How To Fix CNV_NCE_BAS042 - &1 Range &2 &3: unable to define target interval

SAP Error Message - Details

• Message type: E = Error

• Message class: CNV_NCE_BAS - Number conversion engine: messages

• Message number: 042

• Message text: &1 Range &2 &3: unable to define target interval

What causes this issue?

The program has determined that a new number range interval is required
for a successful generation of the mapping proposals. Due to some
reasons it is impossible to create a new interval automatically.

System Response

The program generates mapping proposals on basis of subobject mappings.
It maps all intervals of the source subobject to the same intervals of
the target subobject. If target subobject does not have an interval with
the same number or year (for year-dependent objects) the program tries
to create it with the same number limits as the source interval.
In some cases automatical creation of new number range intervals is
impossible:
new number range interval will overlap already existing one;
there are several source intervals with different number limits that
should be mapped to the same target interval.

How to fix this error?

Define corresponding number range intervals for a target subobject with
help of standard SAP transaction SNUM.
