• What is the cause and solution for SAP error message CU863 - Sales order not allowed if no BOM explosion ?

  The SAP error message CU863 ("Sales order not allowed if no BOM explosion") typically occurs in the context of production planning and sales order processing. This error indicates that a sales order cannot be processed because the system expects a Bill of Materials (BOM) explosion to occur, but it has not.
  Cause:
  
  Missing BOM: The sales order item is linked to a material that does not have a BOM defined in the system.
  Configuration Issues: The material may be configured in such a way that it requires a BOM explosion for sales order processing, but the necessary settings are not in place.
  Material Type: The material type may not be set up to allow sales orders without a BOM explosion.
  Production Type: The production type for the material may require a BOM explosion for sales order processing.
  
  Solution:
  
  
  Check BOM Configuration:
  
  Ensure that a BOM exists for the material in question. You can do this by navigating to the BOM transaction (CS01, CS02, CS03) and checking if a BOM is defined for the relevant material and plant.
  
  
  
  Create or Update BOM:
  
  If a BOM does not exist, create one using transaction CS01. If it exists but is not correctly configured, you may need to update it using CS02.
  
  
  
  Review Material Master Settings:
  
  Check the material master record (MM02) for the relevant material. Ensure that the material type and other settings are correctly configured to allow sales orders without requiring a BOM explosion.
  
  
  
  Check Sales Order Configuration:
  
  Review the sales order configuration in the system to ensure that it allows for the processing of sales orders without BOM explosion if that is the intended behavior.
  
  
  
  Consult with Production Planning Team:
  
  If you are unsure about the configuration or the need for a BOM, consult with your production planning or materials management team to understand the requirements for the specific material.
  
  
  
  System Settings:
  
  If the issue persists, it may be necessary to check the system settings or consult with your SAP Basis or technical team to ensure that there are no underlying issues affecting BOM processing.
