Your challenge is a bit of the reverse of [URL="http://www.monarchforums.com/showthread.php?t=3415"]this post[/URL] but a possible solution could be similar.
There aren't any options to prevent Monarch from running project exports if no data exists in a summary, so we need to tackle this another way.
If we run the export as a temporary file, or first stage test, then we can use the ouput from that test to determine what the next step should be.
You could build a special test model/project configured to have a summary that would not export headers, but would export only a single field from your data set, and only the value of that field in the first row in that set (see the matching tab in the summary definition). Define a project export to output to a control file, say "C:\Test\output.txt".
Using a batch file, load and run this test project. Now read that file into a DOS variable and if it's empty, don't run the real Export, but do run it if there's something in the test output.
Can you get there on your own by referencing the cited post above?
Ok, I think I understand what you're saying. I can create a summary for each project before hand and generate a text file with a single column, use a batch file to check if there is data in the text file, if there is than email, if not than skip.
How do I export a summary without a header? Have been unable to find this out.
