5.11.4 Select the Maintenance Access Path
Once the physical file that is maintained has been selected, a screen similar to the following example will be displayed:
|
DC@P201101 Select Maintenance File to use
File : DEMNAME DC@DEMOLIB Demo Names File
From list choose view of this file that is to be used for maintenance
Sel File Description / Access key information _ DEMNAME Customer master file Access by : DEMNAC Name code
_ DEMNAMEN View of customer master by customer name Access by : DEMNAM Name
_ DEMNAMEP View of customer master by postcode Access by : DEMPCD Postcode
Fnn=Help Fnn=Exit Fnn=Cancel Fnn=Messages
|
This screen displays the details of the physical file selected and all available logical views. For each file the name, library, description and key information is shown.
In the example screen shown the physical file is called DEMNAME and is keyed by 'Name code'. Additional logical views DEMNAMEN (keyed by 'Name') and DEMNAMEP (keyed by 'Post code') are also available and either could be selected as an alternative access path to DEMNAME.
Select either the physical file or one of the associated logical views. This step is described as 'selecting the maintenance access path' because you are effectively choosing the 'access path' through which maintenance is to be performed.
Note that the selection of the most suitable logical view (or access path) is only important when you wish to do direct record inquires or browse the file because the key(s) of the logical file influences:
- The key(s) to be specified for retrieval of record(s) from the file.
- The sequence in which browse information is displayed.
