ABAP CDS NW7.51 built-in functions in ON condition

[sascha_bauer]

Hi all,

according to the sap documentation in ABAP CDS views since NetWeaver 7.51 built-in functions can be used in WHERE and ON conditions.

Built-in functions can now be specified on the right side of a cond_expr condition of a WHERE condition, an ON condition, a filter condition, or a complex case distinction.

I'm facing an issue using the CONCAT function on the right side of an on condition is not working. I'm getting the following error message.

This function or expression ('concat') is not supported at this point

The system is running on NW 7.52

Thanks

Sascha
