Internal System Fields
Internal system fields are intended solely for internal use within the ABAP runtime environment and in the kernel. They must never be overwritten from within an ABAP program and they cannot even be accessed in read-only mode.

sy-oncom |
c |
1 | "On Commit" flag. This system field is set to different values depending on the call status of theABAP program. Among these, only the meaning of the value 'P' is guaranteed . If queried at all, sy-oncom can only be queried for 'P'. The value 'P' means that the program is already executinga subroutine registered using PERFORM ... ON COMMIT and a further subroutine call using PERFORM ... ON COMMIT produces a runtime error. |
