Error in BAPI PO Create activity

I am new to SAP BAPI and automating some use case over there, in one of my use cases I need to use SAP BAPI PO create activity.
I am facing the below issue while running the activity,

“message”: “Execution stopped unexpectedly : \nMessage:Element Column1 of container metadata unknown \nStackTrace: at SAP.Middleware.Connector.RfcContainerMetadata1.NameToIndex(String elementName)\r\n at SAP.Middleware.Connector.RfcDataContainer1.SetValue(String name, Object value)\r\n at UiPath.SAP.BAPI.ConnectionService.SapConnectionService.SapConnectionService.SetInputParams(ICollection1 dataTables, IList1 arguments, IRfcFunction function)\r\n at UiPath.SAP.BAPI.ConnectionService.SapConnectionService.SapConnectionService.ExecuteApi(String apiName, ICollection1 dataTables)\r\n at UiPath.SAP.BAPI.Activities.InvokeSapBapi.<>c__DisplayClass26_0.<Execute>b__0(SapBapiTelemetryOperation operation)\r\n at UiPath.SAP.BAPI.Telemetry.TelemetryServiceBase.Operation[T](String operationName, String activityId, Func2 method, String bapiName)\r\n at UiPath.SAP.BAPI.Activities.InvokeSapBapi.Execute(CodeActivityContext context)”,

Any suggestion on this ?


Hello Debartha,
I assume you want to invoke from SAP Purchase Order the BAPI function module BAPI_PO_CREATE or BAPI_PO_CREATE1. Neither BAPI_PO_CREATE nor BAPI_PO_CREATE1 contains a parameter with the name Column1. I assume the name of the parameter is wrong and that could be the reason for this kind of error.
Let us know your results.
Best regards

yes, I am using BAPI_PO_CREATE1 to create purchase order, right now I am extracting data from excel to generate input for this function module, can you please tell me where can I see the parameter of this module ? I am new in this so I have little knowledge


Hello Debartha,
open TAC SE37 and type BAPI_PO_CREATE1 into the FM field.


Press display button and choose Import, Export or Tables tab.

Here you can find any parameter of the function module. With a double click in the Associated Type you can jump forward to the structure or variable definition.

Alternatively you can use the RFMCodeGenerator to get this kind of information.

Best regards
