Adding a new Navigational Attribute in DP

Hello Experts,

Can you please guide me the steps for adding a new Navigational Attribute from scratch in Demand planning. The new Z Navigational attribute is a field used in Material Master in ECC & it would be updated by Z program in SCM (those changes are know).

We need new Nav. Attribute to be seen in all cubes, planning book shuffler & in MC62 display screen. Right now we see all Nav. Attributes in all three places as mentioned above.

Please help me in details, what steps are to be followed.

Regards

Rahul Chitte
