  The SAP error message FINS_FI_CLS026 indicates that a customer-defined grouping rule is not valid because it starts with a number. In SAP, certain naming conventions must be followed, and one of those conventions is that identifiers (like grouping rules) cannot begin with a numeric character.

  Identify the Grouping Rule: Determine which grouping rule is causing the error. The error message will typically include the name of the grouping rule (represented by &1).
  
  
  Rename the Grouping Rule:
  
  Go to the transaction or area in SAP where you can manage grouping rules (this could be in the configuration settings for financials).
  Locate the grouping rule that is causing the issue.
  Edit the name of the grouping rule to ensure it starts with a letter (A-Z, a-z) instead of a number.
  
  
  
  Save Changes: After renaming the grouping rule, save your changes.
  
  
  Test: Try to execute the action that previously caused the error to ensure that the issue has been resolved.
