Hello guys,
just to inform you, we are facing the same problem too. SAP did not provide us with a solution till now(for example fix-Report to correct the inconsistencies). Any way they gave us the following feedback:
===
Checking the data of the BP examples you provided between CRP and ERP,
the data between ERP CRMPARNR, KNVK and CRM CRMM_BUT_CONTNO, BUT050
are messed up. From SAP end, we could not provide any help on identify the cause for
this inconsistency because it is not reproducible. Besides, we don't know if there are also other contact relationships have this problem.
The cause of this issue could be the activation of CVI on ERP which synchronizes ERP
customer, vendor with ERP BP but may assign different GUID.
In addition, replications on ERP customer and ERP BP to CRM BP are enabled currently.
Under this circumstance , CRM end has no sufficient knowledge to judge if contact relationship sent from ERP is originally created by ERP customer or ERP BP because they are embedded in different MW object CUSTOMER_REL and BUPA_REL. That will introduce the inconsistency between ERP CRMPARNR and CRM CRMM_BUT_CONTNO.
This is only a hypothetical analysis for this issue.
