Transaction sets are organized under categories

The name of the category is the same as the name of the Funct'lGroup type that contains that particular transaction set. For example, the #102 transaction set is a subtype of the #102 category, just as the Funct'lGroup category that contains the #102 transaction set is called #102.

The #844 transaction set is contained in a functional group that can have both #844 and #849 transactions. The functional group type name is CF, so the actual transaction set #844 is found under the category named CF.

If there is only one transaction set under a category, the transaction set type name is simply Transaction. If there is more than one transaction set under a category, the type Transaction is partitioned and the separate transactions are subtypes of it. For example, the actual #844 transaction set has the name #844 and is a subtype of Transaction.

The ST Segment is the first component of each transaction, and is used as an identifier, the value of the TSIDCd Element in the ST Segment tells what transaction it is, in this case, #844, or #849.

If a transaction set cannot be found by its transaction set number, use the Find command. For example, if you did not know that the #844 transaction set type was under the CF category, you might find it by choosing Find from the Edit menu, and entering #844 in the Find What field.
