create display method on table extension in Dynamics 365 AX

Create Display method in D365 for operations

Add a method in the standard table, it can be achieved either by creating a table extension.

So in this scenario we had a requirement to add a display method in the standard table "CustTrans".

It can be achieved by using the extension class.

Step 1: Create a new class and name it as <Classname>_<Extension>.

<Class-name> - can be any name, but it is preferred to give the table name for which the extension is being created. 

postfix <_Extension> is must.

public static class CustTrans_Extension

{

}

Step 2 : Now add the display methods in the class which is required to be shown.

public static class CustTrans_Extension

{

[SysClientCacheDataMethodAttribute(true)]

public static display AgreementId agreementId(CustTrans _this)

{

LedgerJournalTrans ledgerJournalTrans;

select ledgerJournalTrans
where ledgerJournalTrans.TransactionType == LedgerTransType::Payment &&
LedgerJournalTrans.CustTransId == _this.RecId;

return ledgerJournalTrans.AgreementId;

}

}

Step 3: To use this display method in the form.

Create a string control in the form design and set the following properties

Data source: CustTrans

DataMethod: CustTrans_Extension::agreementId

CacheDataMethod: Yes

Below is the screen shot for reference.

Step 4: Build/Rebuild the project/solution and check the output in the URL.
