Block Until Done - cant figure out how to use

[craigja]

Hi,

I want to write to 3 separate tabs on an Excel sheet but cant as Alteryx tries to write to the Excel file simultaneously and it fails.  I see there is a Block tool but I dont see how I can get that to work in my workflow, can anybody suggest an alternative way?

Yeah Im sure it would work, but it means me removing a few of the tools them adding them back in a specific order in order to get the block until in the right place, thats why Im going to just use the union then block until to split back out
