Hide an element from the combo box

Question
I have an enum with values Element1, Element2 and Element3. Now this enum is being used on two different locations what the requirement is that i have to add another element Element4 in to the enum but this should only reflect on one location.

Answer
Let say you you two forms where this enum is reflected, namely Form1 and Form2. In order to hide an element from Form1 and continue showing it on Form2 go to form design and then access that combo box control. Override the enter() method of that combo box and write this line to delete the element from it.

combobox:enter()
{
super();
this.delete(enum2str(BaseEnum::Element4));
}

Posting in the General Ledger (GL)

Question:
How to create a posting entry in General Ledger (GL) module of Dynamics AX?

Answer:
There are many ways to create posting entries in to General Ledger module. In my experience the simplest way is to use the Journal classes. There are two parts of posting create a heade entry and then create the add lines to it. To create a header entry use the LedgerJournalTable table and use the LedgerJournalTrans table. Finally use the ledgerJournalCheckPost class object to post these entries into the system.
Below is a job explaing the Posting process in a simple way.

static void postVoucherThroughJournal(Args _args)
{
Dialog dialog = new Dialog("Ledger Posting Example");
DialogField ledgerAccountField;
DialogField offsetAccountField;
DialogField ledgerJournalDescription;
DialogField ledgerAmount;
DialogField ledgerTransDescription;

LedgerJournalTable ledgerJournalTable;
LedgerJournalTrans ledgerJournalTrans;
LedgerJournalCheckPost ledgerJournalCheckPost;
NumberSeq numberSeq;
;
dialog.addGroup("Post Ledger Voucher");
//Add Fields
ledgerAccountField = dialog.addField(typeid(LedgerAccount), "Ledger Account");
offsetAccountField = dialog.addField(typeid(LedgerAccount), "Offset Account");
ledgerJournalDescription = dialog.addField(typeid(Name), "Journal Name");
ledgerAmount = dialog.addField(typeid(AmountCurDebit), "Debit Amount");
ledgerTransDescription = dialog.addField(typeid(Name), "Transaction Text");

if(dialog.run())
{
ttsbegin;
//STEP1: INSERT Journal Header
ledgerJournalTable.JournalName = 'Day1'; /This is the journal name.
ledgerJournalTable.initFromLedgerJournalName();
ledgerJournalTable.Name = ledgerJournalDescription.value();

ledgerJournalTable.JournalNum = JournalTableData::newTable(ledgerJournalTable).nextJournalId();
ledgerJournalTable.insert();

//STEP2: INSERT Journal Details
numberSeq = NumberSeq::newGetVoucherFromCode(LedgerJournalName::find(ledgerJournalTable.JournalName).VoucherSeries);
ledgerJournalTrans.Voucher = numberSeq.voucher();
ledgerJournalTrans.JournalNum = ledgerJournalTable.JournalNum;
ledgerJournalTrans.CurrencyCode = CompanyInfo::standardCurrency();
ledgerJournalTrans.ExchRate = Currency::exchRate(ledgerJournalTrans.CurrencyCode);
ledgerJournalTrans.AccountNum = ledgerAccountField.value();
ledgerJournalTrans.AmountCurDebit = ledgerAmount.value();
ledgerJournalTrans.TransDate = Today();
ledgerJournalTrans.OffsetAccount = offsetAccountField.value();
ledgerJournalTrans.Txt = ledgerTransDescription.value();
ledgerJournalTrans.insert();
//Post Journal into Ledger Accounts
ledgerJournalCheckPost = LedgerJournalCheckPost::newLedgerJournalTable(ledgerJournalTable, NoYes::Yes);
ledgerJournalCheckPost.run();
ttscommit;
Info(StrFmt("Journal %1 is posted", ledgerJournalTable.JournalNum));
}
}
