You can create or modify generation elements that are related to the database on the Database Block editor -GG Lines tab. You can also complete the description lines of a Block and enter generation elements on the -GG lines that are associated with the description lines. To do so, click the -G Lines button that is available on the description line definition in the -DR Lines, -DH Lines or -DC Lines tab, according to the Block type.
You can modify or create these generation elements.
The lines that are identified by VIRT and GUID in the From column correspond to virtual lines. They are generated automatically. They guide you when you enter your generation elements. They cannot be modified directly. You must create other lines from these lines to insert modifications that will be recognized upon generation.
The variable labels and the symbolic values that are indicated in the selected Input Aid -D Lines tab are then displayed in the Description column, in a read-only mode. The Input Aid name is displayed in the Input Aid column.
When you override a virtual line, the GUID identifier turns into FromGUID and the GUID identifier turns into FromVIRT. Overriding virtual lines does not affect source lines but the lines will be copied into the target instance.
