This is all about the runtime error :-

Incorrect parameter with CALL FUNCTION

Error analysis :-

An exception occurred that is explained in detail below.

The exception, which is assigned to class 'CX_SY_DYN_CALL_PARAM_MISSING', was

not caught in

procedure "HIDE_FIELDS" "(FORM)", nor was it propagated by a RAISING clause.

Since the caller of the procedure could not have anticipated that the

exception would occur, the current program is terminated.

The reason for the exception is:

When calling the function module "ZCFM_HIDE_INITIALFIELD_ALV", one of the

parameters

needed according to the interface description was not specified.

This parameter was "IT_TAB1".

I am not changing the function module, my couligue has change this he leave it & he doesn't tel to me. So pls. give some sol. to me.

Thanks,

Sumit.

Hi,

Through out the code I could see that internal table IT_ITAB1 is not used anywhere in the program. I feel instead of removing internal table IT_ITAB1 from declaration, open function module ZCFM_HIDE_INITIALFIELD_ALV in SE37 -> go to Tables tab and select optional check box against internal table IT_ITAB1 and activate it.

Reply back if it doesn't work.

Also, for your future reference, use transaction ST22 where you can understand the reason of why run time error occured.

You can yourself zero it down.
