• What is the cause and solution for SAP error message /SAPAPO/LOM064 - More than one leading storage location exists in storage loc. MRP area & ?

  The SAP error message /SAPAPO/LOM064 indicates that there is more than one leading storage location defined for a specific storage location in the MRP area. This situation can arise in the Advanced Planning and Optimization (APO) module when the system expects only one leading storage location for a given MRP area, but finds multiple entries instead.
  Cause:
  
  Multiple Leading Storage Locations: The primary cause of this error is that the configuration for the MRP area has been set up with more than one leading storage location. In SAP APO, a leading storage location is typically the one that is used for planning purposes.
  Data Inconsistency: There may be inconsistencies in the master data or configuration settings that lead to multiple storage locations being marked as leading.
  Incorrect Configuration: The configuration of the MRP area or storage locations may not have been done correctly, leading to this error.
  
  Solution:
  
  
  Check MRP Area Configuration:
  
  Go to the transaction code /SAPAPO/MRP_AREA and check the configuration of the MRP area in question.
  Ensure that only one storage location is marked as leading. If there are multiple entries, you will need to correct this.
  
  
  
  Review Storage Location Settings:
  
  Navigate to the storage location settings in the relevant configuration area.
  Ensure that each storage location is correctly assigned and that only one is designated as leading for the MRP area.
  
  
  
  Data Cleanup:
  
  If there are multiple leading storage locations due to data entry errors, you may need to clean up the data by removing or correcting the entries.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or help resources for detailed steps on configuring MRP areas and storage locations.
  
  
  
  Testing:
