What causes this issue?

The SAP Note implementation test requires from connection &V1& a version
of an object for correction instructions that belongs to a subcomponent.

System Response

The software in the version server &V2& is not yet able to calculate
versions for subcomponents.

How to fix this error?

Create an IT/IBC message for system &V2&. The processing component is
usually DEV-<component-GEN>. For example, the component responsible for
SAP-BASIS is DEV-NWPROD-SYS-ADM, and the component for the core is
DEV-CORE-GEN. Sometimes the responsible component is noted on the logon
screen (if you are logging on without Single Sign-On (SSO)). If you do
not know the responsible component, your quality team can provide
additional information.

Procedure for System Administrators

The administrators of system &V2& need to import SAP Note 1283700 into
system &V2&.
