No document type found for bus. trans. &1 in company code &2

What causes this issue?

For business transaction &V1& the system could not determine a document
type in company code &V2&.

System Response

The assignment of CO business transactions to document types is done in
the IMG activity
<DS:SIMG.VCFINS_CO_DOCT_M> Variant for Mapping of CO Transactions
to Document Types</>.

How to fix this error?

In case no mapping variant exists, you have to
<DS:SIMG.VCFINS_CO_DOCT_M>create a variant</> first. For business
transaction &V1& you will need to enter a document type there.
If a mapping variant already exists or if you have just created it,
proceed with one of the following options:
In Customizing, assign this mapping variant to the company code &V2&
using this navigation path:
<ZK>Financial Accounting (New) -> Financial Accounting Global Settings
(New) -> Ledgers -> Real-Time Integration of Controlling with Financial
Accounting -> Check and Define Default Values for Postings in
Controlling</>; or

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

<DS:SIMG.VCFINS_CO_DOCT_M>Select the Default Variant checkbox</> in the
mapping variant.
