B2B order is not created in R/3 system

Hi,

Order createdn in B2B,but did not get through to gSAP(R/3) due to an error.

In CRM error is showing like this.

Error : Partner with the partner role AP cannot be converted (Notification E C( 010)

I've checked Bdocs,inbound/outbound queues also, there is no error.

Could you plz help me what is the root cause of this issue.
