• What is the cause and solution for SAP error message CK391 - Only the tax prices can be updated ?

  The SAP error message CK391 ("Only the tax prices can be updated") typically occurs in the context of material valuation and pricing in SAP, particularly when dealing with the Material Ledger or when trying to update prices in the system. This error indicates that the system is preventing updates to certain price fields because they are not allowed to be changed under the current conditions.
  Cause:
  
  Price Control Settings: The material may be set to a specific price control (e.g., moving average price or standard price) that restricts updates to certain fields.
  Locked Fields: The fields you are trying to update may be locked due to the current status of the material or the document you are working with.
  Tax Price Update: The system is configured to allow only tax prices to be updated, which means that other price fields are not editable in the current context.
  Document Type Restrictions: Certain document types may have restrictions on what can be updated, especially in the context of financial postings.
  
  Solution:
  
  Check Material Master Settings: Review the material master data to ensure that the price control settings are appropriate for the updates you are trying to make. If the material is set to "Standard Price," you may need to adjust the price through a different transaction (e.g., CK40N for price changes).
  Review Document Status: Ensure that the document you are trying to update is not in a status that prevents changes. For example, if it is already posted, you may need to reverse or adjust the posting.
  Use Correct Transaction: Make sure you are using the correct transaction for the type of update you are trying to perform. For example, if you are trying to change the price of a material, use the appropriate transaction code (e.g., MR21 for changing the price of a material).
  Consult with SAP Basis or Functional Team: If you are unsure about the settings or restrictions, consult with your SAP Basis or functional team to understand the configuration and any potential limitations.
