When STO is created ,delivery is done thru SD route and then proforma billing .......
now my question is if you go to billing document line item double click on it and in item details tab , we will see sales document field AUBEL in which purchase order number will appear
I just want know how this STO number is appearing in sales document field .what is the link and how ?????
When you create delivery document you need to take STO as reference documentr.
When you create billing document you need to take delivey as reference so
>Delivery document>Billing document this is the way STO number will appear in the billing document.
I hope this will help you,
