Exit while changing Material in MM01 or MM02

Question

Hi gurus,
I’m having some doubts with implementing an exit concerning TR. MM01 and MM02
I run TR. MM01 or MM02 , enter a Material Number, choose a view, then choose tab “ sales: sales org. 1”. Every time that I change the field “X-distr.chain status” and “DChain-spec. status” with “Z1” ( client specific restriction that allows blockING a material) I want to put the same “Z1” but in tab “Purchasing” in field “Plant-sp.matl status”.
I’m using EXIT   MGA00001 Material Master (Industry): Checks and Enhancements
I can put the “Z1” in tab “Purchasing” field “Plant-sp.matl status” for a specific material number (MATNR), but my question is how can I confirm that the user choose a “Z1” for a specific MATNR ? I’m asking this because my code is triggered when the user push the save button, and at this time I don’t have any modification in the table so I need to be sure that the user put the Z1 for a specific material?
Can u help me with this ?
TAB: sales: sales org.
“X-distr.chain status” = MARA-MSTAV
  “DChain-spec. status” = MVKE-VMATA
TAB: Purchasing
“Plant-sp.matl status” = MARC – MMSTA
Best regards,

HI Miki
Could you let us know for what purpose you want to use classification, ex: Define the charesteristic for material etc.
As it has many functionalities.
For creating the material with classification view, in the material type Classification view should be activated.
Goto OMS2, Select the material type & click on details.
Check for the material type Classification view is selected or not.
Select it if not selected.
Before creating the material master you need to maintain the Characteristics using CT04 & Class using CL02 with Class type 001 - Material class
Assigning the Characteristics to the Class in CL02
Goto MM01, create the material master selecting the Classification view & maintain the class maintained & the Characteristic Values.
From the Classification screen in the material master:
When you create classification data, the system asks you to choose a class type in a dialog box. If necessary, you can change the class type on the following screen, where you assign the material to one or more classes. Entries are made in the Description, Status, and Icon fields automatically on the basis of the classes you have chosen. If you have assigned the material to more than one class, you can flag one of the classes as the standard class. You can then assign values to the characteristics. For example, if the characteristic is color, you can assign it the value blue
Save the material after maintaining all the views required.
