Hi there!
Try migrate BC from 17 to 18, and when test standard API Items V2.0 (default Microsoft API) found an stange behavior of templates.
If do post with baseUnitOfMeasureCode templates don`t work.
Test querry like:
{
"displayName": "testtest",
"baseUnitOfMeasureCode": "BOX"
}
If do querry without baseUnitOfMeasureCode API Setup templates works fine.
Try test with own database and also try demo Cronos Database with default templates and API - same resault.
In BC v17 all works fine, but v18 don`t (try v18.3 and v18.6).
Why when post baseUnitOfMeasureCode via API Setup tamplets stop work?
How to fix that?
