Hi everyone!. I´m from Argentina and 1)thanks for helping
2)sorry for my english! 
I need to learn how to use a logical formula in SHEET A to copy an entire line to SHEET B, if one of the columns of the line to be copied has a "R" status ("R" from "restriction" that line has)
When entire line appears in SHEET B, I need to process/edit it to change "R" status to "OK" status. When this new status changes in SHEET B, I need to delete "R" status in SHEET A.
So my formulas have to be something like:
1) IN SHEET A: =IF "R"; copy entire line to SHEET B
2) IN SHEET B: =IF "R" changes to "OK" then DELETE "R" from SHEET A
I´m working on construction management, in a template for LAST PLANNER SYSTEM...a methodology for LEAN CONSTRUCTION...so restrictions in activities are very important to define and resolve...
Thanks again...waiting for some help! in...3...2...1....
