However, this set type is not known to the API interface.

System Response

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

How to fix this error?

This error has two possible causes:
The name of the set type was transferred incorrectly (the name must
always be specified in uppercase).
The set type is not contained in the API interface. If the set type is
to be maintained using the API, it must first be transported and
appended to the API structure in the same step. You can do this in the
<DS:TRAS.COMM_ATTRSET>Maintain Set Types and Attributes</> transaction
by choosing <LS>Set Types/Attributes</> -> <LS>Transport</> ->
<LS>Include in Request</>. Set the <LS>Create API Append</> indicator.
The set type must be allowed for product type &V2&.
