• What is the cause and solution for SAP error message MMRP01223 - Fixing/ATP not possible because explosion not yet carried out (start RPM) ?

  The SAP error message MMRP01223, which states "Fixing/ATP not possible because explosion not yet carried out (start RPM)," typically occurs in the context of the SAP Advanced Planning and Optimization (APO) module, particularly when dealing with the planning and execution of production orders or requirements planning.
  Cause:
  This error generally indicates that the system is unable to perform the Available-to-Promise (ATP) check or fixing of a requirement because the explosion of the bill of materials (BOM) has not yet been executed. The explosion process is essential for determining the components required for production and their availability.
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check BOM Configuration: Ensure that the BOM for the material in question is correctly configured and active. If the BOM is not maintained or is inactive, the explosion cannot be carried out.
  
  
  Run the Explosion: Manually trigger the explosion of the BOM. This can typically be done through the following transaction codes:
  
  MD04: To check the stock/requirements list and see if the explosion has been executed.
  MD61: To create planned independent requirements if necessary.
  MD02: To run the planning run which includes the explosion of the BOM.
  
  
  
  Check Planning Parameters: Ensure that the planning parameters for the material are set correctly. This includes checking the planning strategy, lot size, and other relevant settings.
  
  
  Review the Planning Run: If you are using a planning run (like a heuristic or a detailed planning run), ensure that it has been executed successfully. You may need to check the logs for any errors that occurred during the planning run.
  
  
  Check for Dependencies: Sometimes, the error can be caused by dependencies or prerequisites that have not been met. Ensure that all necessary preceding steps in the planning process have been completed.
  
  
  Consult Documentation: If the issue persists, refer to SAP documentation or consult with your SAP support team for more specific guidance related to your system configuration.
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as MD04 (Stock/Requirements List), MD02 (Single-Item, Multi-Level Planning), and MD61 (Create Planned Independent Requirements).
  SAP Notes: Check for any SAP Notes related to this error message for additional troubleshooting steps or patches that may be applicable.
  User Roles and Authorizations: Ensure that the user executing the planning run has the necessary authorizations to perform BOM explosions and ATP checks.
  
  By following these steps, you should be able to resolve the MMRP01223 error and successfully carry out the required planning activities in SAP.
