Transfer Field from GLTran to PMTran

You need to create a graph extension based on an existing extension called JournalEntryProjectExt, which is located in the PX.Objects.PM.GraphExtensions namespace. After this, you need to override the InsertProjectTransaction method.

public class JournalEntryProjectExtExt : PXGraphExtension<JournalEntryProjectExt, JournalEntry>
{
    public static bool IsActive() => true;

    #region PXOverride
    public delegate PMTran InsertProjectTransactionDelegate(PMProject project, PMTask task, PMAccountGroup ag, Account acc, GLTran tran, APTran apTran, ARTran arTran);
    [PXOverride]
    public virtual PMTran InsertProjectTransaction(PMProject project, PMTask task, PMAccountGroup ag, Account acc, GLTran tran, APTran apTran, ARTran arTran, InsertProjectTransactionDelegate insertProject)
    {
        PMTran pmTran = insertProject(project, task, ag, acc, tran, apTran, arTran);
        if (pmTran != null)
        {
            //TODO: Add your custom logic here
        }
        return pmTran;
    }
    #endregion
}
