Spl gl indicator for "Advance from vendor" in F-29

Hi friends,

Our client needs "Down payment from vendor" to be booked in SAP system. Could you please suggest which Spl Gl indicator should be used for this in Tcode "F-29" .

Please note I'm asking spl gl indicator for down payment "from" vendor and not down payment "to" vendor . Could you please help...

Note: The same customer is used as vendor as well , So Tcode f-29 is been used..

Regards
