Planning Book Selection window showing just one characteristic

Hi Experts,

Assigned all characteristics of DP planning object structure to planning book. All characteristics (product, location, customer, etc.) are appearing to choose from in show field & also in object selection window.

Say Product is chosen in show field, and plant is further chosen as selection criteria. On loading the selection only product field is appearing with 5 fields for product characteristic. By choosing selection fields able to show just one field for Product characteristic.

But don't see any option to display other characteristics like location, customer, etc. How to show them? Screen shot attached.

Thanks,

Bijit
