How to read Business Partner's E-mail ID from Memory/buffer

Hi,

my requirement is to capture the business partner's E-mail ID when I enter at GUI level.

I have checked the BADI BUPA_ADDR_CHECK, here I am getting the E-mail ID which is maintained under Independent Communication data. But when I maintain E-mail ID under Communication Dependent in tcode BP same BADI is getting called but not able capturing the e-mail ID.

Could you please let me know is there any other BADI or FMs to read the BPs e-mail ID from memory/buffer.

Thanks &Regards
