I americium presently trying to replicate MB5B. When I spell to method information for the idiosyncratic fields, I see
MBEW - Plant
MARA - Material, Base Unit of Measure
MSEG - Receipt, Issue, Current Quantities & Value
T001 - Currency 

However successful doing immoderate probe online, I saw this post: https://community.sap.com/t5/enterprise-resource-planning-q-a/mb5b-tables-for-se16-download/qaq-p/77...
