vendor down payment list

Hi

Sap Guru's

In my company client want report i have seen in google also, but i didn't get proper information, he is asking each vendor wise down payment list along with PO number, posting date, amount and also with spl gl indicator. I have seen in BASK table level, at table level when i give Spl GL ind, it's not picking total line items comparing with PO history, And in the next step i remove Spl GL Ind, and given PO number then it's picking. Why all line items not coming comparing PO history by giving Spl GL Ind, is there any other way kindly give me suggestions

Regards,

Ramesh
