ID CHECK • CHECK - processing block ABAP Statement
CHECK, processing_block Short Reference
ABAP_SYNTAX CHECK log_exp.
What does it do? If the statement CHECK is listed outside a loop and log_exp is false, it terminates the current processing block. Any logical expression can be specified for log_exp. After the processing block is exited, the runtime framework behaves in the same way as when the processing block is exited in the regular way BEGIN_SECTION VERSION 5 OUT , with the exception of the event block LOAD-OF-PROGRAM and the reporting event block GET END_SECTION VERSION 5 OUT . In particular, the output parameters of procedures are passed on to the bound actual parameters. BEGIN_SECTION VERSION 5 OUT
The event block LOAD-OF-PROGRAM cannot be exited using CHECK .
After the reporting event block GET is terminated using CHECK , any subordinate nodes in the hierarchy structure of the linked logical database are no longer processed. The logical database reads the next line of the current node or next higher node, if it has reached the end of the hierarchy level. END_SECTION VERSION 5 OUT
ABAP_PGL Only use RETURN to exit procedures ABAP_PGL_END
Latest notes:
In a procedure (a method, function module, or subroutine), CHECK log_exp works outside a loop in the same way as: IF NOT log_exp. RETURN. ENDIF. NON_V5_HINTS
A further variant of the statement CHECK for exiting processing blocks is CHECK SELECT-OPTIONS, which can only be used in GET event blocks for logical databases. ABAP_HINT_END
