Just wanted to confirm once. Have a UE after submit script1 deployed on a record. Script loads the record updates a field and save the record. Have another UE after submit script2 deployed on the same record. Will the script2 pickup the new value in after submit or the old value?

The old value, probably. The first UE will never trigger the second

That's what I always assumed as well but since both are deployed on the same record. It's taking the new value. Script 1 was changing the shipping address on a purchase order. Script 2 was fetching the shipping address for some other purpose, and it took the new value. Maybe it's because shipping address is a subrecord.

Could be a race, depending on the order the scripts are deployed in and the timing of when they execute, the new value might get set before the second script runs

Could be, need to do a bit more testing, before I can be sure of anything.

Could the address update be relocated to

beforeSubmit

?
