CHECK evaluates the subsequent logical expression. If it is true, the processing continues with the next statement.

CHECK with a negative outcome terminates the current loop pass and goes back to the beginning of the loop to start the next pass, if there is one.

Outside loops, a CHECK with a negative outcome will cause you to exit the current processing block (event block, dialog module, procedure). During the reporting event GET, the system terminates the processing of the current entry, read by the logical database, and processes the next entry in the current node of the logical database. Nodes that are subordinate in the hierarchical structure of the logical database are not processed.

SAP recommends that you only use CHECK within loops. Use the RETURN statement to exit processing blocks.

You can use the REJECT statement to exit the reporting event GET conditionally.

Reward points if it helps

Hi Srisaihari,

CHECK statement just evalutes logical expression and if it is true it will execute all statements under CHECK.If it is false then it just ignores the statements under it.

For simple understand CHECK is very similar to IF...ENDIF.

But it plays very significant role with LOGICAL DATABASES with SELECT-OPTIONS.

To know more about this, use the folloing link.
