  3. Save your new scheme, close the details session, and return to the Exchange Schemes (daxch0501m000) overview session.
  4. In the Exchange Schemes (daxch0501m000) overview session, select your new exchange scheme, and on the Specific menu, click ASCII Files to start the ASCII Files (daxch0102m000) session.
  5. Click the New icon to define a new ASCII File for your exchange scheme. In the ASCII File field, you must enter the name of the table you want to export. LN fills the Description field with the description of the table. Define all of your exchange scheme’s required files.

  • This procedure does not make use of the multiline text feature. To use multiline texts, you must change the Field Type of the involved fields in the ASCII File Fields (daxch0503m000) session, and on the Specific menu, click Recalculate Start Positions to recalculate the start positions of the file fields.
  • If your exchange scheme is based on audit, you must activate the audit trail for the involved tables through the Generate Audit Configuration (daxch1201m000) session. You can start this session from the Specific menu in the Exchange Schemes (daxch0501m000) session. Subsequently, you must convert the new audit settings to runtime through the Create Runtime Audit Definitions (ttaud3200s000) session.
  • Before you can run the new exchange scheme, you must generate the export and/or import scripts through the Create Export Programs (daxch0228m000) session and/or the Create Import Programs (daxch0227m000) session.
