[#1]

I have a table containing a date field but not all rows in the database have a date since some rows represent children to a previous row and in the application they inherit the date from the parent row by default.

In order for this to work in QlikView I would like to replace any null in the date field with the date from the previous row with an existing date (since that row will always be the parent)

Example of the table:

ActivityID	ActivityChild	Date
4613	-	2013-09-23
4614	-	2013-09-27
4615	4614	-
4619	4614	-
4620	4614	-
4621	4614	-
4616	4614	-
4617	4614/4616	-
4618	4614/4616	-
4622	-	2013-11-23
4623	4622	-
4628	4622	-
4624	4622	-
4625	4622	-

How I want the data to look:

ActivityID	ActivityChild	Date
4613	-	2013-09-23
4614	-	2013-09-27
4615	4614	2013-09-27
4619	4614	2013-09-27
4620	4614	2013-09-27
4621	4614	2013-09-27
4616	4614	2013-09-27
4617	4614/4616	2013-09-27
4618	4614/4616	2013-09-27
4622	-	2013-11-23
4623	4622	2013-11-23
4628	4622	2013-11-23
4624	4622	2013-11-23
4625	4622	2013-11-23

How can I do this? Any help would be appreciated!

You can use the peek function to populate the fields. See an example here: http://community.qlik.com/blogs/qlikviewdesignblog/2013/02/05/populating-a-sparsely-populated-field

Thanks alot. I got stuck on trying to use Previous instead of Peek which was why I couldn't get it to work. Now it's perfect!
