How To Fix CNV_20100612 - 'Valid until' date for &1 differs from &2 in company code &3

CNV_20100612 - Overview

• Message type: E = Error

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

• Message number: 612

• Message text: 'Valid until' date for &1 differs from &2 in company code &3

What causes this issue?

According to the mapping table, you want to merge cost elements &V1& and
&V2& in controlling area &V3& into the new cost element &V4&.
As the <zk>End of validity date (DATBI) </> is different for the two
cost elements, the validity periods may overlap.
Depending on the entries made in the mapping table (priority indicator),
the start and end dates for cost elements may change, and the validity
periods of the remaining validity intervals for a cost element may
overlap.
These inconsistencies are removed in phase Postprocessing Programs
DURING System Lock, activity <ZK>Adapt Validity Date for Cost Element
Groups</> by processing all remaining validity intervals for a cost
element in accordance with the following rule:
All validity intervals for a cost element are considered and adapted
starting with the oldest interval (oldest valid-from date) and
proceeding into the future.
The valid-from date (CSKB-DATAB) that is furthest in the past <ZH>after
</> the conversion is set to the valid-from date that was furthest in
the past <ZH>before</> the conversion.
If the valid-from date of the next interval is lower than the valid-to
date of the interval that is currently processed, the valid-from date of
the next interval is set to the valid-to date of the current interval
(plus one day).
The valid-to date that is farthest in the future <ZH>after</> the
conversion (CSKB-DATBI) is set to the valid-to date that was furthest in
the future <ZH>before</> the conversion.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Note that checks/changes in the area of cost element validity will be
required after the conversion.
Find ouf if the logic of the changes (as described above) suits your
needs, and change the validity periods manually after the conversion if
required.
&ADDITIONAL_HINTS&
This message is just a warning that additional work may be required
after the conversion.
The log for the program for adapting the validity dates for cost
elements contains detailed comments on what changes were made in which
places.
