When CA Service Desk Manager (CA SDM) is configured and integrated with CA Open Space, you may run into a situation where a user who has an "Employee" based Access Type is unable to add attachments to a ticket while logged into Open Space. If they were to log into the Service Desk Manager web interface directly, the user does not have any issues. You will see a similar problem if a user with an Employee Access Type tries to use the Service Desk Manager Mobile Enabler application, which is integrated with CA Open Space.
There is a data partition constraint that is associated to the Employee Role that can cause a problem when attempting to use attachments in CA Open Space.
You can disable this data partition constraint in order to allow attachments to function correctly for Employee based Access Type users in CA Open Space:
Doing so will not have a negative effect to attachments directly in the Service Desk Manager web interface and will allow attachments in CA Open Space to function correctly.
**NOTE: It has been observed that after making this adjustment it may take several minutes for the change to reflect within CA Open Space as a result of caching. Please allow several minutes for the cache to refresh and then attachments should function in CA Open Space.
