Group Lines

This type of line is used for defining a repeating group of standard lines. This line contains header information about the group. Every line that belongs to the group refers to their group line.

Determine whether or not recurrence should be limited to a finite number.

Refer to the definition of business object C1-GroupLine for more details.
CAUTION:
Although the configuration allows for unlimited recurring groups, the HTML rendering for the user interface is unable to handle a large number of repeating groups. Be careful in using forms to capture data that results in a large number of lines. Such forms need to be fully tested with expected volumes, to ensure that the forms are able to handle your business need.

Also, nesting of groups (i.e. groups within groups) is not supported.
