Deploy initial data from CSV on a field with @readonly annotation

Tesnimk — Thu, 07 May 2026 12:53:32 GMT

Hi CAP community,

I am trying to update our CDS model by using @readonly annotation for one of our fields.

Based on provided documentation Declarative Constraints | capire , I've understood that this will permit to ignore the field value on both Create and Update operation.

My question here is: will this impact deploying initial data for that field for that field using CSV file ? should I expect a regeneration of this table artifact with a different column definition when using @readonly annotation?

BR,

Tesnim

Hello

@readonly does NOT change DB table structure
It only prevents write (create/update) via service

@readonly is service-level restriction only, no DB or deployment impact.

Thanks,
Sravan
