I've been digging through SuiteAnswer articles all morning and cant seem to find the right search query for what I am looking for. How do I find the ID of the sublist? I have a custom record (Monthly Usage - customrecord_monthlyusage) that is linked to a custom transaction. I want to display the usage on the Custom Transaction's Advanced PDF Template but all I can find is:

<#list record.item as item>

I tried:

<#list record.customrecord_monthlyusage as item>
<#list record.customrecord_monthlyusage as usage>
<#list record.custrecord_linktotransaction as usage> (this is the field that joins the custom record to the custom transaction)

all without success.

How is the custom record linked to the transaction? Are you using a custom field on the transaction?

no, it's a sublist. Field on the Custom Record with Record is Parent = T

I find looking at the record xml helpful. Add &xml=t to the record url on view form.

You will likely find it's prefixed with "recmach" like this: "recmachcustrecord_deprhistjournal" as mentioned above you can see this with &xml=T or right clicking the sublist and inspecting the source which may be more arduous.
