Long text to be inserted for already maintained inspection plan through any recording

Hi,

     I have already completed maintaining inspection plan through LSMW recording.

     But MIC long text maintenance was not possible through that LSMW.

     Now Kindly suggest me how to maintain MIC long text in mass for all materials.

     Also for different materials Particular MIC long text is different.

     As the data is more, need some useful recording method.
