Enhancement spot in BAPI_MATERIAL_SAVEDATA

Hi Experts,

I have a requirement to enhance the BAPI_MATERIAL_SAVEDATA to trigger when creating/changing (MM01/MM02) materials.

I have done it in Development System and working fine. but when i moved to Testing System (QA) it will not even trigger my enhancement.

I activated the enhancement spot in Testing system again and checked. its not working.

Could you please give me an idea.

Thanks,

Chaminda
