Let me explain my scenario - my company A has recently merged with company B. Company A has one set of Terms of Payment for its customers (as it took advance payment). Company B has separate set of Terms of Payment for its customers..
After the merger, they will have common customers. The requirement is that if a sales order is created for one customer with one material from company A and another material from company B, the Terms of Payment for company A material should be separate and Terms of Payment for company B material should be different.
So, for this, first step is for all the item categories (to which these materials belong), the "Business Data" field should be ticked. Then,can you please mention in details what steps are required to have separate Terms of Payment at item level automatically (not manual change)?
