Checking Numeric Variable

If the field/variable is of type <b>CURR</b>, system will do a automatic check.

If you want to have your own check you could try the following (taken from ABAP key word documentation).

DATA I TYPE I. 
*** CONVERSION_ERRORS contains CONVT_NO_NUMBER *** 
CATCH SYSTEM-EXCEPTIONS CONVERSION_ERRORS = 1. 
  MOVE 'abc' TO I.          " <- Error: CONVT_NO_NUMBER 
ENDCATCH. 
IF SY-SUBRC = 1. 
  ... 
ENDIF. 

Hope this helps.
