Access child custom record type from parent custom record type

Question

I've created a custom record type called PALLET as parent and a custom record type COMPONENT as child lines because it is one to many relationship. In another words, one PALLET can have multiple COMPONENTS. I can access PALLET from suitescript as below

function beforeSubmit(context) {
    var record = context.newRecord;
    record.setValue('custrecord166', '8888'); 
}

However, I cannot access COMPONENT from PALLET using suitescrpt and it return -1

function beforeSubmit(context) {
    var record = context.newRecord;
    var lineCount = record1.getLineCount({sublistId:"recmachcustomrecord_pallet_component"});
}

Any suggestion is welcome

Answer 1

the sublist id when referenced from a parent account is recmach+ the field id of the custom field on the child record with is tagged to the parent.

ie.

parent record = customrecordparent123 (Named "My Parent Record")

child record = customrecordchild123

on your child record, you will have a custom field of type list/record of type "My Parent Record".

This field will have "record is parent" ticked. Say this field's id is custrecordmylinkedparent.

when you reference the child record as part of a sublist, it will be sublistId:'recmachcustrecordmylinkedparent', referencing the child record field.

!! Remember, the recmach is not the parent record, but the linking field on the child record.
