Hi all,
We have outsourced developer working on this project.

I have some objects that I would NOT want them to touch in the Object Management Workbench (OMW).

Therefore, I'm trying to block these few particular users from checking out the object.

I have tried using OCM and set by Role but to no avail.
I have also tried using the Security Workbench but I do not see anything that I could use to set this.
I have also tried using OMC, but this application does not seem to be able to set it by object.

Do you all have any idea?

Here is an example:
User: ABC
Object: R55xx

Blocked ABC from checking out R55xx in OMW.

I am on E8.12, Oracle DB, SP8.96

Thanks in advance,
