• What is the cause and solution for SAP error message /SAPAPO/ATP179 - Direct production necessary for subcontracting (but TPOP is not active) ?

  The SAP error message /SAPAPO/ATP179 indicates that direct production is necessary for subcontracting, but the relevant configuration (TPOP - Transfer of Production Orders) is not active. This error typically arises in the context of Advanced Planning and Optimization (APO) when dealing with subcontracting scenarios.
  Cause:
  
  Subcontracting Requirement: The system has determined that a production order needs to be created for a subcontracting process, but the necessary settings to allow for this are not enabled.
  TPOP Not Active: The Transfer of Production Orders (TPOP) functionality is not activated in the system. This means that the system cannot create production orders directly for subcontracting.
  
  Solution:
  To resolve this error, you need to activate the TPOP functionality in your SAP system. Here are the steps to do this:
  
  
  Activate TPOP:
  
  Go to the SAP Easy Access screen.
  Navigate to the following path: SAP APO -> Global Settings -> Activate/Deactivate Functions.
  Look for the option related to "Transfer of Production Orders" (TPOP) and ensure it is activated.
  
  
  
  Check Configuration:
  
  Ensure that the necessary configuration for subcontracting is correctly set up in both SAP APO and SAP ERP (if applicable).
  Verify that the relevant materials and vendors are correctly defined for subcontracting.
  
  
  
  Review Master Data:
  
  Check the material master data for the items involved in the subcontracting process to ensure that they are set up correctly.
  Ensure that the appropriate procurement type is set for the materials.
  
  
  
  Test the Configuration:
  
  After activating TPOP, perform a test to see if the error persists. Create a new order or run the planning process again to verify that the issue is resolved.
  
  
  
  Related Information:
  
  Documentation: Refer to SAP Help documentation for detailed information on configuring subcontracting and TPOP.
  Transaction Codes: Familiarize yourself with relevant transaction codes such as /SAPAPO/MC90 (for planning book settings) and /SAPAPO/SDP94 (for demand planning).
  Support: If the issue persists after following the above steps, consider reaching out to your SAP support team or consulting with an SAP expert for further assistance.
