Action is not firing on save, but it works through a button

[Jane]

Hi everyone!

I am stuck and I need help.

Have anyone encountered a situation when the action is not firing on save (or in a bot), but if you fire it through the button it works.

Action is a referenced action, which is updating a number for a specific row in one table (parent), after adding a new row in another (child).

Parent table contains information about products (primary key is concatenation of product_id and process columns), and child orders for products from Products table (primary key is Order_id).

Column to which it is writing is physical. It looks like every time on save the action is rewriting the column with blank, but if I fire the action manually with the button, it is writing a correct number.

Action is added to the form, and form is using a slice (slice also has the action).

Maybe there is an issue with primary keys, but why then manually it works?
