SAP Hybris Cloud for customer Custom solution scoping is not enabled?

Hi All,

We have referred the SAP Cloud Application Studio help documentation Administration and lifecycle management.

We have created custom solution, BAC element. Activated, Assembled and downloaded the zip file successfully from test tenant.

We have uploaded the same in production tenant and activated in implementation manager in cloud application studio.

However, in Scoping/fine tuning the question entered under BAC element is shown as "Do you want to activate the custom solution" but the option to select is disabled. We are unable to enable the custom solution in scoping?

Can you please provide some pointers to fix this as we are unable to activate our custom solution deployed in production tenant?

Thanks and Regards,

Gauri
