How To Fix CNV_20100201 - Merge at A/B level: No priority control for merge to account &1

CNV_20100201 - Overview

• Message type: E = Error

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

• Message number: 201

• Message text: Merge at A/B level: No priority control for merge to account &1

What causes this issue?

The system found that two or more old G/L accounts are mapped to target
&V1&, but the priority indicator is set for none of these accounts.
If the priority indicator is not set, it is not clear which settings
will take priority when the accounts are merged to &V1&.
Besides, the check showed that the merge will be carried out at
<DS:TX.CNV_20100_TX_ASEGMENT>A level</> as well as at
<DS:TX.CNV_20100_TX_BSEGMENT>B level</>.
At B level, the following accounts in company code &V4& will be merged:
&V2& -> &V1&
&V3& -> &V1&

How to fix this error?

Set the priority indicator for <ZH>one</> of the entries with target
account &V1&.
&NOTE&
It is possible to do the conversion without setting the priority
indicator. In this case, however, you should check the A and B segment
settings for the account &V1& after the conversion.

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

&ADDITIONAL_HINTS&
This message is also displayed if the merge is implicit. In this case,
the log will contain another message for target &V1& that describes the
recommended next steps.
The priority indicator must not be set more than once for all merges to
a given target. This is also valid for cross-chart of accounts merges.
The super priority is mainly useful for merging records in tables that
have only a chart of accounts field, but no account/cost element field,
as well as in tables for which the priority indicator has not been set
at G/L account/cost element level so that it is not clear which of the
records is meant to take priority.
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 take priority during
a merge to a given target if <ZH> more than one</> account (cost
element) fromthe <ZH>same</> chart of accounts is merged into this
target.
