This field is about of the balance Amount that sent by the switch.

Answer 1

The values of the types of accounts and amount types and the conditions in which they are allowed vary by each instance and variation of ISO-8583 but the standard format is the following:
The data element breakdown, occurring up to six times for a total length up to a total length of 120.
Position Data 1-2
Account Type (n 2) 3-4 (Must match DE003 format)
Amount Type (An 2) 5-7 (See Table Below for a sample of SOME of the values)
Currency Code (n 3) 8-20 (ISO-3166-1 Numeric, just like DE049-DE051)
Amount (x + n 12)
The amount must not be greater than 999999999.
"X" must be 0, C, or D. C or 0 = Credit amount and D = Debit Amount
Some of Amount Types others really vary by specification and though these are all numeric the Healthcare transactions are AlphaNumeric values in the VISA specification for example. Note that most of these are actually not commonly used in PIN or Debit transactions except 01, 02, 40-43, 57, 58, and 91.
