Possible Reasons why Invoice is Disassociated with a Sales Order

Reasons for disassociation of invoice to sales order:

1. Customer name was changed in the Invoice record

2. All line Items pre-populated from the Sales order are deleted

   ---Manually re-entering same items that are present on the Sales order still deletes the link to Sales Order

   ---The form will show> Created From: Sales Order #SOxxxx before saving but after saving the form, the value of Created From field will be deleted

   ---A new Revenue Arrangement will be created. In effect, there will be a Revenue Arrangement for both Sales Order and Invoice.

3. Project field of all line Items that were pre-populated from the Sales Order are changed on the Invoice
