How can I get WorkItemCreationTime to BOR?

hi all,

i searched the forum and haven't got a proper solution for this.

i have a scenario where the task needs to be escalated to the next approver. the problem here is that i am storing the escalation periods in a customising table and this is configurable by the end user.

so, i thought of a solution of passing this as an expression and i have tried it by passing the <b>workitemcreationtime</b> and <b>date</b> through the <b>bor</b> to the function module. i tried to pass these values but i am unable to do it.

could you suggest a way to do this? or if you have any other suggestion than passing through bor, please advice me.

thanks and regards,
