How To Fix CNV_20100119 - Priority control does not work for merge to account &2 in company code &3

CNV_20100119 - Overview

• Message type: E = Error

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

• Message number: 119

• Message text: Priority control does not work for merge to account &2 in company code &3

What causes this issue?

When checking the priority indicators, the system found that the
priority indicator in the mapping table was set only once for all merges
to target account &V2& (which is correct).
The priority indicator was set for the following mapping:
&V1& -> &V2&
In company code &V3&, the source account &V1& does not exist, while at
least two other accounts are merged to target account &V2&.

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

System Response

As the source account &V1& with prio = X does not exist in company code
&V3&, it is not clear which settings will take priority when the other
accounts in this company code are merged to target account &V2&.

How to fix this error?

Maintain the priority indicator for target account &V2& in company code
&V3& via activity 'Maintain B Segment Merges'. Alternatively check the
settings for the relevant target account &V2& after the conversion.
&ADDITIONAL_HINTS&
Note that the priority indicator must not be set more than <ZH>once</>
for all merges to a given target account. This is also valid for
cross-chart of account merges.
The super priority is mainly useful for tables whose key contains the
chart of accounts, but no other field that needs to be converted in a
chart of accounts conversion, such as account assignment (table T030 and
others).
Note also that even if a <DS:TX.CNV_20100_TX_SUPERPRIO>super priority</>
was defined at chart of accounts level it is still not clear which
settings (from which account or cost element) will prevail during a
merge to a given target if <ZH>more than one</> account or cost element
from the <ZH>same</> chart of accounts is merged into this target.
