What is LedgerJournalFormTrans Class?

If you ever tried to modify the LedgerJournalTransDaily form (the Ledger Jourlan Lines form) you would notice a forest of X++ codes executed on every click, initializations, closing, fields modifications… etc. Of course this makes sense because this form is basically the backbone of financial transaction of this Dynamics AX, which in turn the backbone of all modules of Dynamics AX.

One of the common classes executed in this form is LedgerJournalFormTrans class. Basically this class controls the controls of any form where LedgerJournalTrans table is a datasource for that form. It simply controls the visibility, edibility and validity of most of the controls on that form based on the “status” of the current Ledger Journal Trans and Ledger Journal Table. Whenever a user fills data, reads data, and clicks buttons and menu buttons.. a call for a method in that class is executed to control the new write/read/event.

Actually LedgerJournalFormTrans is an important class of a series of extended classes. Those classes are like the following:

• JournalForm --> JournalFormTrans --> LedgerJournalFormTrans --> LedgerJournalFormTrans_Payment

• JournalForm --> JournalFormTable --> LedgerJournalFormTable 

I believe from the name you could tell what all of those classes are all about.
