Parameter Validation

Former Member — Tue, 10 Oct 2006 05:38:28 GMT

Hi,

I would like to validate two parameters in the selection screen at the same time. How can I perform it? I will explain in detail. There are two parameters: lvstartdt and lvenddate. I need to check a record (before going for further processing) in the table PA2001 for the dates given in lvstartdt and lvenddate. If there is no such record, I need to give an error message without exiting from the selection screen. Please help me..

Good solutions will be rewarded...

Best Regards

Renjan

you can do this at selection screen output

at selection-screen output

if not lv_startdt is initial.

*Do your validation here

if sy-subrc ne 0.

set cursor field 'LV_STARTDT'.

*error message

endif.

if not lv_enddt is initial.

*Do your validation here

if sy-subrc ne 0.

set cursor field 'LV_ENDDT'.

*error message

endif.

Hi,

Use the "At selction screen" event.

eg.

At selection-screen.

select single *

from table

where date1 EQ lvstartdt

and date2 EQ lvenddate.

if sy-subrc NE 0.

message e001(msg_class).

enndif.

This should solve ur problem.

Hi,

At selection-screen output.

if not ( lvstartdt is initial and lvenddate is initial ).

select * from pa2001 into table t_pa2001 up to 1 rows

where condition.

else.

message e000 with 'Enter valid date'.

leave list-processing.

endif.
