• What is the cause and solution for SAP error message /SAPAPO/LOM066 - More than one issuing storage location exists in stor. loc. MRP area & ?

  The SAP error message /SAPAPO/LOM066 indicates that there is an issue with the configuration of storage locations in the context of Material Requirements Planning (MRP) areas in SAP Advanced Planning and Optimization (APO). Specifically, the error states that more than one issuing storage location exists for a given storage location in the MRP area, which is not allowed.
  Cause:
  This error typically arises due to the following reasons:
  
  Multiple Issuing Storage Locations: The MRP area is configured with more than one issuing storage location for the same storage location, which violates the system's requirement for unique issuing storage locations.
  Configuration Issues: There may be incorrect or incomplete configuration in the MRP area settings, leading to ambiguity in determining which storage location should issue stock.
  Data Inconsistencies: There could be inconsistencies in the master data or configuration settings that need to be resolved.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check MRP Area Configuration:
  
  Go to the transaction code /SAPAPO/MRP_AREA or use the relevant configuration path in SAP APO.
  Review the MRP area settings to ensure that each storage location has only one issuing storage location defined.
  
  
  
  Adjust Issuing Storage Locations:
  
  If you find multiple issuing storage locations for the same storage location, you will need to adjust the configuration to ensure that only one issuing storage location is assigned.
  You can do this by editing the MRP area settings and removing the redundant issuing storage locations.
  
  
  
  Review Master Data:
  
  Check the material master data and ensure that the storage locations and MRP areas are correctly defined.
  Make sure that the relevant materials are assigned to the correct MRP areas and that the storage locations are properly configured.
  
  
  
  Test Changes:
  
  After making the necessary adjustments, test the changes by running the MRP process again to see if the error persists.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or help notes related to MRP area configuration for additional guidance and best practices.
  
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as /SAPAPO/MRP_AREA, /SAPAPO/MDP, and others that may help in managing MRP areas and storage locations.
  SAP Notes: Check for any SAP Notes that may address this specific error or provide additional insights into MRP area configuration.
  Training and Support: If you are unsure about making changes, consider reaching out to your SAP support team or consulting with an SAP expert who specializes in APO and MRP configurations.
