how do you get work order completion Date on the Saved search? I got the Work order closed date by using Date closed, but there is no date complete.

Depending on how complex the otehr stuff in the search is, you can join to the

Work Order Build

with

Applying Transaction Fields...

(and grab the date from that) and adding criteria of

Applying Link Type

is

Work Order Build

to make sure you dont get other joined transactions in there
