Variant for Module Pool / Module pool transaction

Hi,

I want to create Variants for Module Pool.

So I added save option to the toolbar.

But it is not functioning properly. Sometimes it grays the variant name.

Also we have to click twice.

So i created transaction for the MP.

But still it is working the same.

Has anybody created variants for MP or MP transactions ?

Points will be rewarded for helpful answer.

Thanks in advance.

Regards

Megha
