The SAP error message UPO_MIG183 indicates that there is an issue related to the migration of tank data in the system. Specifically, it suggests that a tank with the same identifier already exists in the specified Unit of Measure (UOM) and has not been modified during the migration process. This can occur during data migration activities, such as when using the SAP Migration Cockpit or other data transfer tools.
Cause: Duplicate Entry: The tank you are trying to migrate already exists in the system with the same identifier and UOM. No Changes Detected: The migration process is designed to only update or create records that have changes. If the system detects that the tank's data has not changed, it will raise this error. Data Integrity Issues: There may be issues with the data being migrated, such as incorrect mappings or configurations that lead to duplicate entries.
Solution: Check Existing Data: Verify if the tank already exists
