I have developed an SSIS ETL that Updates the owner of contacts based on certain informations using Kingsway Tool, each time i provide the OwnerID and the OwnerType.
In Development and UAT environment every thing works just fine, but in the Production environment i get the error "Systemuser with ID XXXXXX does not exist" . In fact the Guid XXXXXXX in each error line refers to a certain TeamID. I checked the ETL to many times and it looks fine to me, and it worked fine in DEV and UAT environment with a big amount of data.
What could be the problem ?
