 Hi,

In Material workbench can possible to seprate lot stock price wise ? see example below

Same item

X lot stock is 100 price is Rs. 5

Y lot stock is  200 price is Rs. 7

In our industries many times item price change frequently so we need to check price wise stock in system .At present we maintain same item stock manually. Pl. suggest any best solution how to maintain stock price wise in system.
