GP155 - Details

• The SAP error message GP155 "No free numbers available in the number interval" typically occurs in the context of number ranges in SAP, particularly when dealing with document numbers, transaction numbers, or other identifiers that require unique numbering. This error indicates that the system has exhausted the available numbers in the defined number range interval.
