From what I know, when you download the adapter object there are suppose to be business partners created with a role of BBP003. Also these plants are suppose to be added to the CRM plant table (CRMM_LOCMAP).
Now here is my issue:
I noticed that there were some plants in ECC (T001W) that were not in CRM (CRMM_LOCMAP), so I downloaded the adapter object DNL_PLANT (no filters set). Assuming that this would do everything correctly, but it has not. No new plants were added to CRMM_LOCMAP. BPs were created for all of the plants in the table T001W but they do not have the BBP003 role.
Let me know if anyone has experienced similar issues.
