at selection-screen on p_field.

if p_field > 0.

clear p_field.

endif.

Hi

Once you execute the report the selection screen is displayed

You can clear the SELECT-OPTIONS and PARAMETERS values in the INITIALIZATION event

write CLEAR < field> in the initialization event and see.

Hi,

try this..

CLEAR ( <parameter> ).

This function clears the contents of the parameter – that is, it initializes the given field or fields. <parameter> can be a:

Simple parameter

Field of a structured parameter

CLEAR ( <structure>-<field1> ).

Complete structure

CLEAR ( <structure> ).

Complete table row

CLEAR ( <table>[<index>] ).

Complete table

CLEAR ( <table> ).

Hi,

CHeck is there any SET/GET paramters that are used in AT SELECTION-SCREEN PUTPUT Event block of the report.

Otherwsie if you just clear your paramters it should clear he values, I think they are getting the values from some global memory like SAP Memory. If yo uclear the values at the event block AT SELECTIOn-SCREEN you should not get any values back.

Check the code in event blocks AT SELECTIOn-SCREEN OUTPUT

and AT SELECTION-SCREEN.

Hi,

its not a selection screen ,

just parameters: field.

after program is over, i should clear that parameter field. what i mean is once saved ,the parameter field should be blank.

Hi,

Can you show us your code, it would be easyto findthe problem then.

If yours is a simple report program with PARAMTERS, this will internally create a SELECTIOn-SCREEN.

Any way just put your clear statement after the SAVE functionality.

Hi,

Run in DEBUG mode and find out weather clear is getting executed or not.

ALso check when is getting value again.

Put your clear statements outside the IF ENDIF.

Are you sure your are entring these IF's.
