• What is the cause and solution for SAP error message CO046 - Material & cannot be produced in-house ?

  The SAP error message CO046 ("Material & cannot be produced in-house") typically indicates that the system has determined that the specified material cannot be manufactured internally due to various reasons. Here are some common causes, potential solutions, and related information for this error:
  Causes:
  
  
  Production Type Configuration: The material may not be set up for in-house production in the material master. This could be due to the production type being set to "external procurement" only.
  
  
  Routing Issues: There may be no valid routing defined for the material, which is necessary for production planning and execution.
  
  
  Bill of Materials (BOM): The material may not have a valid BOM, which is required to define the components needed for production.
  
  
  Plant Settings: The plant settings may not allow for in-house production for that specific material.
  
  
  Material Status: The material may have a status that restricts it from being produced in-house (e.g., "Blocked" or "Inactive").
  
  
  Capacity Constraints: There may be capacity constraints in the production resources that prevent the material from being produced.
  
  
  Solutions:
  
  
  Check Material Master: Go to the material master (transaction code MM03) and verify the production type settings. Ensure that the material is marked for in-house production.
  
  
  Review Routing: Check if a valid routing exists for the material (transaction code CA03). If not, create or assign a routing that defines the production process.
  
  
  Verify BOM: Ensure that a valid BOM exists for the material (transaction code CS03). If it is missing, create a BOM that lists all the components required for production.
  
  
  Plant Configuration: Review the plant settings to ensure that in-house production is allowed for the material. This can be checked in the configuration settings.
  
  
  Check Material Status: Verify the material status in the material master. If it is blocked or inactive, change it to an active status.
  
  
  Capacity Planning: Review the capacity planning for the production resources. If there are constraints, consider adjusting the production schedule or resources.
