Problem in Refresh ALV Tree...

[keyur_pawar]

Hello Friends,

Right now i'm dealing with ALV Tree.

My Problem is,

When I Execute my program first time It run properlly,

but when I execute it next time with differnt set of INPUT,

It throws an DUMP i.e. "Field symbol has not yet been assigned."

Here is the reason:

     "IS_OUTTAB_LINE" this structure always contains data of previous set of INPUT (not current).

& I can not manually clear this sructure coz it is inside the built in method "set_hierarchy_data".

(It means this structure didn't capture Current ITAB's Line type)

So, what should I do to make refresh or Clear this structure.

Thanks in Advance.....

Regards,

KEYUR PAWAR.

You might be creating the class object somewhere in your statement

You have to close that object.

Since you are rerunning with diferent values, since the old object exist... during catalog cretion it will throw error.

Give me the code, i shall point out where to write this clear object satement
