Resolution

S.No Object Cause Resolution/Workaround Additional Info
1 Service Request / Tickets

If HeaderObjectId and ParentObjectId are removed from the export file, then this leads to data records being sent in parallel and to a locking issue.

 Ensure that you don't remove HeaderObjectId and ParentObjectId and only update the column value that needs to be updated.
2 Account Contact Persons

You try to assign the same contact ABC to a list of multiple accounts.

As this is a rather seldom use case, the service is optimized to import account contact relationships grouped by account, and to perform changes for different accounts in parallel sessions.

This optimizes throughput - many more customers have multiple contacts assigned to one account, instead of having the same contact assigned to multiple accounts.

Unfortunately there is no flexibel way to control the way of processing, based on data provided in an input file.

 To import account contact relationships, you can use service BusinessPartnerRelationship as this service does not use parallel sessions.

Account Contact Persons is a sub-entity in customer service.

For sub entities, the records group them on parentID (parent External key or parent internal ID).
