• What is the cause and solution for SAP error message WM387 - Material & does not have any components ?

  The SAP error message WM387 ("Material & does not have any components") typically occurs in the Warehouse Management (WM) module when you attempt to perform an operation (like picking, transferring, or putting away) for a material that is expected to have components or sub-items, but none are defined in the system.
  Cause:
  
  Missing BOM (Bill of Materials): The material in question may not have a BOM defined, which means that it does not have any components associated with it.
  Incorrect Material Type: The material type may not be set up to allow for components or may not be configured correctly in the system.
  Configuration Issues: There may be issues with the configuration of the material master or the warehouse management settings.
  Data Inconsistencies: There could be inconsistencies in the data, such as missing or incorrect entries in the material master or BOM.
  
  Solution:
  
  
  Check BOM: Verify if a BOM exists for the material. You can do this by using transaction code CS03 (Display BOM) to check if the material has a BOM defined.
  
  If there is no BOM, you may need to create one using transaction code CS01 (Create BOM).
  
  
  
  Material Master Review: Check the material master data using transaction code MM03 (Display Material) to ensure that the material is set up correctly and that it is of the correct type that allows for components.
  
  Ensure that the material type is appropriate for the intended use (e.g., finished goods, semi-finished goods).
  
  
  
  Configuration Check: Review the configuration settings in the Warehouse Management module to ensure that they are set up correctly for the materials you are working with.
  
  This may involve checking the settings in SPRO (Customizing) related to WM and material management.
  
  
  
  Data Consistency: Run consistency checks to ensure that there are no data inconsistencies in the material master or BOM. This can sometimes be done through standard SAP reports or tools.
  
  
  Consult Documentation: If the issue persists, consult SAP documentation or reach out to your SAP support team for further assistance.
