Symptom
When creating a Replication Flow in SAP Datasphere with an external target system, the option to change Data Types in the Mapping tab of the Projections dialog is disabled when the target table is managed externally and already exists outside of SAP Datasphere.
Environment
SAP Datasphere
Reproducing the Issue
- Create a Replication Flow in SAP Datasphere
- In "Object Properties", add a Projection
- Click on "Mapping"
- Observe that the option to change the Data Type is disabled.
Cause
This behavior is consistent with the standard functionality of SAP Datasphere. When the target table already exists outside of SAP Datasphere, the table structure is managed externally, and the system does not allow modifications to Data Types directly within the Replication Flow Mapping.
Resolution
The target table must be modified directly in the target system. Ensure the data types are adjusted there to match the Replication Flow mapping before deployment.
