Error reading the data of InfoProvider &1

What causes this issue?

Errors have occurred while reading a VirtualProvider outside the BW
system. Check whether the previous error messages contain any in
formation about the possible cause of this error.
It is possible that the error message cannot be displayed because the
error message class does not exist in the BW system. If this is the
case, only the name of the error class and the message number are
displayed. Read the error message text in the specified error class in
the VirtualProvider source system.

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?

Since the error is not necessarily in the BW system, there is no
specific procedure for resolving it. With VirtualProviders, problems
often occur with the connection to the remote system. These can cause
the system to terminate. If the code for the VirtualProvider is not from
SAP, contact the person responsible in order to resolve the issue.
If an SQL error is listed in the previous message, see the procedure for
<DS:NA.DBMAN257>SQL errors</>.
