HI Venkat,
I haven't traced the table it gets populated in. I'm using a Function module to create this, so it's mostly just structures that I see.
call function 'BBP_PD_CTR_CREATE'
exporting
* I_PARK = 'X'
i_save = 'X'
i_header = ls_header
it_conditions = lt_condition
importing
e_header = ls_eheader
tables
i_item = lt_item
i_partner = lt_partner
i_orgdata = lt_orgdata
e_messages = lt_messages.
