i ant to change the way i write it but i have error how can i solve it?

Regards

CALL METHOD leaf_ref->find_leaf    "working o.k. 
       EXPORTING
         node_tab = node_tab
        RECEIVING
          leaf_tab = leaf_tab.

have Error :

leaf_tab = leaf_ref->find_leaf( node_tab ) .

You can only omit the parameter name if the method only has a

non-optional parameter or an optional IMPORTING parameter that is

identified by "PREFERRED PARAMETER". by "PREFERRED PARAMETER".

well you once again need thet "call method" thingie.

best way not to stumble into such things is to use the pattern-button in SE80.

select pattern for ABAP-OO and hit ENTER. Rest should be self explaining.

Hi Cosmo Kramer,

Why do you want to go for the second way...

The Best way while working with patterns is the best way to get rid of those errors... The functionality is

for both the ways.. in that case i agree with you...

So why dont you go with the first way... and use PATTERN option in the editor...

And Use the PATTERN if you are using the global classes..

Go with the second method if you are defining local classes..

Hope this would help you.

Good luck
