HI,

You can use refresh, clear stements to clear the selectio-screen values.

e.g. if s_matnr is the selection variable, you can clear the values using refresh s_matnr[], clear s_matnr. In the same way you can clear the parameters using clear key word. (clear p_test).

Hi,

Use AT SELECTION-SCREEN OUTPUT event to clear the select-options field values.

Hi Gary,

Put an Authorisation code in the Initailization Event. It will resolve your problem.If you want to refresh or change the value in the selection criteria then what you need to do is just enter the value in the event " AT SELECTION SCREEN OUTPUT".

You can follow the below steps:

1. Use function module DYNP_VALUES_READ to read the current values of the fields on the screen.

2. Then change the values after your check and...

3. Use function moudule DYNP_VALUES_UPDATE to update the changed field values on the screen.

I used these to update the current screen values. Let me know if you need more details.

Thx,

Raj.

DYNP_VALUES_READ Read the values from a dynpro. This function can be used to read the values from a report's selection screen too

DYNP_VALUES_UPDATE Similar to DYNP_VALUES_READ, this function will allow the updating of fields on a dynpro. Very useful when you want to change a field based on the value entered for another field.

*********

The following code shows the syntax of the FM 'DYNP_VALUES_UPDATE'.

*Internal table to store dy dynpro fields and values

DATA: dynpfields LIKE dynpread OCCURS 5 WITH HEADER LINE.

DATA: l_stepl LIKE sy-stepl.

REFRESH dynpfields.

CLEAR dynpfields.

dynpfields-fieldname = 'SCREENFIELD1-COL1'. "Screen field name

dynpfields-fieldvalue = 10. "New value

dynpfields-stepl = l_stepl. "Step loop for table controls

APPEND dynpfields.

CALL FUNCTION 'DYNP_VALUES_UPDATE'

EXPORTING

dyname = 'SAPLBDT_GMGR' "Program name

dynumb = '0270' "Screen number

TABLES

dynpfields = dynpfields

EXCEPTIONS

OTHERS = 0.

Hi Gary,

You can put the authority check in at selection-scree event and before that event put an intialization event also.

FORM authority_check.

Checking Whether the User has authorization for the Plant.

AUTHORITY-CHECK OBJECT 'ZMMD_PROD' ID 'WERKS' FIELD pa_werks.

IF sy-subrc <> 0.

NO AUTHORIZATION FOR PLANT.

MESSAGE e167

ENDIF.
