Hi Experts,

I have Source.Warehouse.SafetyStock, source.Warehouse.ReorderStock

and database2.Warehouse.SafetyStock, database2.Warehouse.PrevSafetyStock,database2.Warehouse.ReorderStock,database2.Warehouse.PrevReOrderStock.

What i need to happen is that database2.Warehouse.SafetyStock to always be equal to source.Warehouse.SafetyStock, database2.Warehouse.ReorderStock to always be equal to source.Warehouse.ReorderStock.

Our ERP system will update the source database and I want the database2.Warehouse.SafetyStock to be updated with this value and the PrevSafetyStock to hold the former source.Warehouse.SafetyStock...

Hopefully this makes sense
