SMQ1 "Message edited in target system"

Seeing in some of our datasources records not making it into PSA of BW from CRM. We create new transaction or edit existing in CRM. In CRM I can see the record in RSA7 and also in SMQ1. In SMQ1 the records that come into BW PSA have status “Transaction recorded” but records that dont make it into BW that should, instead have status “Message edited in target system”. What is this message? Is something being locked up in BW preventing these records from coming over?

Thank You
