Multiple MRPs of same article which having same UPC

Hi,

There is one requirement i hv come across -

A same article is been procured from same vendor on different prices on different periods. Based on different purchase prices, system calculates different MRPs of same article which is having one UPC only. Now business wants to flow all MRPs to the POS system and POS system should have capability to pop up all MRPs on its screen so cashier can opt the right MRP and sell the item from POS.

Now my question is how will system maintain different MRPs of same article which has a common UPCs. If we can maintain multiple MRPs for same article then how will send all MRPs details to POS system.

Please do let me know if you need any more details.

Thanks,

Ashish Kumar
