  The SAP error message GB520, which states "Field length (&) is less than (&)," typically occurs when there is a mismatch between the expected length of a field and the actual length defined in the data structure or configuration. This error is often encountered in the context of data entry, data import, or during the execution of certain transactions where field lengths are critical.
  Cause:
  
  Field Length Mismatch: The error arises when the length of the data being processed exceeds the defined length of the field in the database or data structure.
