test class method Have fun generating test data for your unit tests with this little tool.
