Error while sending standard PO

Hi All,

My Scenario is - SAP ERP to SAP PI (Data thru IDoc)

I have created standard PO but it is not sent to SAP PI. In SLG log of ERP i can see below two errors,

1) Environment parameter SVT_MATERIAL_CLASS has not been specified

2) Current document item is not relevant for regulation REACH

Not sure about what parameters need to be maintained and what configurations need to be checked. If you came across these type of errors kindly please share your knowledge in detail.

Thanks,

Tamil
