Ax2012 - How to Get Next Journal Number from C# via Interop Proxy

(0) ShareShare

Posted on by Community Member

Can anyone explain how to access the next Journal Number via class JournalTableData's nextJournalId() method?
In X++, the call looks like this:
this.JournalNum = JournalTableData::newTable(this).nextJournalId();

Since nextJournalId is not static, I have to create a JournalTableData instance and call JournalTableData.newTable() method.

C#:

myJournalDTO.Number = JournalTableData.newTable(null).nextJournalId();

I'm not sure what to do for the required parameter to newTable of a JournalTableMap.  The above gives a run time exception: {"Buffer not specified for call of JournalStatic::construct"} System.Exception {Microsoft.Dynamics.AX.ManagedInterop.ErrorException}

 I tried to create a JournalTableMap next, but same exception.  Looking at X++, it seem the parameter, while a JournalTableMap also accepted "this" which is a LedgerJournal Table.  I am unable to Cast LedgerJournalTable proxy into JournalTableMap... So Confused...

Any help is appriciated.

Thanks,

Joe

    I'm not aware of any way how to do it in .NET. JournalTableMap proxy class is not related to LedgerJournalTable in any way.

    But you can easily convert LedgerJournalTable to JournalTableMap in X++ by simple assignment. You could simply write a method accepting LedgerJournalTable and returning JournalTableMap. But more useful would be to add another factory method to JournalTableData acception Common, use SysDictTable::isTableMapped() to validate the parameter and call JournalTableData::newTable().

    I did not need to mess around with the class and tablemap in .NET.  I justed ended up adding a method to LedgerJournalTable to get, assign, and return the next journal id (similar to how insert() does it.).

    public LedgerJournalId getNextJournalNum()
    {
        ;

        this.JournalNum = JournalTableData::newTable(this).nextJournalId();
        return this.JournalNum;
    }
