Hi Rutvik,
We have registered 2 new Units of measure 2 KG, 5 KG
We registered new Product with 2 KG all units of measure
There are Inter class conversion factors between 2 KG - kg and 5 KG - kg
But to be able to use Unit of measure 5 KG in POS it is required also to register Intra class conversion between 2 KG and 5 KG
Then in POS you may use also 5 KG unit of measure
The same is for normal Sales order that there is 5 KG unit of measure available if there is defined Intra class conversion between 2 KG and 5 KG.
If this does not help, please create a service request so we could investigate deeper.
