• What is the cause and solution for SAP error message /SAPAPO/OM_ERROR2344 - Extern. constraints must not be adhered to more strictly than inter. ones ?

  The SAP error message /SAPAPO/OM_ERROR2344 indicates that there is a conflict between external constraints and internal constraints in the Advanced Planning and Optimization (APO) module. Specifically, it suggests that the external constraints (which may come from suppliers, customers, or other external sources) are being adhered to more strictly than the internal constraints (which are defined within the system for production, inventory, etc.). This can lead to infeasibility in the planning process.
  Cause:
  
  Constraint Configuration: The external constraints are set up in such a way that they are more restrictive than the internal constraints. This can happen if the external demand or supply conditions are not aligned with the internal planning parameters.
  Data Inconsistency: There may be inconsistencies in the data being used for planning, such as incorrect lead times, lot sizes, or capacity constraints.
  Planning Version Issues: The planning version being used may not be correctly configured to handle the constraints appropriately.
  Master Data Issues: Problems with master data, such as incorrect product or resource definitions, can also lead to this error.
  
  Solution:
  
  Review Constraints: Check the configuration of both external and internal constraints. Ensure that the external constraints are not set to be more stringent than the internal ones.
  Adjust Planning Parameters: Modify the planning parameters to ensure that they are aligned. This may involve adjusting lead times, lot sizes, or capacity settings.
  Data Validation: Validate the master data and planning data to ensure that there are no inconsistencies. This includes checking product master data, resource master data, and any relevant planning data.
  Planning Version Check: Ensure that the correct planning version is being used and that it is configured properly to handle the constraints.
  Consult Documentation: Refer to SAP documentation or notes related to this error message for any specific recommendations or patches that may address the issue.
  Testing: After making adjustments, run a test planning run to see if the error persists. Monitor the results to ensure that the changes have resolved the issue.
