Rounding Profiles
SAP F&R requires logistical rounding profiles for requirement quantity optimization to round quantities to multiples of a unit of measure, for example, or to switch between units of measure.
Integration

You assign the rounding profile in the transportation lanes for products. On the
SAP Easy Access
screen, you choose . 
You can import rounding profiles. For more information, see Inbound Interface for Rounding Profiles.
Prerequisites
To perform rounding, you must have defined the rounding parameters
in the profile for requirement quantity optimization. Rounding must be active in the basic settings of the profile. The tables below illustrate how the Rounding Type
and Rounding Mode
parameters affect rounding behavior:
Rounding Type 
Rounding Behavior 

Total requirement 
The threshold values are calculated using the following formula: 1   (rounded quantity – requirement quantity) / rounded quantity  [The quantity calculated within the absolute value brackets (" ... ") is always used as a positive value, for example,  10  = 10.] 
Individual logistical unit of measure 
Depends on the percentage missing to the nearest multiple of a unit 
Rounding Mode 
Rounding Behavior 

Rounding up and down to the largest unit of measure is preferred 
The system uses the largest possible unit of measure as the order unit. 
Always prioritize rounding up over rounding down 
The system always tries to round up to a unit of measure. If this is not possible the system rounds down. 
For more information, see Profile for Requirement Quantity Optimization.
Features

You can define rounding rules that specify the percentage from which the system rounds for a given unit of measure. You can specify threshold values for rounding quantities up and down. Based on these rules, requirement quantity optimization determines which of the permitted units of measure is most suited as the requirement quantity.

You can use zero rounding. It determines what happens when the rounding result is zero and no purchase order can therefore be created. You can choose which of the following rules you want the system to use:

Do not round to zero

Round every possible rounding unit down to zero

Only round the unit of measure with the smallest base unit down to zero

Activities
In maintain rounding profiles, go to the SAP Easy Access
screen and choose .
Example
Pallets and boxes are possible rounding units. Rounding shows that the order quantity is so small that it will not fill a whole pallet. The system rounds down to zero, which means nothing is ordered. You have the following options for zero rounding:

If you select the rounding mode in which SAP F&R rounds every possible rounding unit down to zero, no purchase order is created because the system rounds the rounding unit pallet down to zero.

If you select the option in which SAP F&R only rounds the unit of measure with the smallest base unit of measure down to zero, the system cannot round down to zero, as the unit of measure pallet is not the smallest possible unit. The system checks whether a box can be ordered. If so, it orders the box; if the quantity is too small for a box as well, nothing is ordered, because no smaller rounding unit is defined.

If you choose the option that SAP F&R cannot round down to zero, the system orders a box.
