You may experience the error "Mandatory: Client group" when creating or editing a client in practice management. When you try to fill in the mandatory field you receive the error "The data you are requesting cannot be found or you do not have sufficient rights to perform this operation. Please contact your administrator to have the correct rights assigned.".
This issue only occurs in Practice management when you have the CRM link between Practice management and Exact Online Jaarrekening/Fiscaal. As a workaround you can disable the following setting to be able to create and/or edit clients: Company settings > Tab Accountant > Exact Online Jaarrekening/Fiscaal > Disable 'Mandatory CRM fields'.
We are investigating this issue, and we will update this page as soon as more information becomes available. Our apologies for the inconvenience.
