Hi Experts

We are creating sales order through IDOC and for creating SO we are using BAPI_SALESORDER_CREATEFROMDAT2 but idoc is getting failed with error

' Internal error: 10 , 000010 , NOT_ALL_INPUT_DATA_PROCESSED '

Not able to understand when this error comes. Please letme know what is the issue?

Thanks,

Amit
