bug in debugger

I recently wasted a number of hours chasing what I thought was a filter problem. It turns out to be a debugger problem. It occurred in version 4.0 (no service pack) and I duplicated it in 4.0 sp2.

Code in on prereport trigger:


SalesInvHeader.SETRANGE("Shortcut Dimension 1 Code",'SALES');
SalesCMHeader.SETRANGE("Shortcut Dimension 1 Code",'SALES');
SalesBuffer2.COPYFILTER("Posting Date",SalesInvHeader."Posting Date");
SalesBuffer2.COPYFILTER("Posting Date",SalesCMHeader."Posting Date");
SalesBuffer2.COPYFILTER("Sell-to Customer No.",SalesInvHeader."Sell-to Customer No.");
SalesBuffer2.COPYFILTER("Sell-to Customer No.",SalesCMHeader."Sell-to Customer No.");

I stepped through the code in the debugger, and view Global variables in the debugger with the Table Filter item expanded so that I can watch the filters as they are applied. From the display, it appears that on the COPYFILTER after the SETRANGE, the Posting Date filter gets placed in the Shortcut Dimension field.

The issue was confirmed by Microsoft support and reported to development.

This is an FYI. I had searched here for report debugger problems and did not find this.
