• What is the cause and solution for SAP error message K6655 - Caution: Formulas disable the functions (revaluation etc.) ?

  The SAP error message K6655, which states "Caution: Formulas disable the functions (revaluation etc.)," typically occurs in the context of SAP Controlling (CO) when working with cost center accounting or internal orders. This message indicates that there are formulas in the cost planning or cost allocation that are preventing certain functions, such as revaluation or actualization, from being executed properly.
  Cause:
  
  Formulas in Planning: The presence of formulas in the planning layout can restrict the execution of certain functions. For example, if you have defined a formula for calculating costs, it may not allow for standard revaluation processes to occur.

  Data Integrity Issues: If the formulas lead to inconsistencies or errors in the data, it can trigger this warning.
  
  Solution:
  
  Review Formulas: Check the formulas used in your planning layouts. Ensure that they are necessary and correctly defined. If possible, simplify or remove formulas that are not essential.
  Adjust Planning Layout: If the formulas are causing issues, consider adjusting the planning layout to use standard cost elements or methods that do not interfere with revaluation functions.
  Test Changes: After making adjustments, test the planning process to ensure that the error does not reoccur and that the functions you need (like revaluation) can be executed successfully.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines on using formulas in planning and their impact on functions.
  Seek Expert Help: If the issue persists, consider consulting with an SAP expert or your internal SAP support team for further analysis and resolution.
