Message type: E = Error
Message class:  CNV_20100 - Messageclass for chart of account conversion 
Message number: 036
Message text: Company code &1 for chart of accounts &2 was not indicated
If you omit at least one company code that uses a chart of accounts that
you want to convert, the conversion will be carried out dependent on
organizational units to make sure that the accounts of the company code
that was not indicated (and consequently does not participate) are not
converted.
The system found that company code &V1&, which also uses chart of
accounts &V2&, was not included in the mapping.
Check if you really want it to be that way, or if the missing company
code &V1& was forgotten by accident. If necessary, include the missing
company code in the mapping table.
&ADDITIONAL_HINTS&
If the chart of accounts &V2& is not renamed and no accounts are
changed, then this message can be ignored. In this case the
corresponding mapping entry (&V2& -> &V2&) will be identified as
delimitation scenario in activity 'Determine Scenario'.
For the conversion of a group chart of accounts all company codes of the
operative charts of accounts (which indirectly have the chart of
accounts as group chart of accounts) must participate in the conversion.
For the conversion of a group chart of accounts all company codes of the
operative charts of accounts which have the chart of accounts as
country-specific chart of accounts  must participate in the conversion.
