RE: Posting Issue with Sales Order and Inventory
The blank distribution accounts are a result of accounts not being listed in the items. When you create an item you must fill in those accounts. Most firms put a list of the accounts, including the 4 you listed, in an Item Class and assign the class to the items. The system does not pull accounts from the class but, either when you change data in the classes or create a new item, the class information is copied to the items.
Check your items to make sure the accounts are included in the accounts screen of the items.
All of this, including how to chase the source of accounts and other posting issues, can be found in our Inventory Flow and Posting manual. It is available on our web site listed below.
