• What is the cause and solution for SAP error message CO136 - Quantity must be positive for item category & ?

  The SAP error message CO136 ("Quantity must be positive for item category &") typically occurs in the context of controlling (CO) when you are trying to post a transaction that involves a quantity that is either zero or negative for a specific item category in a controlling document, such as a production order or a cost center.
  Cause:
  
  Negative or Zero Quantity: The most common cause of this error is that the quantity being entered for a specific item category is either zero or negative. This is not allowed for certain item categories in SAP, as they require a positive quantity to process the transaction.
  Incorrect Item Category: The item category being used may not support negative quantities. For example, certain item categories are designed for goods receipt or production where a positive quantity is mandatory.
  Configuration Issues: There may be configuration settings in the system that enforce positive quantities for specific item categories.
  
  Solution:
  
  Check Quantity: Ensure that the quantity you are trying to enter is a positive number. If you are trying to reverse or adjust a quantity, make sure you are using the correct transaction type that allows for such actions.
  Review Item Category: Verify that you are using the correct item category for your transaction. If the item category does not allow for negative quantities, you may need to select a different category or adjust your transaction accordingly.
  Adjust Configuration: If you believe that the configuration should allow for negative quantities for the specific item category, you may need to consult with your SAP configuration team to review the settings in the system.
  Transaction Type: If you are trying to perform a reversal or adjustment, ensure that you are using the appropriate transaction type that allows for such actions.
