Close Collector/Queue 
You use this function to close collectors and queues automatically based on the closing criteria defined in a clearing agreement and to close collectors and queues manually.
The closing criteria for collectors are based on any of the following attributes:
Maximum amount
Defined time with or without a minimum amount and a minimum number of items
Maximum number of payment items
End-of-day processing
Payment items in a queue or collector with the status Closed are locked for processing and no more payment items can be assigned.
The reasons you can specify for closing collectors are:
Maximum total reached
Maximum item number reached
Final time reached
Closed manually
Time and minimum total reached
Time and minimum item number reached
Time, minimum total, and minimum item number reached
Closed during end-of-day processing
No posting-relevant items
Maximum total reached and maximum item number reached
Integration
The system assigns payment items to a collector category or a queue category based on the collection criteria defined in clearing agreements. If at least one of the attributes in a payment item does not match the criteria defined for the open categories, the system generates a new collector category or queue category with a new collector number. It then assigns the payment item to this category.
Each collector category and queue category is given a collector number based on a number range that you define in Customizing.
The system assigns the payment items to new or existing sequences depending on the closing criteria defined for the category in the clearing agreement. For more information, see Clearing Agreement.
Prerequisites
You have defined the closing criteria: On the SAP Easy Access screen, choose 
Payment Engine 
Master Data Routing Control Manage Routes and Clearing
Agreements 
(transaction /PE1/RN).
Features
You can specify the following closing conditions for a particular queue category or collector category:
Time-based closing criteria
You can specify that collectors and queues close at different times and at different time intervals. You can also specify the minimum closing criteria for a scheduled closing time.
Non-time-based closing criteria
You can specify that collectors and queues close when the number of payment items reaches a maximum item limit or a minimum amount of x currency units.
You can specify multiple closing criteria for a queue or collector. If one closing condition is met, the system closes the queue or collector and you can no longer assign payment items to the queue or collector.
Note
When you close queues or collectors manually, the system ignores the closing criteria defined in the clearing agreement.
