Import requirements from a CSV file

 I was trying to import a csv requirements file into DNG to update a module but I am getting multiple errors:
- If i try to import directly my file into DNG, I get the next error


ID CRRRW7571E This error can occur for several reasons. For example, you might not have permission to import an artifact type that is in the file, a row or resource might be locked by someone else, or the file might not meet the requirements to be imported. For instance, one or more rows might contain a type that is not in the type system. It's also possible that an incoming link cannot be created in another component because it is a baseline or requires a change set. Update the file, the type system, your user permissions, or all of these items. Also, confirm that the components allow the creation of outgoing links. If incoming links are being created in other components that require change sets, create a change set in the other component and add that change set to a personal stream along with the current stream or change set.

- If I generate a CSV from an exported view and then copy the data into that CSV and import it back, I get the next error:
