ROLLBACKSXE()
RollbackSxe()Discards a numbering reservation in the legacy flow.
Overview
Training describes discarding the number reserved by the last GetSxeNum. This does not roll back a SQL transaction, delete a saved document or establish equivalence with RollbackSX8 by name alone. Reservation ownership determines who confirms or discards. The TOTVS article shows MATA410 may manage its own numbering; extra numbering calls and C5_NUM in the automatic array must then be removed. The block is not executed without a caller-owned reservation. (Sources: refs. 1–2.)
Syntax
RollbackSxe()Return value
Unspecified in the selected reference; not used as Boolean.
