Whether basic data, company code data or purchase org data is changed for vendor...

Hi,

I need to develop a logic for an IDoc where in I need to find out if the basic data of vendor is changed, or is it company code level data or the purchase org data. There could be the cases where all of three gets changed.

I found a BAdi for it 'VENDOR_ADD_DATA' but it is importing activity as 'V' only for any kind of change due to which I am not able to recognize that which change was made.

Could you please help me with this?

Thanks in Advance.

Regards,
