Data Display Screen—DLOD (or) DDIS

Description

A Data Display screen is formatted by ASF for each data table for which an application is generated. The Data Display screen lists the columns in the table that were included in the screen display, along with response fields that allow you to display, load, change, and remove data.

ASF formats the Data Display screen for a table by using a model map. Though the model used at your site may have variations, the model generally used allows 32 characters for each column name and begins each column name on a new line; response fields for the columns are allocated based on the width (or external picture) of the column. When formatted, the Data Display screen lists as many columns and their appropriate response fields as can be displayed on the terminal screen. If the Data Display screen formatted by ASF is inadequate for displaying a particular table, you can modify the Data Display screen manually by using the online mapping facility.

Access

You can access the Data Display screen for a particular table in the following ways:

• Select the Load Data function from the Activity Selection screen; you can select the function by pressing [PF3]. When accessed through the Load Data function, the Data Display screen displays the column names so that you can enter new data online, one row at a time.
• Select the Display/Change Data function from the Activity Selection screen; you can select the function by pressing [PF4]. When accessed through the Display/Change Data function, the Data Display screen displays the column names and one row of data at a time. You can display, add, change, and remove data from the table.
• Specify selection criteria on the Data Selection screen and press [Enter]. The Data Display screen is displayed automatically. When accessed through the Data Selection screen, the Data Display screen has the Display/Change Data function, but displays only those rows that meet the selection criteria.
• Enter DLOD or DDIS in the screen name field of any screen. When you enter DLOD, the Data Display screen has the Load Data function; when you enter DDIS, the Data Display screen has the Display/Change Data function.

To leave the Data Display screen, press [Clear]. This returns you to the Data Selection screen if the Data Display screen was accessed from the Data Selection screen, or to the Activity Selection screen if the Data Display screen was accessed from any other ASF screen. Note that the Data Display screen is part of the application created for the table and is not actually an ASF screen. Therefore, the Data Display screen does not have a screen name field that can be used to move to any ASF screen. When you leave the Data Display screen, you must return to the prior ASF screen.

Fields

The fields on the Data Display screen vary according to the model used to format the screen and the columns included in the individual table. Generally, the Data Display screen contains the following information:

• Heading information is displayed according to the screen model in use at your site.
• Message text is displayed, providing instructions and information on the use of the Data Display screen.
• The table name of the specified table is displayed.

The remainder of the screen contains a sequential list of columns in the table. If the Display/Change function applies, the screen will also display one row of data. No data is displayed for the Load Data function.
