How to make a fld mandatory in module pool program?

Question

I need help on following 2 things
I have module pool program created, in that many screen subscreens created.
1.I want to make a field mandatory
second one  is, I have a general tab and  data tab.
General tab screen - 2101
Data tab = 2102
In general tab, I have edited the values (change mode), when change the values and try to save it,
It is holding old value.but If i exucute the transaction once again, it is showing the changed value(new value)
For ex: there is a date field  value is 03/08/2009
If I change this to 03/09/2009 and press on Save button from the standard menu, still it is showing the  value 03/08/2009. but I execute this transaction once again it is showing the value as 03/09/2009
I will be thankful if someone helps me here

Hi Chitra,
Go to the properties of the filed select program tab and say input required.
then you will get the problem solved.
For second one actually its saving but not displaying the saved value at the same time ,
for this you write the select statement after saving , so that once save is execute m, select statement also will execute  and it will display the newly saved value.
so after saving imdeatly u write the select statement.
like case sy-ucomm.
when 'SAVE'.
insert ztable.
select filed from z table.
endcase.
let me know if ur problem solved.
