System error in program CL_RSDOC_BUFFER and form GET_MAX_DOCID-01- (BRAIN-299)

[stephlef]

Dear experts,

In SAP BW 7.50 SP25, when trying to add a document store (in the runtime properties) to a query, the commenting works well in the test system.

After transporting the doc store, the related aDSO, the query and the related composite to the productive system, I get the following error in the productive system when running the query (it comes after validating the variables prompts):

System error in program CL_RSDOC_BUFFER and form GET_MAX_DOCID-01- (BRAIN-299)

I tried deleting the composite from the doc store, save, add composite again, save, transport, but it didn't work (same error).

I didn't try debugging the program. Any idea of what I should do before transporting again?
Best regards,

Stéphane
