InitFrom

Often, a record has default values for fields initialized with data copied from
another table. For example, when a sales order is created and a customer account
is specified, fields including Invoice Account, Delivery Address, Tax Group, and
Currency are copied from the CustTable record to the SalesTable. This is done
in the SalesTable.InitFromCustTable() method which contains a list of field
assignments between the two tables. This is a common technique of initializing
fields in one table from another table, and is always the first place to analyze.
For example, to add the new field "Fragile" to the BOM table that defaults from
another new field "Fragile" in the InventTable, consider adding the following
line to BOM.InitFromInventTable() :

1	this.fragile = inventTable.fragile;
