How to get Shipment block reason and output type without enhancing 2lis_12_vcitm

Hi Guys,

I am trying to get Shipment block reason and output type without enhancing 2lis_12_vcitm, but not have clear idea.

Tried creating new extractor with getting shipment block reason code alone from table LIKP-TRSPG. But it will be one field extractor....

But not able to get the output type (ex. Yval) as its related to customer specific.While checking its from structure DNAST-KSCHL.

Thanks,

RR
