vendor unknown

quantity contract is maintained for this material group(accont. ass. ca. is k) but no source list is maintained(as it is not possible for material group) and there is no info record either...............now when i use tcode me25

to create po for w/o material master that is for a material group and with account assignment category k

system is not able to search for the vendor or possible source although i have marked source dter. check box on intial screen

system displays message that possible source could not be found

so what can be reason for this
