Determination of Units of Measure for Rounding or Ordering
The system checks the following parameters before performing rounding:
Percentage rate for discarding requirement of a product (if net requirement is < 1)
Article-specific minimum order quantity
Permitted units of measure for rounding
The following settings have an effect on the units of measure that the system selects for rounding or ordering:
Order unit
It is assigned to the transportation lane for products (connection between location product and source location). SAP F&R copies this assignment through the interface. If no unit of measure is defined, the system uses the base unit of measure of the product as the order unit. The order unit is always one of the units of measure that are permitted for rounding and ordering even if it is excluded by a unit of measure group.
Variable order unit
This setting determines whether SAP F&R can only round a product up to the order unit, or whether any allowed unit of measure can be used. The following options exist:
Variable unit of measure for rounding and ordering
The system can round up to any defined unit of measure. The product is ordered in the rounded unit of measure.
Variable unit of measure for rounding but not for ordering
The system can round to any defined unit of measure, but orders the product in the order unit.
Variable order unit is permitted for neither rounding nor ordering
Rounding and ordering are performed in the order unit.
UoM groups defined for the source and destination locations
How does the system determine the unit of measure for rounding?
You assign the parameters to determine potential rounding units in the master data for the transportation lane for products:
If you have not defined a rounding profile, no rounding is performed. The system uses the base unit of measure for the quantity.
If you have defined a rounding profile but no variable unit of measure for rounding, the system rounds the quantity required to the order unit.
If you have assigned a rounding profile and defined a variable unit of measure for rounding, the system calculates the permitted order units based on the unit of measure groups for the source and destination locations. The following rounding units are permitted:
The order unit
The intersection of units of measure as defined in the following places:
In the product master data
In the rounding profile
In the unit of measure groups
How does the system determine the final order unit?
SAP F&R determines the possible order units for a transportation lane for products as follows:
If a variable unit of measure is not permitted for the purchase order:
The order unit defined in the master data for the transportation lane for products is the only unit of measure that is permitted. The system converts the rounded amount (or, if no rounding profile is assigned, the net requirement) to the order unit. If the result is not an integer, SAP F&R calculates the decimal places, trimming the result to the allowed number of decimal places in the process.
If a variable unit of measure is permitted for the order:
The permitted order units correspond to the permitted rounding units.
