  The SAP error message GC829 indicates that a document contains too many detail lines, exceeding the maximum limit of 999 lines. This error typically occurs in financial documents, such as invoices or journal entries, where the number of line items exceeds the system's predefined limit.

However, this should be approached with caution, as it may involve significant changes to the system and could have implications for performance and maintainability.
