Using the TM1 isUnderFed Cube Attribute
If you are using DQM and are using Cognos TM1 10.1.1 or above and Cognos BI 10.2 or above TM1 will perform server side zero suppression and it will become impossible for you to see unfed values in BI regardless of whether you zero suppress or not. By adding the isUnderFed attribute you are changing this default behavior for the cubes where you set the attribute to “T”.This attribute is also effective in Planning Analytics (aka Cognos TM1 11)
a) Log in to Architect > select a model; Under the model > Cubes> select a cube by double clicking
b) Select Edit from the Menu
c) Select Edit cube Attributes
d) Select Edit > Add new attribute
e) Enter name > IsUnderFed (case insensitive)
f) Select Text radio button and click ok
g) Add a T (for True) to any cubes that we should avoid TM1-side suppressing
h) Restart BI (not TM1) services for the change to take effect.
We recommend avoiding this if possible but there are times where adding extra feeder flags into your cube creates to much weight and this is a more appropriate solution.
