CRM BP to IS-U BP/R3 SD Replication Stopped Working

Hi all,

Here is the scenario -- we were able to get business partner replication to work from CRM to R/3 SD Customer AND IS-U BP. However, at some point this stopped working. My guess is that it happened after we did a "generation of industry-specific objects" (we thought this would fix some of the other issues we were having with other replication). This generation was the first one after the system was recently patched. Could this be the reason?

One thing to note is that we were getting some BDoc errors prior to the object generation. However, even though we did get errors (for BUPA_MAIN), the business partners were still being replicated.

Thanks in advance. Points will be awarded to helpful answers.
