• What is the cause and solution for SAP error message VMP_MSG299 - You are not authorized to change Bill of Material information ?

  SAP Error Message:
  
  VMP_MSG299 – "You are not authorized to change Bill of Material information"
  
  Cause:
  This error occurs because the user attempting to change the Bill of Material (BOM) does not have the necessary authorization. In SAP, BOM changes are protected by specific authorization objects to ensure that only users with the correct permissions can modify BOM data.
  
  Explanation:
  
  The user lacks the required authorization to perform change operations on BOMs.
  Authorization checks are performed against authorization objects related to BOM maintenance.
  Common authorization objects involved include:
  
  CS_A_BOM (Authorization for BOM)
  CS_A_OBJ (Authorization for BOM objects)
  CS_A_MAT (Authorization for material master data related to BOM)
  
  
  The user might have display authorization but not change authorization.
  
  
  Solution:
  
  
  Check User Authorizations:
  
  Use transaction SU53 immediately after the error occurs to display the last failed authorization check.
  Identify which authorization object and field values are missing.
  
  
  
  Grant Required Authorizations:
  
  The user needs authorization for the relevant authorization objects, typically:
  
  CS_A_BOM with activity '02' (Change)
  CS_A_OBJ with appropriate object type and activity
  CS_A_MAT if material master data is involved
  
  
  The authorization profile should include the correct plant, BOM usage, and material number ranges as applicable.
  
  
  
  Coordinate with Security Team:
  
  Request the SAP security or BASIS team to update the user’s roles/profiles to include the necessary authorizations.
  Ensure that the roles assigned to the user include the ability to change BOMs.
  
  
  
  Verify After Authorization Update:
  
  After the authorization is granted, retry the BOM change transaction to confirm the issue is resolved.
  
  
  
  
  Related Information:
  
  
  Transactions for BOM Maintenance:  
  
  CS01 (Create BOM)  
  CS02 (Change BOM)  
  CS03 (Display BOM)
  
  
  
  Authorization Objects:
  
  CS_A_BOM – BOM authorization (activities like display, change, create)
  CS_A_OBJ – BOM object authorization
  CS_A_MAT – Material master authorization related to BOM
  
  
  
  Useful Transactions:
  
  SU53 – Display last authorization check failure
  PFCG – Role maintenance (for security admins)
  SE16N – To view authorization objects and user assignments
  
  
  
  SAP Notes and Documentation:
  
  Check SAP OSS notes related to VMP_MSG299 for any system-specific issues.
  SAP Help Portal documentation on BOM authorization.
  
  
  
  
  Summary:
  The error VMP_MSG299 is an authorization issue preventing the user from changing BOM data. The solution is to identify the missing authorizations using SU53 and then assign the appropriate roles/authorizations that allow BOM changes. Coordination with the SAP security team is usually required to resolve this.
