PDH Manage Change Order search is not working

We are using Oracle PDH Cloud 23B . We have one custom view only role . Owner of that role is not able to conduct search for existing commercial change orders in 'Manage Change Order Page'. As this is a view only role , we are not supposed to assign any role like 'Product Common Management' to this role.

Please help me with exact privilege / Data security required to give Change Order Search access t for this role.

Thanks in advance.
