Checking Screens
You use this procedure to check a screen for syntax errors, data consistency and layout consistency.
Screen size is measured in characters starting from the screen top left corner of the screen. The standard screen size is 27 lines by 120 columns. The maximum screen size is 200 lines by 255 columns. The system maintains the screen title, menu bar, status bar and command field separately. These are not affected if you change the screen size.
Checking Syntax
To check the syntax of a screen (attributes, screen elements and flow logic), choose Screen → Check → Syntax. If an error occurs, the system displays the error message in the status line and places the cursor on the line where the error is found. If no syntax errors are found, you can save and activate your screen.
Checking Screen Consistency
To check data consistency, Screen → Check → Consistency. The system checks for objects (fields or modules) in the flow logic or for fields in the field list which are not defined in the ABAP Dictionary or the ABAP program.
The Consistency check also allows you to check the search help, reference field, the fields Next screen and Cursor position and other attributes. In this way, you can detect errors in advance and eliminate them. The system displays the errors in a hit list.
Checking Layout Consistency
To check the layout of your screen, choose Screen → Check → Layout. The system checks whether the screen layout corresponds to the SAP ergonomic standards. The screen is checked for:
- Correct alignment and positioning of fields on the screen
- Correct positioning of group boxes
- Consistent usage of display attributes
- Violations of SAP accessibility guidelines
After performing the layout check, the system displays a hit list sorted by priority. For each error, the system offers a solution. These errors are not critical for the processing of the screen.
