How To Fix CNV_20100308 - &1 &2 with overlapping intervals &3

SAP Error Message - Details

• Message type: E = Error

• Message class: CNV_20100 - Messageclass for chart of account conversion

• Message number: 308

• Message text: &1 &2 with overlapping intervals &3

What causes this issue?

According to the mapping, the financial statement keys &V1& &V2& get the
following overlapping intervals: &V3&.
However this is not allowed for financial statement versions.
The overlap occurs as a result of the conversion of interval &V4&.

System Response

With the current settings, the second of the two overlapping intervals
will be removed from the financial statement version.

How to fix this error?

You have the following options:
Adjust the mapping of G/L accounts and interval limits,so that no
interval overlaps occur in the financial statement versions.
Resolve the intervals of the affected financial statement versions into
to single values.
Keep the mapping unchanged. In this case, the account assignments that
lead to interval overlaps are removed from the financial statement
version. Note that this may result in financial statement keys without
account assignments.
The last option is only recommended if only a few overlaps occur,
because otherwise the effort to adjust the financial statement versions
later is considerable.
