• What is the cause and solution for SAP error message W0020 - Only one table can be maintained for every key figure category ?

  SAP Error Message:
  
  W0020 - Only one table can be maintained for every key figure category
  
  Cause:
  This warning message occurs in SAP when you try to assign more than one table to the same key figure category in the configuration of key figures (often in controlling or profitability analysis). The system expects that for each key figure category, only one table can be maintained to avoid ambiguity or conflicts in data assignment.
  In other words, the key figure category is designed to link to a single table, and if multiple tables are assigned, the system raises this warning to prevent inconsistent or incorrect data processing.
  
  Where it typically occurs:
  
  In CO-PA (Profitability Analysis) customizing, when defining key figure categories and their assignment to database tables.
  During configuration of key figures in Controlling or Profit Center Accounting.
  When maintaining table assignments in transaction codes like KE4I, KE4T, or related customizing transactions.
  
  
  Solution:
  
  Check the configuration for the key figure category in question.
  Ensure that only one table is assigned to each key figure category.
  If multiple tables are assigned, decide which table is the correct one for the key figure category and remove the others.
  Save the configuration after correcting the assignment.
  
  
  Steps to resolve:
  
  Go to the customizing transaction where key figure categories and tables are maintained (e.g., SPRO ? Controlling ? Profitability Analysis ? Master Data ? Key Figures).
  Identify the key figure category causing the warning.
  Review the tables assigned to this key figure category.
  Remove any additional tables so that only one table remains assigned.
  Save and test the configuration.
  
  
  Additional Information:
  
  This is a warning message (W0020), so it may not stop the process but indicates a configuration issue that should be corrected.
  Maintaining only one table per key figure category ensures data consistency and correct reporting.
  If you need to report on multiple tables, consider defining separate key figure categories for each table.
  Refer to SAP documentation or OSS notes related to CO-PA key figure configuration for more detailed guidance.
