The entity is merged in Opendata and Veeva Network. After running a subscription in CRM, the merged loser does not get handled in CRM.
The merged loser is not exported to the target subscription file. One reason is the target subscription has the filter Valid & Under Review enabled.
The merged loser with the record state of MERGED_INTO is not exported to the target subscription zip file.
Check the target subscription output file. Confirm if the merged loser is included in the file with MERGED_INTO record state.
If it exists, check the CRM side to see if there is any subscription error.
If it does not exist, check the Network side to identify if the loser record meets any filter in the target subscription definition.
