Hi,

I have date field in form.
I want previous date before changing,is there any built in to trap the previous date just before changing the date.

Ex:In my purchase date field i have:

02-jan-2007

I change it to 04- mar-2007

So i should have a built in to trap before date i.e,
02-jan-2007.

Same way i go on changing the date,but i want to keep track of just before old date even after changing.

again i change the date 04- mar-2007 to 05-jun-2009

So i should have track of 04- mar-2007 .

Please let me know do we have any built to track exact previous value/date.

Please let know other than global parameters or record groups.

Thanks,
Srinivas

You might create a database trigger which would take notes of values' changes on this table.

Have you solved your problem?

You could create a non-database item on the record (eg original_date) and populate it in the Post-Query trigger. Then each time you change the database value you can perform some logic and then in the Post-Commit trigger assign the new value to the 'original_date' value so that it conforms to the value stored in the database.

In the database an update trigger will have the ':new.purchase_date' and ':old.purchase_date' values available to it.
