• What is the cause and solution for SAP error message WS391 - Valuation data could not be blocked for all materials ?

  SAP Error Message:
  
  WS391 - Valuation data could not be blocked for all materials
  
  Cause:
  This error typically occurs during a mass valuation or material blocking process when the system attempts to block valuation data for multiple materials but fails for one or more materials. The failure can be due to:
  
  The valuation data for some materials is already blocked or locked by another user/process.
  Inconsistent or missing valuation data for certain materials.
  Authorization issues preventing the blocking of valuation data.
  The materials might be in a status or condition that does not allow blocking (e.g., materials are in use in a process that prevents blocking).
  Technical issues such as database locks or update failures.
  
  
  Explanation:
  In SAP, valuation data blocking is used to prevent changes to the valuation of materials during critical processes like inventory closing or period-end closing. When the system cannot block valuation data for all selected materials, it raises WS391 to indicate partial failure.
  
  Solution:
  
  
  Check Lock Entries:
  
  Use transaction SM12 to check if there are any locks on the valuation data of the materials.
  If locks exist, determine if they can be released safely.
  
  
  
  Verify Material Valuation Data:
  
  Check if valuation data exists for all materials in the relevant valuation areas and valuation types.
  Use transaction MM03 to review material valuation views.
  Ensure that the materials are not flagged for deletion or have inconsistent data.
  
  
  
  Authorization Check:
  
  Confirm that the user performing the blocking has the necessary authorizations (e.g., authorization object M_MATE_WRK for material master changes).
  
  
  
  Review Process Status:
  
  Ensure that no other process (e.g., inventory count, goods movement) is currently using or locking the materials.
  Wait for any batch jobs or background processes to complete.
  
  
  
  Retry the Blocking:
  
  After resolving locks or data issues, retry the blocking process.
  Use transaction MMBE or relevant valuation blocking transactions (e.g., MR21, MR22, or custom programs) depending on your process.
  
  
  
  Check for OSS Notes:
  
  Search SAP Support Portal for OSS Notes related to WS391 for your SAP version.
  Sometimes, SAP provides patches or corrections for known issues.
  
  
  
  
  Related Information:
  
  
  Transaction Codes:
  
  SM12 – Display and delete lock entries.
  MM03 – Display material master.
  MR21 – Price change for material.
  MR22 – Change material valuation data.
  Custom or specific transactions used in your organization for valuation blocking.
  
  
  
  SAP Modules Involved:
  
  MM (Materials Management)
  FI (Financial Accounting) – for valuation and inventory accounting
  CO (Controlling) – for product costing and valuation
  
  
  
  Typical Scenario:
  
  During period-end closing, companies block valuation data to prevent changes.
  If the system cannot block all materials, it raises WS391 to alert the user.
  
  
  
  
  Summary:
  WS391 indicates that the system could not block valuation data for all materials, usually due to locks, missing data, or authorization issues. To resolve, check and clear locks, verify material valuation data, ensure proper authorizations, and retry the blocking process.
