SAP CLM phase information page enhancement

Hello everyone,

I have a requirement to hide the workflow phase information page located under document system toolbar based on conditions for contract documents.

Please let me know if i there any option to hide it.

We are able to hide attachments page throwing error messages "not authorized" as there is a class available to code in the event. But for workflow phase information to write any piece of code. this is not exposed in scripting available classes. can we expose any class by our own to write code, please let m e know.

Any replies will be much appreciated.

Regards,

Narender.
