Pricing error: Field overflow

What causes this issue?

A field overflow occurred when condition conversion factors were being
determined.

How to fix this error?

Proceed as follows:
RESET N1
Check the conditions and determine where the field overflow occurred.
Field overflows can for example occur during quantity conversion (for
example, if the unit of measure in material master is gram, but the
condition is specified in EUR per tonne), during currency conversion
(for example, if the document currency is USD, but the condition is
specified in EUR), or when quantity multiplied by price results in a
very large amount.
Change the factors involved in the calculation in the master records or
in the document so that field overflow can no longer occur.
