1. Navigate to Upstream SR
2. filter and select more than one Material say ('H000004321', 'H000005088')
3. Select the material H000005088 and change UOM say to KG
4. Navigate to SKU H000004321, the UOM in the dropdown will display the default value since UOM is not changed for this SKU (for this instance TB)

Actual: in the UOM field in PIR, KG is displayed but in dropdown, default value (EA) is displayed. refer attached snapshot 'Multiple SKU - UOM value in dropdown.png'
