• What is the cause and solution for SAP error message MPE_OAN307 - More than one BOM item was selected for log. component &1 in operation &2 ?

  The SAP error message MPE_OAN307 indicates that more than one Bill of Materials (BOM) item has been selected for a log component in a specific operation. This typically occurs in the context of production planning or manufacturing processes where a component is expected to have a unique BOM item associated with it, but multiple items have been found.
  Cause:
  
  Multiple BOM Entries: The primary cause of this error is that there are multiple BOM entries for the same component in the specified operation. This can happen if the BOM is not properly maintained or if there are duplicate entries.
  Incorrect Configuration: The configuration of the production order or routing may not be set up correctly, leading to ambiguity in which BOM item should be used.
  Data Inconsistency: There may be inconsistencies in the master data, such as the material master or BOM data, which can lead to multiple BOM items being selected.
  
  Solution:
  
  
  Check BOM Configuration:
  
  Go to the BOM transaction (CS03) and check the BOM for the component in question. Ensure that there is only one valid BOM entry for the component in the context of the operation.
  If there are multiple BOMs, determine which one should be used and remove or deactivate the others if they are not needed.
  
  
  
  Review Production Order:
  
  Check the production order (CO02) to see how the components are assigned. Ensure that the correct BOM is being referenced in the operation.
  If necessary, reassign the correct BOM item to the operation.
  
  
  
  Data Consistency Check:
  
  Run consistency checks on the BOM and material master data to identify any discrepancies. This can often be done using transaction codes like CS15 (BOM explosion) or CS12 (BOM comparison).
  Correct any inconsistencies found during the checks.
