MM02 - Enable options change number, change overview and change documents

Question

I am with the following problem: I enter the transaction MM02, I enter the material 1000765, I select the view "Classification". Later I access the environment option from the menu bar and options for change number, change overwiew and change documents are disabled.
How do I enable these options change number, change overview and change documents?

Hi Sergio,
If we activate the change documents for classification data, then we will be able to see the CHANGE DOCUMENTS for characteristic values through CL20N transaction (CL20N via menu ENVIRONMENT --> Change Documents) or MM02.
For reference please check SAP Note 65124.
For enabling change documents for classification data in SPRO --> Cross-Application Components --> Classification System --> Classes --> Maintain Object Types and Class Types.
In this enter into MARA table entry. Inside that corresponding to the respective CLASS TYPE (say 001) enable the CHANGE DOCS check box in Classifications part (For enabling this please check SAP Note 65124). Then for this CLASS TYPE (say 001) inside the OBJECTS folder, enable the CHANGE DOCS CLASS checkbox also.
Now in MM02 and in CL20N under menu Environment --> Change Documents you can view all the changes done to that characteristic values.
Once the change documents is activated, then we can get the change documents details in CDHDR and CDPOS tables. The OBJECTCLAS may be "CLASSIFY". We can also use the "CLLA_CHANGE_DOC_CLASSIFICATION" function module to fetch the data from these tables.
Hope this helps in solving your issue.
