Hello,
The prblem comes from the table RSBASIDOC where on the production system there is an entry where the Sending system and the reaciving system is the production system.The BDLS on the PreProduction System did not manage to convert the Logical system properly.
So we modify the table RSBASIDOC manually from the database level and then we modified manually the entries in tha transaction WE20 and after that we launch the Programs : RSDG_TRFN_ACTIVATE and RSBKDTPREPAIR
Best Regards
