Gather and Report Data

Question

I have an input form that the user enters a date range, and the procedure calculates the cost of number of records found by cost per record. I already have a finished product, but I am being asked to make significant changes to the way the data is gathered. I was using the Next_Day function, which was working just fine, but I was told it wasn't foolproof enough sigh. I have the "spelled out" outline of what needs to be done, but I am having trouble knowing where to start. Here's an excerpt of what I need this part of the procedure to do:
For each Date from Start Date through End Date
If Monday
Gather and Display Week's Data
Week Begin Day = Date -7 ***Go get a week's worth of data, start Mon
Week End Day = Date -1 ***End on Sunday
For each Day from Week Begin Day through Week End Day
If Vendor Effective Date = Day
If Vendor not Obsolete
or Vendor Obsolete Date > Week End Day
then
Increment Weekly Count
Even if you can't provide me with actual code, I would like to know what you would recommend I should look at. Like, if you think such and such function or whatever would work well here, that would be a great help. Thanks!
Hmmm, my outline didn't space the way I wrote it. Sorry.

Hi,
Couple of things that would take a lot of time/effort in this scenario would be handling the master data issues(as there are bound to be master data synchronization issues) eg if product A1 and product A2 are indeed same but represented differently in two source systems - how to report them as if they are one and the same; and, exclusion of intra-business transactions (when reporting at consolidated level, you would want to exclude transactions happening between different entities of the same organization).
For both these issues, there are various options in BW (as well as outside, eg MDM for master data).
This is not to say that this is all that is going to be there.
If XI indeed uses XML only (or even if it is another format, essentially it is message based where one message shall contain a limited no of data), it will not be good to do the bulk load. The way it will likely happen is you will do historic data loads direct from source systems to BW, and then can link up through XI (or directly as well, depending whether XI really makes sense in your scenario) to get the delta data fed to BW.
cheers,
