CR2008 Purchasing Report needed

Question

Hi
Has anyone created a Purchasing report in Crystal Reports 2008 based on AP Invoices and AP Credit Notes. I have created a WPA (Weekly Purchase Analysis) report but based off AP Invoice table (OPCH & PCH1), now the company is wanting to have Credit Notes added to this report.
I have created a UDF called WPA on the OPCH form which is a Mandatory field so when running the WPA Report you can run it by WPA # and Project to get your results (Parameter), now how will I acheive this by adding the AP Credit Note fields ORPC & RPC1 to the report so if I create x2 Invoice's (different suppliers) for say WPA # 1010 and I Credit one, on the WPA Report I will want to see Invoice 1 (NumCard = 1) = R100, Invoice 2 (NumCard = 2) = 100, Credit Note 1 (NumCard = 2) = -100, Total = 100.
Any suggestions or ideas will be most helpful.

Hi Kurt,
That is possible using "Shared Variable".
Check this link: [Sub-report data in report|Sub-report data in report].
1.Initialize a shared variable in Report.
2.Pass the Credit memo value to the 'Shared variable' in Sub-report
3.Now create a formula in Report like
      Sub-total = {Invoice total} - {SharedVariable}
In order to know more about shared variable, post a separate question in [SAP Crystal Reports Design - Forum|SAP Crystal Reports;.
Hope this helps.
