  Check Account Configuration: Review the configuration of the account numbers and prefixes in your SAP system. Ensure that the prefix and the account number together do not exceed the 10-character limit.
  
  
  Modify Prefix or Account Number: If possible, consider changing the prefix to a shorter one or using a shorter account number that, when combined, does not exceed the 10-character limit.
