Date based report with multiple record return

Question

Hello all,
   Here is the situation. Running MAS 4.1 and using Crystal 10 for doing reports. I currently have a custom report that shows all invoices that have been paid for any given date range. This works great except when there is a "credit Memo" against an invoice. The way I'm getting all paid invoices is via a formula. The record set I have to pull against lists the invoice amount, date paid and amount paid. Simple calculation on the returned record will tell you if it has been paid off or not. The problem I'm having is those invoice records that also have a credit memo against them. The credit memo entries do not have a "paid date" and since that is my main selection criteria those records will not pull into my report, and therefor those invoices will not be showed as being paid. What I need to happen (and I don't know how to do it). Is for the report to run based upon the date range specified, and pull in related records even if there is no "paid date" on them. The way MAS stores it's invoice/credit memo records is the same for both. The main difference is that invoice has the "type" field set to "IN" and a credit memo has the "type" field set to "CM". So the actual "invoice number" is the same for both kinds of records. I hope my request makes sense, if not let me know and I will try to explain what does not make sense.  Thanks in advance.  Bill

Jason,
    You've been very helpful, but I guess I'm just not explaining myself that well. The Credit Memo's throw things off because they do not contain a "Paid Date" value. That field in the record is blank. Since it is blank the report query ignores them. Therefore when the report query returns all records that have a "Paid date" range of "x to y" they are never returned. This is a problem whenever a credit memo exists for an invoice because the "invoice total" never changes. So when a customer pays on their account for a particular invoice, they only pay what is due which is the "invoice total" minus any "credit" from the "Credit Memo". So when my A/R person receives payment they are showing the invoice paid in full because MAS automatically includes all invoices and credit memo's. My report does not because there is no data in the "Paid Date" field of the record for Credit Memos.
I've been doing alot research in trying to resolve this "exception" to my report. I think I may be on to something, but my knowledge of arrays is extremely limited. My resolution involves populating an array with the "invoice numbers" that are returned from the initial query from the supplied date range. Then using the "invoice numbers" from the array have it then populate my details section of the report with all of "invoice records" both the actual invoice record and any "credit memo" records. I can then group the records returned  based upon the "invoice number". then within that grouping I can performing my calculations to show whether or not the invoice has been paid in full. What do you think?  I've been able to populate an array with the invoice numbers based upon my date search range, but I have yet to figure out how to take that information and perform another lookup to pull in the rest of the data I need. Do you have any ideas?
Thanks.  Bill
