Its a known issue with Restriction Rule 99. This occurs when there are lots of access groups belong to the selected access context code. System gives the time out error while creating the hierarchy among these access groups to show it on the screen.

Calculation rule 99 which is freestyle definition of restrictions is only a fall back functionality, having business roles with fixed restrictions will defeat complete purpose of business roles, which were supposed to be more dynamic, calculate / determine restrictions based on user's properties the sales unit to which they belong to.

So, provide authorization (by using other restriction rule, other than 99) to user based on business role using existing restriction calculation rule.

In case existing restriction calculation rules are not cater to the needs of business use case, so we kindly request you to post this query in the forum SAP Customer Influence Site (https://influence.sap.com/SAPCloudforCustomer)  to the access context owners to provide required logically determinable calculation rule which can be implemented for them.
