  The SAP error message /PLMI/PPE_BO011 indicates that there is an attempt to create an assembly relationship between a component item and a header item that already exists in the system. This typically occurs in the context of Product Lifecycle Management (PLM) or Production Planning (PP) when trying to define or modify the relationship between a bill of materials (BOM) or assembly structure.
  Cause:
  The error is triggered when:
  
  You are trying to create a new assembly relationship (e.g., adding a component to a BOM) that already exists.
  There may be a duplicate entry in the database for the same component and header combination.
  The system is enforcing data integrity rules to prevent duplicate relationships.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Existing Relationships:
  
  Use transaction codes like CS03 (Display BOM) or CS02 (Change BOM) to check if the assembly relationship already exists between the specified item and header.
  Look for the specific component and header combination mentioned in the error message.
  
  
  
  Modify or Delete Existing Relationships:
  
  If the relationship already exists and you need to make changes, consider modifying the existing relationship instead of creating a new one.
  If the existing relationship is incorrect or no longer needed, you can delete it using CS02.
  
  
  
  Review Input Data:
  
  Ensure that the data you are trying to input is correct and does not inadvertently create a duplicate relationship.
  Double-check the item numbers and header numbers for any typos or discrepancies.
