Consider we have a Fiori app build using Fiori elements/ smart controls consuming an OData service (SEGW) created using a standard ABAP CDS view. The standard ABAP CDS view already has UI annotations for all relevant fields which needs to be displayed.
How can we modify the annotation of a/ more field(s)? Can we do it in extension CDS view (i guess no) or SEGW by creating an annotation model/ redefining service with annotations?
For instance, simple example: Standard CDS has a field CompanyCode displayed at position 10, which i need to hide or move to position 50.
