GRC BRF+ Decision Table

Hi everyone.

I'm customizing a Decision Table in BRF+, i'm able to export it to a spreadsheet, edit and import it back, but when i try to save the changes i get a window pop up asking me for a transport/task, i created a Workbench transport in SE10 but it's not shown in the transport list, if i manually type the transport number and try to save the message says "Transport request or task GRSK900008 is invalid". The same thing if i try a Customizing Transport.

Any ideas?

Thank you for your time.
