Unactive transfer masks icon in mask manager toolbar

I wanted to follow a tutorial about the statistical function of SNAP.
Using mask manager toolbar in SNAP 6.0, I created a new mask but I was unable to transfer the selected masks since the “Transfer the selected mask(s) to other products” icon remain inactive.
How can I make that icon to an active one?

Best regards,


It depends how you have created the masks.
If you used a range, the same band must exist in the other product. If you have created the mask by an expression, the expression must be applicable on the other product. If a geometry is used for the mask, it can’t be transferred at all at the moment.
And you need to have at least one other product open.
