SAP Note 14116 - Runtime error CONVERT NO_NUMBER in UNIT_CONVERSION

Symptom:

Runtime error CONVERT_NO_NUMBER in function module
UNIT_CONVERSION: a CHAR field cannot be converted to FLTP, because exponent "E-+55" or something similar.

Cause and prerequisites

UNIT_CONVERSION is unable to process 3 digit exponents.

Solution
- Usually, no numbers with 3 digit exponents occur in the
application.
Apply note 10738 first.
- Should the error occur again, use a function module of group
SCV0 (UNIT_CONVERSION_SIMPLE, CONVERSION_FACTOR_GET) in the
requesting program instead of UNIT_CONVERSION. If you want to
convert depending on the material master, use function module
MATERIAL_UNIT_CONVERSION .

In order to find the name of the requesting program, read the dump
(list of active calls/events).
The change should be carried out by the developer responsible
for the application.
