Modifying a partner after recieving a borrowing request should be possible
In the SNLP workflow the partner changes from the own partner code to the partner who ships the request automatically. Therefore most of the requests have the correct partner when the item arrives at the library.
So most of the time there is no need to modify a partner and the staff's attention to this attribute is not as high as it is to other attributes of the request. If we observe this AFTER receiving the item, there is no possibility to do so.
Because we don't know to which partner we have to send back the item after it has been returned by the patron, we now have to missapply other fields of the request to store this information.
Perhaps not all libraries want to allow their staff to do so, so we suggest a new parameter which can be switched off, if it is not needed.
