BAPI_INSPOPER_RECORDRESULTS call from external

Hello,

when I call the BAPI BAPI_INSPOPER_RECORDRESULTS to store the data, I don't get an error but the data will also not appear in the transaction QE51N...

Is there something special to do when I call the BAPI not from a report ?

I created a C# application and fill all values with the BAPI BAPI_INSPOPER_GETDETAIL first and then call the

BAPI_INSPOPER_RECORDRESULTS to store the data...but they are not stored...

Any idea what may be wrong ?

Thanks and regards

Michael
