With the help of GL Accounts at distributions you can know the A/c in which we book the purchase.
For single shipment, there may be multiple GL accounts (distributions).
Distributions not only shows the a/c codes but also provides the Requisition, Project, Tasks and OSP information.
Distributions links with Requistions, Project module & WIP module as well means it contains so many things , not only A/c codes.
Thanks for your clarification, i have last query regarding Distribution if you explain some more details.
On Purchase order approval, the accounting is not generated, so the impact of this Accounting will be reflecting while creating Invoice at Distribution or sth else?
I mean, as we can mention accounting as per our shipment, so while creating invoice system will get accounting from Po Distribution but have option user can amend this?
yes, after creating the invoice , user can amend the accounting gl code at invoice distributed level.
