Addition of field in change pointer entries.

Hi Experts,

There is requirement to add new field in change pointer so that IDOC can be generated.

I am facing problem to add field SPTXT from table T002T where material as object.

Can you tell how can I add SPTXT -language field in change pointer entires, so that Whenever there is change in material master for language field, for this field IDOC can be generated and reflected to external system.

Thanks a lot.
