-GE Lines of a Screen or a Dialog

You can replace the automatically generated error messages, declare explicit error messages, or specify help on a Screen, a Data Element or an error message.

Error
This column displays a dot on all the existing description lines which are not empty.

Moreover, if this line is not correct, this column also displays an error or warning symbol, depending on the error gravity. A hover help indicates the source of the error.

Type
After clicking the Add button, you must select one of the possible types, which vary according to the task you want to perform. You must then refer to the help specific to each task.
Description
The contents of this column vary according to the task you want to perform. You must then refer to the help specific to each task.
Link
You use this column to call a Data Element, a Segment, or a Text. If you click the icon in this field, you will be able to select an instance, which will then be automatically displayed in Description.

Click the Link field et the selection icon to display the instances available for the selected line type. Select one of them and click OK. This instance is then displayed in the Link field. To copy it out to the Description field, click the Question mark icon.

After you have specified your error and help messages, you must generate them.
