This poster usually includes a desperate plea for help in the title but then no information whatsoever in the body of the post.  We can tell you need help, but with what? Help us help you!

Well, that wasn't very helpful. Why not point out something like this instead: QlikCommunity Tip: How to get answers to your post?

Re: SCD Logic??

Raju,

If you understand the logic of SCDs then you can easily implement SCDs in QV on your own...

In general the requirement would be more of implementing Type 2 SCDs... ie preserving history...

So.. How to preserve the history... as per Kimbal's DW Model there are essentially three types..

1) Versioning

2) Timestamp

3) Flags

Its your choice, how you would like to implement these options in QV...

HTH
