Create/Update classification data for the existing Material

Hello Friends,

Can any one worked on the below requirement.

how to Create/Update the Classification after creating a material?

BAPI_MATERIAL_SAVEDATA is used to create a material but cannot Create/Update the classification data.

I have looked into the following BAPIs.

BAPI_CHARACT_CREATE or BAPI_CHARACT_CHANGE. But these are not giving the desired result.

It would be of great help.

Thanks, Prakash.
