Document split not supported for country &1.

What causes this issue?

The posting includes a company code that is assigned to the country
<(>&<)>V1<(>&<)>. However, the document split is not supported for this
country.

System Response

The document split cannot be carried out for all countries. For some
countries, legal requirements are in place that do not permit an
incoming or outgoing invoice to be split, or country-specific reports
exist that do not support this kind of split posting.

How to fix this error?

First check whether a note is already linked in the collective note
2078335 for the country <(>&<)>V1<(>&<)>. If that is not the case, check
whether the country is listed in SAP Note 2144221. If the country is
included in SAP Note 2144221, the document split cannot be carried out
for this country.
However, if the country <(>&<)>V1<(>&<)> is not included in either of
the two notes, create a customer message on component FI-AP-AP-J or
FI-AR-AR-J and refer to the SAP Note 2144221. We can then use this
message to check whether the document split can be approved for the
required country.
