Record and Field Selection

Record selection and field selection are features that allow you to transfer only the records and fields you specify. This feature is part of the PWRFROM3XB command. Record selection and field selection are not mutually exclusive functions of ETU, although it's not necessary to use them together.

NOTE: Record and field selection can be used only with externally-defined host physical files.

About Creating Auxiliary Storage Pools

The Record and Field Selection feature within the PWRFROM3XB command will not work properly if you define one or more additional Auxiliary Storage Pools on the AS/400. This is because ETU creates temporary work files in the library QTEMP, which is always located in Auxiliary Storage Pool #1 (which comes with OS/400). If you create an additional Auxiliary Storage Pool, ETU cannot create the work files associated with the data file that is stored in any newly created Auxiliary Storage Pools.

If you do create a new Auxiliary Storage Pool, you can simulate record and field selection in a file transfer operation by creating a logical file or and open query file and transferring those files.

Transferring Selected Fields

When you transfer a physical file from the host to a micro with the PWRFROM3XB command, you have the choice of transferring all the fields in the file, or, using field selection, transferring only the fields you select. You can also specify the order in which the data will reside in the micro file.

For each field you select to transfer, supply information to the following parameters, found under the heading FLDSEL (field selection) on the PWRFROM3XB prompt screen. The parameters are:
