• What is the cause and solution for SAP error message FRMLDLG428 - Formula only contains secondary outputs and no primary output ?

  The SAP error message FRMLDLG428 indicates that a formula in the SAP system is defined in such a way that it only produces secondary outputs and does not have a primary output. This can occur in various contexts, such as in the formulation of products in SAP's Product Lifecycle Management (PLM) or in the context of production planning.
  Cause:
  
  Formula Definition: The formula is defined to only yield secondary outputs (like by-products or co-products) without a primary output (the main product).
  Incorrect Configuration: The formula might have been incorrectly configured, leading to the absence of a primary output.
  Data Entry Error: There may have been an error during the data entry process, where the primary output was not specified or was inadvertently omitted.
  
  Solution:
  
  
  Check Formula Configuration:
  
  Go to the formula configuration in the relevant module (e.g., Recipe Management).
  Ensure that at least one primary output is defined in the formula. This is typically the main product that you want to produce.
  
  
  
  Modify the Formula:
  
  If the formula is intended to produce a primary output, modify it to include the necessary primary output.
  If the formula is correct as it is (i.e., it should only produce secondary outputs), you may need to adjust the context in which it is being used.
  
  
  
  Review Related Master Data:
  
  Check the master data associated with the formula, such as material master records, to ensure that they are correctly set up to reflect the intended outputs.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or help resources related to formula management to understand the requirements for primary and secondary outputs.
  
  
  
  Testing:
  
  After making changes, test the formula to ensure that it now processes correctly without generating the error.
  
  
  
  Related Information:
  
  Primary Output: This is the main product that is produced from a formula. It is typically the focus of production and inventory management.
  Secondary Outputs: These are by-products or co-products that may be produced alongside the primary output but are not the main focus of the production process.
  SAP Modules: This error can occur in various SAP modules, including SAP PLM, SAP ERP, and SAP S/4HANA, particularly in areas related to production planning and recipe management.
  
  If the issue persists after following these steps, it may be beneficial to consult with an SAP expert or support team for further assistance.
