Re: How to declare null values in abap reports

Hello,

The correct code can be either of the following:

1.  ( i_taxnum IS INITIAL ) AND ( i_taxtype NE space ).

2.  ( i_taxnum IS INITIAL ) AND ( i_taxtype IS NOT INITIAL).

'IS' Comes with Keywords 'INITIAL' and 'NOT INITIAL' but IS can not be used when you are comparing two variable using an operator (i_taxtype IS NE space).

Mind you SPACE is not a keyword in ABAP it is a variable with type CHAR1 and value = BLANK and NE is an operator.

Hope it helps.
