Masterdata grouping and collection strategy not updated on CA

Hi Experts

We had an issue after upgrade the master data grouping and collection strategy were not getting updated on CA.

I updated them via a prog using BAPI_CONTRACTACCOUNT_CHANGE but some of them were still not updated with error "Contact person 1200822639 does not match grouping CA" message class: FKK_CM , message number = 070. Also to note, there are multiple CA on BP and the master data grouping and colleciton strategy doesnt match could be a reason.

But now the issue is when we are trying to put a dunning lock on the other CA with collection strategy and master data grouping of the same BP its giving this same error. Any idea how can we avoid it? Any SAP note on this.

Any help would be much appreciated. Thanks,

Regards,
