Algorithms 

Number interval
Here, you specify the intervals within which the values of your document numbers and/or reference document numbers can lie. The program ignores values not contained within these intervals. They cannot be used as information to clear open items.

The reference number entered in the account statement by your customer or house bank must be in the same format and of the same length as the number in the SAP system.

You send your customer a bank transfer form with the reference document number 000101. However, the customer only forwards the last three digits of this number on to your house bank. The number (101) then appears on the electronic bank statement too. The system is unable to locate this number. For this reason, it is essential that customers and house banks do not omit leading zeroes from such forms when processing electronic bank statements.

Bundling
You can use this field to determine whether and if so how bank statement items should be grouped into bundles. If you have the program post the bank statements immediately (call transaction), you can select the items of a bank statement in the postprocessing function by bundle. If you use batch input sessions, you can generate a separate session for each bundle.

Under bundle type 1 (bundle per accounting clerk), the system enters the accounting clerk ID from the customer master record into the field. If the customer cannot be uniquely identified from the bank details, the field remains blank.

Under bundle type 2, the system creates a bundle per n items, enabling up to 99 bundles to be created.  If you enter n = 100, the first 100 line items are contained in bundle 1, the next 100 items in bundle 2 and so on. If you enter n = 1, line items 1 to 99 are entered in bundles 1 to 99. The 100th line item is then entered starting once again from bundle 1.
