When using the form purchParmLine, there is a trick of saving the lines on PurchParmLine table.
Each entering the form, a new PurchParmLine is created, on a new recid, but it keep the last values each column on the last record.
I see that for the second time (and farther) I open that form, there are two rows on the database (for one row I see on grid), and when I close the form - there is only one record in database.
I need to know that concept. in order to link a new table to that record, with reference rec id (of PurchParmLine).
