In OMI4 ie. MRP lot size procedure i see several MRP lot sizes i.e. EX, WB etc....
But only major difference i find is in terms of scheduling i.e.
Blank (Requirement date = delivery date), 1 (period start = delivery date), & so on i.e. 2, 3, 4
Can anyone tell how it works?????? What is its significance
Example would be very good for me
