@Dmitry Masanov I don't see

customersubof

as a valid Filter in the Records Browser, but my guess is that it's a List field, so you should be using

ANYOF

, not

IS

. Also in case your variable name did not change between versions, you have

customerID

in one and

customerId

in the other.

Thanks @erictgrubaugh. Yes, looks like customersubof is not a standard filter, but it was chosen on "Available Filters" subtab. I tried ANYOF as well, but still no luck.

The field label and the script id are not necessarily the same; it's possible you just need to scan the Records Browser for the right ID

Hm. I actually found search filter customersubof select Customer Sub of here: https://www.netsuite.com/help/helpcenter/en_US/srbrowser/Browser2018_1/script/record/transaction.html

aside: You may want to start using

2020_1

instead

Yes, saved search is a Transaction search. Just checked 2020_1 and looks like customersubof is still there

Three things to always check when you get that

is not in proper syntax

error: 1. Is your Filter ID valid? 2. Does your Operator match the Field Type? (

Help:SuiteScript 1.0 Search Operators

, equally applicable to 2.x) 3. Is your value correct?
