I've made a Workflow (by SPD 2010) where I calculate differences between 2 days. When I run this workflow once for 1 Doc.Library item, it calculate it right. BUT when I use Sheduled running WF to all items in library, this calculating get only 0.
In calcultating I use : Find days between CI:column and variable:Today (output to variable:days)
I use at shedule HarePoint Workflow Scheduler program Target is Document library
Single run WF result days = 1334,04 Sheduled running for all items in Library Days = 0
