Ax2009 - Missed FilterByField and FilterBySelection on some grid columns

[ist]

Hi, everyone,

I have a form with two dtasources - InventTable and CustVendExternalItem. CustVendExternalItem datasource has joined with the InventTable datasource as JoingMode = OutherJoin. The problem is that FilterByField and FilterBySelection are not appear in the context menu for the fields from CustVendExternalItem. I have the same form in Ax40 SP1, but the problem does not exist.

Is there any way to display this elements on the context menu on the this fields in ax 2009?

Regards,
ist.
