Transaction misses debtor's name

There is a transaction where alexia does not display the name of the debtor. This is most likely caused by the person having logged into alexia before becoming a member of an association utilising alexia. Therefore no name was linked to the student number at first, but also failed to link after the student had become a member at Inter-Actief.

Start by reproducing a transaction for a student who logged in before joining Inter-Actief, then trace how the transaction retrieves the debtor name from the student number. The issue is done when the debtor's name appears after the student becomes a member, including for existing transactions.
