Cannot derive attribute information from column &1 in "&2"

What causes this issue?

At least one of the components you want to upload contains a reference
to an invalid data object. A data object is a part of the data model as
maintained in transaction MDCMODEL, and only names of objects that are
marked as "process relevant" are considered valid during imports of
files.

System Response

For the import to work, it is essential that every column in your file
corresponds to a valid data object and a valid field of that data
object. If one of them is invalid (or empty), the import will fail and
raise this or a similar error message.

How to fix this error?

Make sure all names of all components of your file (i.e. workbook sheets
when your file is a Microsoft Excel document, or CSV file names when
your file is either a CSV file or a CSV file package) start with a valid
data object name. Run transactions MDCMODEL or MDCIN to compare the
names.
If the table name is empty or the column mentioned in this message seems
to be empty when you check your file, there might be invisible
characters in your document. For example, this can occur when cells of a
workbook sheet are not entirely deleted. In this case, select the
complete column in your document by clicking its header<(>,<)>
right-click the selected column(s), and choose "Delete" in the context
menu.

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