Cost center category and ID definition

Meaningful cost distribution and charge-out requires a systematic means of customer/transaction identification.

Associating transactions with specific customers in the IMS environment is accomplished with a unique transaction identifier. The 26-byte identifier is composed of a customer ID and a transaction code. The 18-byte customer ID is defined by the user. The 8-byte transaction code identifies the unit of work.

The IRUF maintains the customer ID in the terminal and transaction accounting records. The contents of the customer ID field are set in the customer exit routine (PRSCEXIT) in the Log Edit (IMFLEDIT) program. The default, set by the distributed version of PRSCEXIT, is to use the name of the input logical terminal of the transaction as the customer ID. However, PRSCEXIT can be modified to set the customer ID field as required.

Note

To avoid loss of data granularity during summarization, the LTERM should be maintained (either physically or logically) as part of the customer ID field. For more information, see the information about setting up customer IDs inMainView for IMS and MainView for DBCTL Customization.

The customer ID and transaction code are used by the Transaction Accountant to accumulate processing charges. All charges are calculated at the transaction level and then accumulated for each customer category.
