  • What is the cause and solution for SAP error message GT324 - DDL lock set by tp (D0GEN) ?
    The SAP error message GT324, which indicates a "DDL lock set by tp (D0GEN)," typically occurs during database operations when a Data Definition Language (DDL) statement is trying to access a database object that is currently locked by another process.
