Truncate reference field variable for short description

[JuliaHowells]

On a record producer, we have a reference field that looks at the cmn_location table for Accounts. 

On submission, I want to set the short description to: 

current.short_description = producer.account: 'Order Number: ' + producer.u_order_number + ' - Postal/Zip Code: ' + producer.u_zip_code;

However, the account name needs to be truncated to 30 characters. How can I achieve this?

Hi Julia,

If you are already getting the display value for producer.account, you should be able to limit it by using producer.account.substring(0,30);  If that gets funky results then producer.account.getDisplayValue().substring(0,30).
