Take fields from default table to custom


I’m working for a project and I need to take field “Sales Account” on General Posting Setup and put it on custom table to field “Id Account”.

The advice of project manager is:

How can do this?

Thanks so much and sorry for bad english

May I start by asking you you one question. Have you any idea why you are doing this and what the purpose of it is?

Because I don’t based on the description you have provided. When should this “crossing” and what else would be in the “custom table”.

But I assume you would need to update it when you post the sales invoice. Since you need the “Sales Account” then I assume you would insert this for each invoice line?
In that case you should create an event subscriber to the event triggered right after posting the invoice lines. At least if you are using extensions or version 11+.
