IF_EX_DOCUMENT_MAIN01

Hello experts,

I am trying to check the value of a characteristic when I save a document in CV01N/CV02N.

I am using  IF_EX_DOCUMENT_MAIN01~BEFORE_SAVE but I have no access to classification information.

I have seen that in the same implementation there is a method call BEFORE_SEARCH_DATA that has the classification data.

How can I acces that information??

Thanks in advance.
