How to export metadata with member level security assignments

Hi All, We have EPBCS applications and are looking for guidance on how to export metadata for a dimension (such as Entity) with associated security group assignments included for each member. Our requirement is to produce an export that contains:

• each member of the Entity dimension
• the security groups assigned to that member
• the access level (Read, Write, etc)

Please advise if Oracle provides a method or export processes to retrieve this information in a single export or structured file format (eg. csv or excel), ideally aligning with standard EPM metadata exports.

Thanks,
Chareon
