Thanks for writing, Tony.
Here is the code in test script paynowdatact_c.g.t:
[-] type REC_DATALIST_DD_payTaxCt_c is record
[ ] REC_SilkC_ recSilkC_ //
[ ] // *** Global record for each Table ***
[-] type REC_SilkC_ is record
[ ] REAL Record //Record#,
[ ] REAL Tax //Tax,
[ ] REAL Employee //Employee,
[ ] // *** Global record containing sample data for each table ***
[ ] // *** Used when running a testcase with 'Use Sample Data from Script' checked ***
[ ] // *** End of DATA DRIVEN ASSISTANT Section ***
Your showing the DD_payTaxCt_c testcase but your testplan is calling DD_Testnow testcase. Assuming that the argument for DD_Testnow is of REC_DATALIST_DD_payTaxCt_c, is ALL_ROWS_FOR_ALL_TABLES of this type? Where is ALL_ROWS_FOR_ALL_TABLES defined in the scope of your test?
DD_Testnow and DD_payTaxCt_c are the same so your assumption is right and sorry about that. I have amended the code to read DD_Testnow.
When I created the testplan using Menu TESTPLAN and menuitem DETAIL (Or right_click Testplan detail), ALL_ROWS_FOR_ALL_TABLES is the default (and only) value for 'Test data' in the 'Test Execution' Tab.
That is the reason, the contents of the testplan looks like:
[ ] script: paynowdatact_c.g.t
[ ] ddatestcase: DD_Testnow
[ ] ddatestdata: ALL_ROWS_FOR_ALL_TABLES
Are you doing some sort of Data Driven Testing? So what I'm gathering is ALL_ROWS_FOR_ALL_TABLES is not something that was created by you? If not, you just need to replace the ALL_ROWS_FOR_ALL_TABLES with an argument of a REC_DATALIST_DD_payTaxCt_c data type.
