How to Avoid Multiple Overrides in Pending State
Description
When creating overrides for a filtera set of specified criteria that are applied to data in order to identify the subset of data for a subsequent operation, such as continued processing. , you can specify one or more time periods for the override value. The overrides for each of the one or more time periods are grouped into a transaction that is pending until you submit it. Overrides can be pending for only one filter. If a user tries to create an override for a new filter before submitting overrides for another filter, the pending transaction must be submitted first before the new one can be saved.
However, when a project is shared, it is possible for users to work independently in the Overrides tab and create multiple overrides for different filters in pending state. This can cause conflict resolution problems that cannot be easily resolved.
Solution
If pending overrides for different filters are created simultaneously, you must delete at least one of them to correct the problem.
To prevent this problem,
check 
in the project banner before adding overrides to
make sure other users are not editing the project. Click 
to determine whether any other overrides have been
created or submitted before submitting any new overrides.
