8 Purge and Archive Data

This chapter contains these topics:

8.1 Purging and Archiving Data

You purge data to remove obsolete and unnecessary data from specific EDI transaction files. Your system is more efficient when you keep these files as small as possible.

You archive data to move data from your system to another type of storage. You can archive both JD Edwards World and translator software records during a purge to one of three places:

  • A library on the iSeries

  • Magnetic tape

  • CD

By archiving data, you can reduce the amount of data that you maintain on your system for historical purposes. You can reload it later to review old data. You must purge and archive System 47 and translator software data separately.

8.2 Purging and Archiving EDI Interface File Data

Navigation

From Electronic Commerce (G47), choose selected transaction

From selected transaction menu, choose EDI Standard document

Purge and archive data that you no longer need to enable your Electronic Commerce system to operate more efficiently. You choose a DREAM writer to purge or archive data from System 47. You specify in the processing options of the chosen DREAM writer to archive the data. When purging or archiving System 47 records, you must first access the JD Edwards World menu for the EDI Standard document transaction whose files you want to purge or archive. Each EDI Standard document transaction menu contains two purge/archive options - one for inbound transactions and one for outbound transactions. You must choose the menu option for purging or archiving inbound or outbound transactions.

When you archive the EDI interface files, the system creates a new physical file in a special purge library and names it JD Edwards World, followed by the current date in system format (without date separators).

For example, if you purge the inbound purchase order file on 01/31/17, the system creates a new physical file in the library JDE013117 with the same name as the inbound file for inbound purchase order detail. If you purge the same file more than once on the same day, the system adds the purged records to the file and does not replace them.

If you purge records, you cannot access them on your computer, but they still take up disk space and they still contain record numbers. You must reorganize the file to permanently remove purged records from the file.

When you reorganize the file, the records that you purged are permanently removed from the file and the system reassigns the record numbers. You can only reorganize files if no one else is using them.

What You Should Know About

Topic Description
Archiving EDI records When you archive System 47 files, the system creates a new physical file in a special purge library and names it JD Edwards World followed by the current date in system format without date separators.

For example, if you purge the inbound price sales catalog file on 01/31/17, the system creates a new physical file in the library JDEO13117 and names it the same as the inbound file for price sales catalog details, F47082. If you purge the same file more than once on the same day, the purged records are added to the file and are not replaced.

Purging unutilized information When you purge records, the purge program also deletes the records from the Unutilized Information file (F4700) if the EDI Standard document program uses this file.

See Section 4.1, "Receiving Inbound Documents" for more information on unutilized information processing.
