Context based adaptation not working for Material Master

Hi Sdners,

I am trying to create a adaptation where based on Material Type ( ROH) I am trying to hide Purchasing tab and change the UIBB name for Sales.

Scenario is User will Click on Create Material -> Enter Material No.  and Select CR Type

User will be directed to Material Create screen.

Here in Basic data user will select Material Type  = ROH,

Ideally based on adaptation Purchasing tab should disappear but it is not.

Adaptations are not working.

I am wondering when does adaptation trigger i.e. when user select material type (ROH) and hit enter during this time?

Kindly help ,its quite urgent.

Regards,

Neethu Joy
