Invert routine for 0Doc_Date for RRI

I'm getting this message below when jumping to an R/3 report.

"Warning Selection for 0Doc_Date cannot be uniquely assigned"

The reason is as follows. Its in the delta transfer structure but not in the CCA cube and we are not going to add it.

I was informaed that a inversion routine for object 0dat_doc could resolve this issue. I've created and activated the routine but the code there is not executed before (that I can tell ) and the message is still appearing.

Any help much appreciated!
