Is it possible to change the Inventory Valuation Unit of Measure or Logistics UoM for a Material Item? You have changed the Base Unit of Measure but the Inventory Valuation Unit of Measure (UoM) and Logistics UoM remains unchanged.
In Valuation tab of a Material, if you activate the Companies/Business Residence, then it is not possible to change the Inventory Valuation UoM after that. All the Business Residence used in the Valuation tab will take the same UoM as set for the first time.
Similarly, In Logistics, Planning and Availability Confirmation tabs of Materials, it is not possible to change UoM once it is activated.
NOTE: Other than Sales and Purchsing, all other tabs are dependent on each other. Ex: if you have activated Business Residence in Logistics, then you cannot edit the UoM in other tabs ex: Valuation.
This is general system behavior.
To overcome this situation, you can maintain the quantity conversion in the Material for the old UoM to the new UoM.
1. Go to Product data work center.
2. Select Materials view.
3. Edit and go to General tab of that Material,
4. Where, you can maintain the quantity conversion between the old Base UoM and New UoM or vice versa.
