Units of Measurement
This section tells you which function modules you can use to process measurement units in your developments.
Overview
Applications often have to convert units of measurement. In multi-lingual systems, and language-dependent measurement units, the measurement unit names must also be displayed correctly in the interface. SAP therefore provides function modules to perform all measurement unit tasks. The information required for each measurement unit is stored in a measurement unit table which the function modules access, to perform conversions.
These include conversion exits, which automatically convert between external and internal format when using domains for input and output fields in screens.
The function modules are buffered, by default, to minimize the number of database accesses required for the conversion. The buffer is filled the first time a module in the function group is called, so this call can take a little longer. A lot of modules in both function groups are used repeatedly, so buffering is worthwhile.
