Smart SAP Assistant

• What is the cause and solution for SAP error message RTGP_APP001 - Root BOM required when creating routing component assignments ?

  The SAP error message RTGP_APP001, which states "Root BOM required when creating routing component assignments," typically occurs when you are trying to create or assign components in a routing without having a valid Bill of Materials (BOM) defined for the material in question. This error indicates that the system requires a root BOM to be in place before you can proceed with the routing component assignments.
  Cause:
  
  Missing Root BOM: The primary cause of this error is that there is no root BOM defined for the material you are working with. A root BOM is essential as it serves as the foundational structure for the components that will be used in the routing.
  Incorrect Material Master Data: The material master data may not be correctly set up to reference the appropriate BOM.
  BOM Status: The BOM might be inactive or not released, which prevents it from being used in routing assignments.
  
  Solution:
  To resolve the RTGP_APP001 error, you can follow these steps:
  
  
  Check BOM Existence:
  
  Go to the BOM transaction (CS03) and check if a BOM exists for the material you are trying to assign components to.
  Ensure that the BOM is for the correct plant and is marked as active.
  
  
  
  Create or Update BOM:
  
  If no BOM exists, create a new BOM using transaction CS01.
  If a BOM exists but is inactive, you may need to activate or release it using transaction CS02.
  
  
  
  Verify Material Master Data:
  
  Check the material master data (transaction MM03) to ensure that the BOM is correctly assigned to the material.
  Ensure that the material type and other relevant settings are appropriate for BOM usage.
  
  
  
  Check BOM Status:
  
  Ensure that the BOM is in a status that allows it to be used in routing. It should be released and not in a draft or inactive state.
  
  
  
  Routing Assignment:
  
  Once the BOM is confirmed to be in place and active, you can proceed with creating or modifying the routing component assignments.
  
  
  
  Related Information:
  
  BOM and Routing Relationship: In SAP, a BOM defines the components required to produce a product, while routing defines the operations and sequence of processes needed to manufacture that product. Both are essential for production planning and execution.
  Transaction Codes:
  
  CS01: Create BOM
  CS02: Change BOM
  CS03: Display BOM
  CA01: Create Routing
  CA02: Change Routing
  CA03: Display Routing
  
  
  SAP Documentation: Refer to SAP Help documentation for detailed information on BOM and routing management.
  
  By ensuring that a valid root BOM is in place and correctly linked to the material, you should be able to resolve the RTGP_APP001 error and proceed with your routing component assignments.
