Tcode SARA dump Exception condition "PARTNER_MISSING" raised.

Hi Experts,

I am using the Tcode SARA to archive business partners using the Contract Object but there is a dump "PARTNER_MISSING" in the method READ_PARTNER_DATA.

if i_partner is initial and i_partner_list[] is initial.

     raise partner_missing.       "#EC RAISE_OK

endif.

Could you please tell me how is(are) the partner(s) determined here?

Thanks,

Vitish.
