• What is the cause and solution for SAP error message /SAPAPO/SNPOPT157 - PPM/PDS &1 is using more than 1 resource for lot size planning ?

  The SAP error message /SAPAPO/SNPOPT157 indicates that a Production Planning Model (PPM) or a Product Data Structure (PDS) is configured to use more than one resource for lot size planning. This can lead to inconsistencies or complications in the planning process, as the system expects a single resource to be used for lot size calculations.
  Cause:
  
  Multiple Resources Defined: The PPM or PDS has been set up with multiple resources for the same operation, which is not allowed for lot size planning.
  Configuration Issues: The configuration of the PPM or PDS may not align with the requirements for lot size planning, leading to this error.
  Resource Assignment: The resources assigned to the operation may not be properly defined or may overlap in a way that confuses the planning logic.
  
  Solution:
  
  
  Review Resource Assignment:
  
  Go to the PPM or PDS in question and check the resource assignments.
  Ensure that only one resource is assigned for the lot size planning operation.
  
  
  
  Modify PPM/PDS:
  
  If multiple resources are necessary for production, consider creating separate operations for each resource instead of assigning them to the same operation.
  Adjust the PPM or PDS to ensure that it complies with the requirement of having a single resource for lot size planning.
  
  
  
  Check Lot Size Settings:
  
  Review the lot size settings in the PPM or PDS to ensure they are correctly configured.
  Make sure that the lot size strategy aligns with the resource configuration.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or help resources for specific guidelines on configuring PPMs and PDSs for lot size planning.
  
  
  
  Testing:
  
  After making changes, run a test planning run to ensure that the error is resolved and that the planning behaves as expected.
