(more than one answers)

A)  EX.
B)  ES.
C)  FX.
D)  HB.
E)  X0.
.

Answers: A, B, C, D

EX = Lot for Lot
ES = Lot for Lot with Split
FX = Fixed Lot Size
HB = Replenish to Maximum

X0 = Planned Externally

Lot-Size Keys are user-definable; just that SAP delivers some standard Lot-Size Keys for immediate usage. Most important is the "Lot-size Procedure" assigned to the Lot-Size Keys which are:

"S" for Static Lot-Sizing Procedure

"EX" Lot for Lot Order Quantity (Demand = Supply after Netting Stocks)

"ES" Lot for Lot with Splitting (with Quota Arrangement)

"FX" Fixed Lot Size ( If the fixed lot size is not sufficient to balance out the material shortage, then several lots are planned for the same date until the material shortage is eliminated.)
"HB" Replenishment to the Maximum Stock level (Max Stock Level - Current Plant Stock - Excising Fixed Receipt Element = Lot Size)

"P" for Periodic Lot-Sizing Procedure

In period lot-sizing procedures, the system groups several requirements within a time interval together to form a lot.
You can define the following periods:

Days

Weeks

Months

Periods of flexible length equal to posting periods

Freely definable periods according to a planning calendar

"O" for Optimum Lot-Sizing Procedure

The aim of optimum lot-sizing procedures, is to group shortages together in such a way that the 

Ordering Costs (Setup and Administrations of Ordering) and Storage Costs (Warehouse and Insurance Costs) are minimized. If you order often, you will have low storage costs but high order costs due to the high number of orders. If you only seldom place orders then you will find that your order costs remain very low, but your storage costs will be very high since warehouse stock must be large enough to cover requirements for a much longer period.
