of anyone item, and it must only appear at the elementary level.

{
; SOURCE IS identifier-1 }
; SUM identifier-2 [, identifier-3] ... [UPON data-name-1]
; VALUE IS literal-1
The identifiers must identify an item in the File, Working-storage, or
Common -storage Sections; a sum counter in the Report Section; or one of
the special registers: SYSTEM-DATE, or SYSTEM-TIME. The literal in
the VALUE clause may be numeric, non-numeric, or a figurative constant.
Data-name-1 is the name of a detail report group; it may be qualified by
report name if the name is used in more than one report description. SOURCE
and SUM are described below; VALUE is described in chapter 3.
The SOURCE clause indicates a data item used as a source for the report
item. PICTURE must also be specified in the entry for the report item. The
value of identifier-1 at object time is effectively moved to the report item and
presented according to the PICTURE speCified in the report item description.
The fixed data items LINE-COUNTER or PAGE-COUNTER may be specified
as identifier-I; in this case the current value of the line counter or the page
counter is the source.
