Symptom
For example While entering time in time sheet you enter with UOM hours also in the project the UOM is hours, but in Purchase order and in Material master data, the UOM is Wdays.
However you expect system to pick the UOM in Invoice from the Purchase order where UOM is Unit of measure.
Environment
SAP Business ByDesign
Resolution
This is expected behaviour in any Purchase order and Supplier invoice that has goods receipt created (time recording will generate auto GSR)with different UOM.
Of course if no Goods receipt exists and if you create invoice then the UOM in Invoice will be same as Purchase order.
