Objects of company code &2 are not permitted

What causes this issue?

The affected company codes are derived from the controlling area
specified in the reorganization plan. Fiscal year variants may be
assigned to the combinations of company code and ledger. Any such fiscal
year variants must agree with the fiscal year variant of the controlling
area specified in the reorganization plan.
The fiscal year variant of the controlling area is . However, fiscal
year variant &1 is assigned to the combination of company code and
ledger .
You can allow a balance sheet transfer in ledger with the fiscal year
variant . Note, however, that the balance sheet transfer documents are
posted using the reorganization date as the posting date.
Example
In the reorganization plan, you specify April 1 of the current fiscal
year as the reorganization date. Since the leading ledger has fiscal
year variant K4, the posting periods are identical to the months of the
calendar year. Fiscal year variant XX, which always starts on the 14th
day of each calendar month, is assigned to non-leading ledger N1;
consequently, on April 1, period 3 is the current period.
The reassignment and transfer of the material balances take place on
April 19. The transfer documents are posted with the document date April
1 (= reorganization date). In this way, balances that resulted from
transactions (such as goods receipt) between April 14 and April 19 are
also posted in ledger N1 in period 3. Transactions that occurred after
April 14 nevertheless belong in ledger N1 in period 4, not period 3.
