Extending the ABAP CDS extractor

Hello Experts,

I have a question of extending the ABAP CDS extractor.

Requirement - Extend the ABAP CDS extractor I_GoodsMovementDocumentDEX with fields from MATDOC table. 

The view I_GoodsMovementDocumentDEX is created on I_MaterialDocumentRecord which in turn is created on MATDOC. Do we first create a extension view for I_MaterialDocumentRecord and have the required fields from MATDOC. Followed by one more extension view for I_GoodsMovementDocumentDEX to add those fields , or we directly add those fields in I_GoodsMovementDocumentDEX without extension view as it is already available in underlying view.

Is it recommended to change standard CDS view I_GoodsMovementDocumentDEX ? or we have to use the 2 separate extension view as mentioned above?

Thanks,

Vinay

seems no other way, but you are lucky, only two layers.

not sure if extractor has special way to extend.
