Have few doubts in these routines.
CONVERSION_EXIT_CUNIT_INPUT "Conversion exit for commercial (3-char) measurement unit INPUT
CONVERSION_EXIT_CUNIT_OUTPUT "Conversion exit for commercial (3-char) measurement unit OUTPUT
Dont understand the functionality of these rules, in the sense i just understood that these rules are used for conversion from one Input form to Output form and viceversa.
Can anyone explain if there is any other underlying functionality involved in these Function Modules.
