Project Task Level transaction Control Limits

Summary:

 We have a requirement to use Transaction control to limit the number of tasks to be visible on the Time Entry and Expense Entry. We only want to have a time entry and expense entry user to see the tasks assigned to a specific resource in Project-level transaction control.

Below are the questions related to the same functionality :

1. Is there any limit to the transaction control in terms of the number of line items, which can be created for this functionality to use?

2. Is there any limit to the transaction control in terms of the performance of the system in other areas e.g. Billing, revenue, expense entry ?
