Regenerating parts of an exchange scheme

You can use the Create ASCII File Fields and Relations (daxch0203m000) session to regenerate parts of an existing exchange scheme. If you do so:

  • The ASCII File Fields group box contains the following check boxes, which, if you click, has the following results:
    • Overwrite ASCII File Formats: If you click Create, LN overwrites any of your exchange scheme’s previously defined ASCII file formats.
    • Create From Definition Files: LN creates your exchanges scheme’s ASCII file’s fields from the definition files of the directory you specify in the Definition Files field of the Exchange Schemes (daxch0501m000) details session.
    • Create Based on Table Definitions: LN creates your exchange scheme’s ASCII files, based on the tables you defined for your exchange scheme in the ASCII File fields of the ASCII Files (daxch0102m000) session.

  • In the Table and Field Relations group box, if you select the:

    • Create Batch check box: In the adjacent fields, you can define a batch for your exchange scheme’s ASCII files. If you do not use the check box, and adjacent fields to define a batch for your exchange scheme’s ASCII files, you must use the Batches (daxch0104m000) session to define a batch manually.
    • Create Import Relations check box: If you click Create, for each of your exchange scheme’s ASCII files, LN creates a table relation in the Table Relation (Import) (daxch0521m000) session, and for each of your exchange scheme’s ASCII file fields, a file field relation in the Field Relations (Import) (daxch0522m000) session. If you do not select this check box, you must manually create your exchange scheme’s import table relations, and import field relations manually in the Table Relations (Import) (daxch0521m000) session, and the Field Relations (Import) (daxch0522m000) session respectively.
    • Create Export Relations check box: If you click Create, for each of your exchange scheme’s ASCII files, LN creates a table relation in the Table Relation (Export) (daxch0531m000) session, and for each of your exchange scheme’s ASCII file fields, a file field relation in the Field Relations (Export) (daxch0532m000) session. If you do not select this check box, you must manually create your exchange scheme’s export table relations, and export field relations manually in the Table Relations (Export) (daxch0531m000) session, and the Field Relations (Export) (daxch0532m000) session respectively.
    • Overwrite Existing Relations check box: If you click Create, LN overwrites any table relations, and field relations previously defined for your exchange scheme.
