IBase component is not a production system in system landscape

Dear experts,

I am using Solman 7.1 SP 14.

I have successfully configured ZMMJ and can use this up until production.

I want to use the same project (which is working and has an open maintenance cycle and task list) for ZMHF. But on change creation i get the following:

I am sure it is not an authorization issue as I have SAP_ALL both in Solman and the managed system (which is also Solman as I am testing on DEV for now).

The error appears even before project and Ibase selection. The error does not dissappear after I select the correct project and Ibase.

Any suggestions?

Thanks,

Philip
