How to use temporary files while using chained apps in Gallery?

anil_m

Hi,

I am using the chained app with three workflows.  Workflow_1 writes the data into %temp%..\Drivecam_All_States_1.yxdb.     and in Gallery settings, my temp directory is set to  "E:\ProgramData\Alteryx\Engine\", But my interface data in Wsorkflow_2  is not refreshing.

I have also tried like this. While writing "%Engine.TemFilePath%Drivecam_All_States_1.yxdb"   and while reading I have used the same "%Engine.TemFilePath%Drivecam_All_States_1.yxdb".

This is also not refreshing the data between two chained apps.

Can anyone please guide me on this?

It may be a quick spelling fix (missing the p in TempFilePath).  You should use the Engine.TempFilePath constant as %Engine.TempFilePath%, but then you need to specify that it's in that directory, so: %Engine.TempFilePath%\ to create %Engine.TempFilePath%\Drivecam_All_States_1.yxdb.

The reason that you can't just use E:\ProgramData\Alteryx\Engine\ is that Alteryx instantiates the workflow when it is run, so the Engine sub-folder (the folders with the random string of characters in the Engine folder) will not be the same each time.

Temp File help if you haven't seen it yet.
