• What is the cause and solution for SAP error message VMP_MSG377 - Routing profile allows only one MBOM assignment ?

  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  VMP_MSG377: Routing profile allows only one MBOM assignment
  
  Cause:
  This error occurs when you try to assign more than one Manufacturing Bill of Materials (MBOM) to a routing profile that is configured to allow only a single MBOM assignment.
  
  Routing Profile in SAP controls how routings and MBOMs are linked.
  Some routing profiles are set up to allow only one MBOM assignment per routing.
  If you attempt to assign multiple MBOMs to such a routing profile, the system throws this error.
  
  
  Explanation:
  
  The routing profile defines the rules for MBOM assignment.
  If the profile is set to single MBOM assignment, it means each routing can be linked to only one MBOM.
  Trying to assign a second MBOM to the same routing with this profile violates the rule.
  
  
  Solution:
  
  
  Check the routing profile settings:
  
  Go to transaction SPRO ? Logistics Execution ? Production ? Master Data ? Routing ? Define Routing Profiles.
  Find the routing profile used in your routing.
  Check the setting related to MBOM assignment (usually a checkbox or indicator for "Allow multiple MBOM assignments").
  
  
  
  Adjust the routing profile if multiple MBOMs are needed:
  
  If your business process requires multiple MBOMs per routing, change the routing profile to allow multiple MBOM assignments.
  Be cautious: changing this setting can have broader impacts on production and planning processes.
  
  
  
  Alternatively, assign only one MBOM per routing:
  
  If the routing profile must remain as is, ensure that only one MBOM is assigned to each routing.
  Review your MBOM assignments and remove any duplicates or extra assignments.
  
  
  
  Check MBOM assignment transactions:
  
  When creating or changing MBOMs, ensure you are not assigning multiple MBOMs to the same routing profile that restricts to one.

  Summary:
  
  Error: You assigned multiple MBOMs to a routing profile that allows only one.
  Fix: Either change the routing profile to allow multiple MBOMs or assign only one MBOM per routing.
  Check: Routing profile settings in SPRO and MBOM assignments.
