Hello everyone,

We have a main custom object (Expense_c) with a secondary object (Resource) related by a DCL (OraZcxOwner_c) from which we want to recover a field value (OraZcxOwner_c?.PersonLastName) and set it in a field of the main object (Expense_c?.CNT_GST_Descripcion_c).

On the firsts attempts we tried to achieve this through this piece of code:

var expenseRow = getCurrentRow();
var owner = expenseRow.getColumn("OraZcxOwner_Obj_c");
