I've block 3 tables

ti itm 001
td ilc 101
td inv 001

for inventory cycle count.

What I did was

change the last counting date to null (empty the value ).

But the finance could not Generate Cycle Counting Orders.
They are suppose to view tgbrg5501m000.
But when they key-in the warehouse (exp:W10) the windows tgbrg5501m000 closes.

What I suspect is I accidently changed the wrong row .
For example lcod for last counting date but I changed a different field.
Can anyone tell me what is the origin fields status so that I can do the blocking again.

Or do anyone have any idea why I can't Generate Cycle Counting Orders.
