You can use a Tester or TestFilter before the WorkspaceRunner.

Thanks but you can imagine i tried it before without successing

Where are the attributes to filter? You use only the Creator before the WorkspaceRunner. 

This is an excel file with  an attribute for each workspace Runner set to true or false

Lots of different ways.  Basic way of Prioritising and running a Workspace with a dynamic value for its Path below.

Sample Excel data.
 

Feeds into a Prioritisation using Eg. Sorter and Sampler.
 

Great ! works perfectly

Thanks a lot

i completed with :

• ‘tester’ for run = 1

• set sampling Rate (N) to the max of ‘controle’
• included user parameters in to workspace (even if few of the 10 .fmw don’t need all)

Meaby an other way to do it but this one works

Thanks again

forgot this
