No new article number supplied for '{0}'

 
 
Error:
No new article number supplied for '{0}'.
 
Explanation:
When renumbering article numbers, a new number must be specified for each old article number.
In the import file there are lines where a new number has been forgotten, or there are still lines in the import file that should not be changed..
 
Solution:
Find the lines in which no new article number has been entered. Enter a new number or remove the line from the import file.
