• What is the cause and solution for SAP error message BOM101 - Sales order requires BOM category "K" ("order BOM") ?

  The SAP error message BOM101 indicates that a sales order requires a Bill of Materials (BOM) of category "K," which stands for "order BOM." This error typically arises when you are trying to create or process a sales order that requires a specific type of BOM that is not available or not correctly configured in the system.
  Cause:
  
  Missing Order BOM: The sales order item you are trying to process requires an order BOM, but one has not been created or is not available for the specified material.
  Incorrect BOM Category: The BOM that exists for the material may not be of the correct category (i.e., it may be a standard BOM instead of an order BOM).
  Configuration Issues: There may be configuration issues in the material master or BOM settings that prevent the system from recognizing the appropriate BOM.
  
  Solution:
  
  
  Create an Order BOM:
  
  Go to the BOM creation transaction (e.g., CS01) and create a new BOM for the material with the category "K" (order BOM).
  Ensure that the BOM is correctly assigned to the relevant sales order item.
  
  
  
  Check Existing BOMs:
  
  Use transaction CS03 to display existing BOMs for the material and verify if an order BOM exists.
  If an order BOM exists but is not being recognized, check the validity dates and the status of the BOM.
  
  
  
  Review Material Master Settings:
  
  Check the material master record (transaction MM03) to ensure that the material is set up correctly for BOM usage.
  Ensure that the relevant views (e.g., MRP, Sales) are properly maintained.
  
  
  
  Consult with Configuration Team:
  
  If you are unsure about the configuration settings, consult with your SAP configuration team to ensure that the system is set up to handle order BOMs correctly.
  
  
  
  Check Sales Order Configuration:
  
  Ensure that the sales order type and item category are configured to allow for the use of order BOMs.
