ISO codes for Units of Measure

Hi Smith,
Go through the below explanation, which would be helpful for you.
Check units of measurement
In applications you often have to make calculations with quantities and physical units. Units of measurement are needed for their screen display and for internal conversions (such as kilogram <-> gram, but also centimeter <-> inch). The international system of units (SI) is used for this.
The international system of units is based on seven basic units of measurement. All other units are derived from these basic units. Units of measurement that measure the same quantity (and can therefore be converted into each other) are included in a dimension.
Units of measurement are held centrally in the SAP System for all applications. The conversion factors are stored in the system with a unique internal key. The external display specifications are maintained for each unit of measurement language-dependently. A business key (3 characters) and a technical key (6 characters) should be maintained for each language.
Standard settings
In the standard delivery system, units of measurement are defined according to the international system of units (SI).
For a new installation, units of measurement are delivered in all clients. For upgrades, new units of measuremente are delivered only in Client 000. They then still have to be transported to the production clients.
Recommendation
If you intend to perform cross-company data exchange, note that units of measurement with company-specific characteristics may have an adverse effect.
Activities
Check that the dimensions delivered and the associated units of measurements are complete.
If you are using EDI, you should also check the ISO codes.
Dimensions
1. Call the maintenance transaction by double-clicking with the mouse on the Execute symbol.
2. On the initial screen of the maintenance transaction, call the function Dimensions
To get a definition of a dimension, place the cursor on the dimension and choose the function Details.
3. If required, create new dimensions with the function New entries.
Units of measurement
1. Call the maintenance transaction by double-clicking with the mouse on "Execute", or press F3 to leave dimension maintenance and return to the initial screen of the maintenance transaction.
2. Select - from F4 Help for the field next to the Units of Measurement function - the individiual dimensions, and choose the Units of Measurement function.
To get a definition of a unit of measurement, position the cursor on the unit of measurement and choose the function Details.
3. If required, define new units of measurement according to the international system of units (SI) with the menu function Unit of meaurement -> Create.
Here you have to make make specifications for:
Display (including a descriptive Units of measurement text)
Conversion (not applicable to units of measurement without dimensions)
Data exchange (EDI) (optional)
Application parameters
ISO codes
1. Call the maintenance transaction by double-clicking with the mouse on "Execute", or press F3 to leave maintenance of units of measurement or dimensions and return to the initial screen of the transaction.
2. Choose the function ISO codes.
3. If required, maintain new ISO codes with the function New entries.
Hope this helps.
Thanks,
