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));
}
}

Display method in code

Scenario: Can i use display methods in X++ code. I mean if i have a display method getStatus() on table Vend. I can use it like vend.getStatus(). Is it a violation of best practice what are the pros and cons.

Answer: No, there is no performance penalty and no best practice warning is issued.
So you can go ahead and use the display methods in code.
The only difference from a non-display method is that you can actually use them in forms and reports.

Snippet:
Add as display method getStatus() in the CustTabl method list.

public display boolean getStatus()
{
return true;
}

Use this method in the field group and in the code simultaneously.

public void processCustomerStatus()
{
if (this.getStatus())
{
this.write();
}
else
{
info("Consider status");
}
}
