How To Fix CNV_10020770 - &1 &2: &3 does not allow initial target determination values

CNV_10020770 - Overview

• Message type: E = Error

• Message class: CNV_10020 - Message class for package 10020

• Message number: 770

• Message text: &1 &2: &3 does not allow initial target determination values

What causes this issue?

The determination result of &V3& is compared with a value list &V4& that
contains the value space. By default, determination paths treat an
initial target determination value as a missing information. The result
is a determination failure.

System Response

A comparison with space won't be performed.

How to fix this error?

If you want to treat the initial value as a value, go to the path
definition of &V3& using transaction CNV_10020_OBJECTS. On the tab strip
"Determination" set the indicator "Allow initial TDetValues"
accordingly. You can do this only for elementary relationships and
converter paths. For single and multiple paths it has to be done for all
of their sub paths.
