Running a .FEX Program a Second Time Returns Old Data

If we run a .FEX program which prints data from a file, then we update the file using a Maintain program, and then run the .FEX program a second time, we get the old data, not the updated data.

The block of data from the first .FEX seems to stay in storage from 2 to 10 minutes depending upon other server activity.

Is they a way to force the second .FEX to go out to the file and get new data each time it is run?

We are on Developer Studio and Maintain 7.6.0 and a Windows server.

you are viewing your report via a browser, yes?
the browser is pulling the report from its cache, unless your force it to refresh.
position your mouse on the report output, click right, and click refresh.
Make sure your and your users browsers are set to dump their cache on exit and re-entry (tools/internet options)
the standard way to prevent this from happening *ever* it to use a random variable as a parameter in your fex. from the fex's launch page, the random variable in the form prevents the url of the page from being exactly the same as anything run previously and therefore stored in cache.

The way to do this is to pass a timestamp to the focexec. You want to create a random value and display it on the screen out of site. Then pass that value to the exec. Remember to perform this case everytime you update the database.

Case UpdateStamp
TIMESTAMP/D8.2 = RDUNIF(TIMESTAMP) * 100000;
Endcase

How are you performing the external procedure? If you are using a weblink pass this value to the external procedure. If you are using EXEC, pass the value as well.

Thanks Mark and Susannah. I needed to pass the random value in a MRE Web link. It is working fine now.
Thanks again.
