• What is the cause and solution for SAP error message MEPO131 - Material ledger and retention cannot be used together ?

  The SAP error message MEPO131 indicates that there is a conflict between the Material Ledger and the retention of materials in the system. This error typically arises when you attempt to use both functionalities simultaneously, which is not allowed in certain configurations.
  Cause:
  The error occurs because:
  
  Material Ledger Activation: The Material Ledger is activated for the material in question, which allows for actual costing and multiple currency valuations.
  Retention Configuration: The material is also configured for retention, which is a process that allows for the temporary holding of materials in inventory without them being fully processed or accounted for.
  Incompatibility: SAP does not allow the use of both features together for the same material, leading to the MEPO131 error.
  
  Solution:
  To resolve the MEPO131 error, you can take the following steps:
  
  
  Check Material Configuration:
  
  Go to the material master record (transaction code MM03) and check the settings for the material in question.
  Ensure that the Material Ledger is either activated or deactivated based on your business requirements.
  
  
  
  Decide on Functionality:
  
  If you need to use the Material Ledger, you will need to deactivate the retention functionality for that material.
  Conversely, if retention is necessary, you may need to deactivate the Material Ledger for that material.
  
  
  
  Adjust Settings:
  
  If you decide to deactivate the Material Ledger, you can do this in the configuration settings (transaction code OML2) or through the material master record.
  If you need to deactivate retention, you may need to adjust the settings in the relevant configuration area.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or consult with your SAP support team for specific steps on how to change these settings based on your version of SAP.
  
  
  
  Testing:
  
  After making the necessary changes, perform a test transaction to ensure that the error no longer occurs.
  
  
  
  Related Information:
  
  Material Ledger: A functionality in SAP that allows for actual costing and provides detailed inventory valuation.

  Transaction Codes: Familiarize yourself with relevant transaction codes such as MM03 (Display Material), OML2 (Material Ledger Configuration), and ME21N (Create Purchase Order) to navigate through the system effectively.
  
  If the issue persists after following these steps, it may be beneficial to consult with your SAP Basis or functional team for further investigation.
