Issue with screen varient creation

Hi Experts,

After EHP 7 up-gradation we have been lost the screen variant configuration button in FB50 and FB60 transaction codes.

Here my requirement is to define the screen variant with fields changes and we need to drag and drop the certain fields according to user requirement.

and we have the SHD0 transaction code to create the screen variant and we have been tried to drag and drop the fields according to user requirement but we couldn't able to drag and drop the fields.

Is there any possible way to change the fields in screen variant(SHD0)?

Regards,

Babu
