Hi ganesh,

Please look at the SAP note 376424 - BAPI_PO_CREATE1: Error messages for parked POs.

Sap recommends to install the support service pack. Take a look at the note for detailed understanding.

Also take a look at SAP NOte

767284 - SE518 occurs although account assignment is supplied to BAPI (this requires Note 552114 must be applied as a prerequisite)

Consider contacting basis team after your analysis about the issue.

Regards,

Sivaganesh

Hi Ganesh,

please see once SAP Note 1020306 too.

Re: How to create service PO while using BAPI

Former Member — Mon, 02 Jun 2014 06:17:37 GMT

For this error,

Check SAP Note 767284 (Note 552114 must also be applied as a prerequisite)
