Symptom
Create a CDS view in the ABAP system on top of a table with String field of length 0 and access the CDS view in Datasphere Replication Flow as source object. The String column is not shown in the Object properties dialog in Datasphere.
Environment
SAP Datasphere
Reproducing the Issue
- Create an ABAP CDS view on top of an ABAP table with a String column of length 0
- Create a connection to the ABAP source system in Datasphere
- Create a replication flow with the ABAP CDS view as the source in Datasphere
- Check the Object properties of the source CDS and the String column is missing
Cause
String column of length 0 is an unlimited length column and is considered a Large Object(LOB) column. This is not supported by Datasphere. Check note 3223810 - Known limitations and important considerations for Replication Flows for the limitation on Large Object(LOB) columns.
Resolution
The string column of the underlying table can be a max length of 5000 to be visible in Datasphere
