Hi There,
I'm badly stuck in a situation where i'm trying to output filter results to multiple tabs in an excel workbook, which i name dynamically using the Output tool configuration. So, i use the first filter results to create an excel output and use block until done tool for to output further filter results. Below is a snapshot of my workflow and the error i receive( i have tried changing the output options to Overwrite File, Create new sheet, Drop file) but nothing seems to give me what i'm looking for.
Workflow


Also, my company doesn't allow me to install crew macros package so can't use Parallel block until done.
Please help as i have spent days figuring out what do i do 
TIA.
