ZMDT add project not possible

Hello,

in our solman 7.1 sp10 we cannot add a project for transaction type ZMDT (SMDT copy). The However, it is possible to add a project when using ZINC (SMIN copy). I am logged in with the business role ZSOLMANPRO. See attachment and everything will be clear

Could someone assist us on this?

Thanks!

Regards,
Kenny
