ABAP RESTful Application Programming Model
Salvation after 5+ years and variety of technological marriages, ABAP RAP is here finally. Fiori and WebAPI development can take a deep breath. This post is about common and uncommon snippets for ABAP RAP. This post is updated on regular manner.
All the snippets here denote one of the round boxes/components of the Programming Model.
At the beginning of time, we had to manually update admin fields of changes within BOPF determinations manually. Alternatively we created reusable base determination classes combined with custom Z annotations and reuse it within CDS views and generated BOPF objects freely. Now we can relax a bit more, RAP spports this out of the box, you just need to annotate your timestamp and username fields, system does the rest.
"Database table fields created_by : syuname; created_at : timestampl; last_changed_by : syuname; last_changed_at : timestampl; local_last_changed_at : timestampl;
--CDS: Data Modelling @Semantics.user.createdBy: true created_by as CreatedBy, @Semantics.systemDateTime.createdAt: true created_at as CreatedAt, @Semantics.user.lastChangedBy: true last_changed_by as LastChangedBy, @Semantics.systemDateTime.lastChangedAt: true last_changed_at as LastChangedAt, @Semantics.systemDateTime.localInstanceLastChangedAt: true local_last_changed_at as LocalLastChangedAt,
