UOM question

Good morning all,

I have a question about why same UOM get displayed differently in InfoObject and cube. For example: Transaction - SPRO

Unit of Measurement of Dimension Overview table

Unit Commercial Technical Meas. Unit Text

BOX BX BX BOX

In one our InfoObject, I have an attribute Primary UOM which reference 0UNIT. It displays BX. When I load the trasactional data, the 0BASE_UOM displays as BOX. Can anyone tell me why is it different?

Thanks!
