Classification data not creating in MM01

Question

I am having a strange problem.
While creating a material using MM01, I select the views Basic Data1 & 2, purchasing, classification & accounting 1.
In the classification view, for class type 023 I enter a class, say ZCLASS.
After I hit enter, characterstics assigned to this class are displayed. I select the values for the characterstics & proceed with creating other views & save it. I select the batch managed check box in purchasing view as well before saving.
Now, when I go to MM02 or MM03 & display the classification data, theres nothing in there.
No class, no characterstics.
But if I enter the class ZCLASS again in MM02 for the material & save it and then display it, I can see the classification data.
I am wondering what is happening with the transaction MM01.
I have tried this with class type 001 as well but it didn't help.
Do I have to always go to MM02 after MM01 to have the purpose solved or can it be done directly the first time.
Would appreciate your help.

Mohan,
The first time you enter MM02 or MM03, you will typically have to choose which of the available Classes you wish to display (since there are many, and the system has no idea what you want to see).  Once you have selected this, the system will usually remember which one you looked at the last time, and will default to this for the next material that you change/display.  This behavior is standard.  Each time you log onto SAP, you will usually have to make this choice for the first MM02/MM03 you do each day.
I believe you are properly creating and saving your ZCLASS data during the MM01 session.  I believe that nothing is wrong.
The test is to immediately go from MM01 to MM03 and display the Classification view of the Material you just entered.  Enter the class.  If the data you just entered appears, then you are good to go.
