XML Loader Configuration Error

[former_member643271]

Hello,
I am using a transaction in SAP MII (v12.1.9.108) to list PM Notifications which works fine when executed. The issue I have is generating sample data. When I first open the transaction in the workbench, it is possible to view the available response fields for the BAPI (BAPI_ALM_NOTIF_GET_DETAIL)....

However, when I right click on the function block for this BAPI and select 'Generate Sample' I get a blank error message with heading 'XML Loader Configuration' and the response fields disappear....

Please can anyone suggest what the cause is or a way to resolve this issue?
Many thanks.
