DataReservationMode property

OFF

Turns off the Data Reservation feature for the specific cube.

The default value is OFF.

REQUIRED

Sets the Data Reservation feature to REQUIRED mode for a specific cube.

This mode disables write access for all users for the entire cube and requires you to explicitly assign Data Reservations for any user that needs to write to this cube.

For example, a user must have a Data Reservation on a cell if they want to write to that cell.

REQUIREDSHARED

Sets the Data Reservation feature to REQUIREDSHARED mode for a specific cube.

This mode is a variation of the REQUIRED mode that allows Data Reservations for different users to overlap. All other aspects of this mode behave the same as REQUIRED mode.

REQUIREDSHARED mode was implemented to accommodate overlapping requests leveraging multi-node edit capability in IBM Cognos TM1 Applications. This mode is the default assigned DR mode on all cubes represented by Cube Views or Manual Dependencies in TM1 Applications.

In REQUIRED mode, the TM1 server restricts write access to a slice by only allowing a single user to have a reservation for a node at any one time. In REQUIREDSHARED mode the application must enforce this restriction if necessary.

ALLOWED

Sets the Data Reservation feature to ALLOWED mode for a specific cube.

This mode maintains write access, based on security, for all users across the entire cube, but allows you to selectively restrict write access to an area of the cube by assigning Data Reservations to individual users as needed.

For example, ALLOWED mode lets you use Data Reservation to set aside a section of a cube for a specific user while keeping write access available for all other users to the rest of the cube.
