• What is the cause and solution for SAP error message MW145 - Item without material will not be created ?

  The SAP error message MW145 ("Item without material will not be created") typically occurs when you are trying to create a document (like a purchase order, sales order, or production order) that includes an item that does not have a material number associated with it. This is common in scenarios where the system expects a material number for inventory management or accounting purposes.
  Cause:
  
  Missing Material Number: The item you are trying to create does not have a valid material number assigned to it.
  Incorrect Item Category: The item category you are using may not allow for items without a material number.
  Configuration Issues: The configuration settings in the material management module may not allow for the creation of items without a material number.
  
  Solution:
  
  Check Material Number: Ensure that the item you are trying to create has a valid material number. If it is a new material, make sure it has been created in the system.
  Review Item Category: Verify that the item category you are using is appropriate for the type of item you are trying to create. Some item categories require a material number, while others may allow for non-material items.
  Create Material Master: If the item is supposed to be a material, create the material master record using transaction code MM01.
  Adjust Configuration: If you have the necessary permissions, check the configuration settings in the material management module to ensure that the system is set up to allow for the creation of items without material numbers if that is your intention.
