  Cause:
  This error occurs when you attempt to create a dateline (delivery schedule line) in a purchasing document (such as a Purchase Order or Scheduling Agreement) without first specifying a supplier in the Purchase/Sales tab of the document header or item level.

  Enter Supplier Information:
  
  Go to the Purchase/Sales tab in the purchase document header or item.
  Enter the supplier/vendor number.
  Save the document.
