Thanks for reading my post. I am a new Mbr to the Forum.
I have been given a tricky assignment and thought I'd ask the group to see if anyone has done this themselves or anything similar to it. It involves transforming Eligibility Coverage Periods, and there are some complex rules around what is being pulled from the Source ODS Tables. What I need to do is probably best explained with an example. There is a Memberid, Groups, Startdates and Termdates.

A Mbr belongs to Group abc with one Coverage Period.

mbrid: 123
group: abc
Startdate: 1/1/2000
Enddate: 12/31/2005

and this member also belongs to Group xyz with several periods.

mbrid: 123
group: xyz
Startdate: 1/1/2001
Enddate: 12/31/2001

mbrid: 123
group: xyz
Startdate: 1/1/2003
Enddate: 12/31/2003

mbrid: 123
group: xyz
Startdate: 1/1/2005
Enddate: 12/31/2005

In this example Group xyz's coverage periods takes priority so I need to pull those periods first

123, xyz, 1/1/2001, 12/31/2001
123, xyz, 1/1/2003, 12/31/2003
123, xyz, 1/1/2005, 12/31/2005

Now I need to recognize that group abc has one large period which overlaps the ones I just imported and so I need to make smaller spans for years 2000, 2002, and 2004.

Final Results should look like this

123, abc, 1/1/2000, 12/31/2000
123, xyz, 1/1/2001, 12/31/2001
123, abc, 1/1/2002, 12/31/2002
123, xyz, 1/1/2003, 12/31/2003
123, abc, 1/1/2004, 12/31/2004
123, xyz, 1/1/2005, 12/31/2005

Any advice, code, thoughts, etc. is greatly appreciated
