Debugging CDS Table Functions
So far, you could debug ABAP Managed Database Procedures (AMDPs). From now on, you can now also debug CDS table functions using the AMDP debugger.
A table function consists of a CDS definition and a SQL Script procedure implementation that is used for data retrieval when the table function is accessed (for example using OpenSQL).
