Tridion 9.5 Core Service - how to fetch list of Publish purpose

Question

With the reference to this thread: https://tridion.stackexchange.com/a/4597/1556

I am looking for a similar answer where I need to fetch a list of publishing purposes(BPT) instead of PublicationTargets.

Could someone please suggest me this?

Answer 1

For Core Service, read the BPT from the Publication and then you can get to TargetTypes and their Purpose:

var pub = (PublicationData)client.Read("tcm:0-x-1", null);  
var bpt = (BusinessProcessTypeData)client.Read(pub.BusinessProcessType.IdRef, null);
bpt.TargetTypes.Select(tt => tt.Purpose);

Answer 2

A Publication/Repository has a BusinessProcessType property which tells you what the selected Business Process Type (BPT) is for that Publication/Repository (if any).

A Business Process Type contains a set of Target Types which each have a distinct Purpose.

So, if you are working with TOM.NET and want to get a list of publishing purposes for a given context Publication, your code could look like this:

contextPublication.BussinessProcessType?.TargetTypes.Select(tt => tt.Purpose);
