Accessing fields in Table Extension

(0) ShareShare
ReportReport
Posted on by lsp_612 5

Hi,

I am new to D365FO and this may seem like a silly question. However, any help will be highly appreciated.

I have an extension for base SalesTable, let's say, 'SalesTable.MyExtension' to which I have added few custom string fields. Ex: ReferenceID, DeliveryType etc.

Now if I want to access them from my X++ Code, how do we do that?

SalesTable salestbl;

salestbl.SalesID; => VALID

SalesTable.MyExtension salestblextension; => Throws error

salestblextension.ReferenceID; => INVALID

The error is  "The name SalesTable.MyExtension does not denote a class, a table or an extended data type".

If I need to use the value in my custom fields in a class, how can it be accessed?

Any help is highly appreciated. Please excuse my amateurishness.

Thanks.

    The extension is applied to the base object in runtime. So you access the fields via SalesTable.MyNewField.

    Hi Isp,

    As Nikolaos said,You just need to call with the original table buff.
    For example, when you create an extension class, you can use it as follows:

    [ExtensionOf(tableStr(SalesTable))]
final class SalesTable_Extension
{
    public static boolean isMyFieldEmpty(SalesTable _this)
    {
        return _this.ReferenceID == '' ? true : false;
    }
 
}

    I think you are missing a model reference.

    To elaborate on Bharath's answer, the packages in X++ are like C# DLLs - you need to reference them correctly.

    SalesTable is in AppSuite. Your extension is in "MyExtension". At this point, only code that lives in "MyExtension" can see your new field.

    From another package, you can reference "MyExtension" - then you would see the field there too.

    Note that you can't go circular of course. So if MyExtension is referencing AppSuite, then AppSuite cannot reference MyExtension - implying AppSuite code can never see your new field.

    Hope that makes sense.
