We recommend adjusting the programme end date from the User's profile. In the programme details tab, update the End date, uncheck 'Update ILR with changes', and save (as shown below). Subsequently, regenerate a new Apprenticeship agreement.
This process will ensure that no alterations are made to the ILR, while updating the end date of the programme to the desired date, which will then reflect in the regenerated Apprenticeship agreement.
