  The SAP error message CM_BOMBOS013 indicates that a key field is missing in the context of a bill of materials (BOM) operation. This error typically arises when the system expects a certain key field to be present in the data being processed, but it is not found.

  Cause:
  
  Missing Key Field: The error is triggered when a required key field (like material number, plant, or BOM usage) is not provided in the transaction or data entry.
  Data Inconsistency: There may be inconsistencies in the data being processed, such as missing entries in the database or incorrect configurations.
  Configuration Issues: The system configuration for BOM management may not be set up correctly, leading to missing fields during processing.
  
  Solution:
  
  Check Input Data: Ensure that all required fields are filled in the transaction or data entry screen. Verify that the key fields expected by the system are present.
  Review BOM Configuration: Go to the BOM configuration settings in SAP and ensure that all necessary fields are defined and correctly configured.
  Data Validation: Use transaction codes like CS03 (Display BOM) or CS02 (Change BOM) to check if the BOM exists and is correctly set up. Ensure that the material and plant combinations are valid.
  Debugging: If you have access to debugging tools, you can trace the program execution to identify where the key field is being checked and why it is missing.
