How to cast calculation field in ABAP-CDS to a data element?

[rajkumarnarasimman]

Hi.

Instead of abap.dec(11,2), did you tried with data element name.

What is the version you are using? It looks from release ABAP 750, the data element can be specified in CAST Expression, please check here

I tried to use data element without success.

I'm using ABAP 740 SP08.

Hi

That's not possible at the moment, maybe SAP will use an annotation (eg @EndUserText.label) also in all backend tools...

 @EndUserText.label: 'A Sum'
 cast( 100 * 22 as abap.dec(11,2) ) as total,

You can already use the annotations in you custom code, if needed - tables DDHEADANNO and DDFIELDANNO or class CL_DD_DDL_ANNOTATION_SERVICE (not available with 740!)

And it's also recommended not to use the generated DDL SQL View.

I tried the annotation "@EndUserText.label" and it doesnt affect the description of the field =\

Hi

Yes, it's not yet implemented in backend now! - SAP use them eg. in CDS based GW services, but not in DDIC/DDIC related tools...
