How to process reports with two different date fields

Question

Morning all,
This question is somewhat similar to what I asked few days back. I created two different reports for two different departments (Credit Control and Free of Charge Control).
These two reports pull data from two different date fields and has different status check ups.
Few days back my director requested me if he can have both reports in one report. That is when I asked question from all of you regarding two reports.
Anyhow, that was created by implementing two sub reports however, the director asked me to combine the two different reports into one in such a way that the output records should be added up with each other hence one single report with all combined data of Credit Control and Free of Charges (not two sub reports in one report).
The problem here which I am getting is that, both reports uses two different date fields. I can live with two different statuses as that can be easily done within formula/RT however how to create a report with Report Selection Formula condition which looks in both date fields and produces results accordingly?
I have tried this by not putting any condition in report selection formula and ran the report, it produced total results from past 6 years.
Any ideas how to produce combined report which has two different date fields?
Many thanks in advance

Answer 1

Charliy,
No the both dates are from two different databases, tables and fields. The Credit date field is from KLAB database under max table where as the FOC date field is from SAE database under maxmast table. Klab date is under credit2 table where as foc date is under order header table.
So its more like this:
Klab->Max-Credit2--->Credit_date
Sae->Maxmast->Order_header---Date entered.
two dates totally different tables, dbs
however, I will try your idea too and see if that works.
