• What is the cause and solution for SAP error message W_CB170 - Field list number must not be entered ?

  Certainly! Here's a detailed explanation for the SAP error message W_CB170: "Field list number must not be entered":
  
  SAP Error Message: W_CB170
  Text: Field list number must not be entered
  
  Cause
  This warning message typically occurs in the context of SAP Controlling (CO), especially when dealing with cost center reports, planning, or data entry screens where a "field list number" is involved.
  
  The message indicates that the user has entered a field list number in a place where it is not allowed or expected.
  In many SAP CO transactions or reports, the system expects either a field list name or no entry at all, but not a numeric field list number.
  This can happen if the user mistakenly inputs a numeric value (field list number) instead of selecting or leaving the field blank.
  It may also occur if the configuration or selection screen is designed to accept only certain types of input, and the user input violates this.
  
  
  When does it occur?
  
  During cost center planning or reporting when selecting or entering field lists.
  When using certain standard reports or custom reports that have parameters for field lists.
  When the user tries to enter a field list number in a parameter that expects a field list name or no entry.
  
  
  Solution
  
  
  Check the input field:
  
  Ensure that you are not entering a numeric field list number where the system expects a field list name or no entry.
  If the field is optional, try leaving it blank.
  
  
  
  Use the correct field list:
  
  If you need to specify a field list, use the field list name (usually alphanumeric) rather than a number.
  You can find valid field list names in the system documentation or by using the search help (F4) on the input field.
  
  
  
  Review the selection screen or report parameters:
  
  Verify the documentation or help for the transaction/report to understand what input is expected.
  If this is a custom report, check with the developer or functional consultant to clarify the expected input.
  
  
  
  Check configuration:
  
  If you are an administrator or consultant, verify the configuration of field lists in the controlling area.
  Make sure that the field lists are properly defined and that the selection screens are correctly set up.
  
  
  
  
  Additional Information
  
  Field lists in SAP CO are used to define sets of fields for reporting or planning.
  The system distinguishes between field list names (identifiers) and field list numbers (internal IDs).
  The error message is a warning (W_), so it may not stop processing but indicates incorrect input.
  If you repeatedly encounter this message, consider reviewing user training or documentation to clarify correct input procedures.
