"Trailing" break lines are typically used to insert level or break totals.
As an example of this, consider the following modifications to the RDML program used in the 4.4.5 Using a Leading DEF_BREAK Command to demonstrate "leading" break lines:
GROUP_BY NAME(#ACCOUNT)
FIELDS(#COMP #DIV #DEPT #EXPEND #REVNU)
DEF_HEAD NAME(#HEADING) FIELDS(#COMP)
TRIGGER_BY(#COMP *OVERFLOW)
DEF_BREAK NAME(#BREAK01) FIELDS(#DIV)
TRIGGER_BY(#COMP #DIV)
TYPE(*LEADING)
DEF_BREAK NAME(#BREAK02) FIELDS(#DIV #DIVEXP #DIVRNU)
TRIGGER_BY(#COMP #DIV) TYPE(*TRAILING)
DEF_LINE NAME(#DETAILS) FIELDS(#DEPT #EXPEND #REVNU)
DEFINE FIELD(#DIVEXP) REFFLD(#EXPEND) LABEL('Expend')
DEFINE FIELD(#DIVRNU) REFFLD(#REVNU) LABEL('Revenue')
SELECT FIELDS(#ACCOUNT) FROM_FILE(ACCOUNTS)
KEEP_TOTAL OF_FIELD(#EXPEND) IN_FIELD(#DIVEXP)
BY_FIELD(#COMP #DIV)
KEEP_TOTAL OF_FIELD(#REVNU) IN_FIELD(#DIVRNU)
BY_FIELD(#COMP #DIV)
PRINT LINE(#DETAILS)
ENDSELECT
ENDPRINT
Note how the DEF_BREAK command is "triggered" by change of #COMP or #DIV. Note also the KEEP_TOTAL commands into the SELECT loop. These are used to automatically keep the company/division subtotals. Refer to the KEEP_XXXXX command series for more details of these commands and their usage.
The resulting report, using default design attributes, would probably look something like this:
Company 01
Department Expenditure Revenue
Division 1
ADM 400 576
MKT 678 56
SAL 123 6784
Division 1 Expend 1201 Revenue 7416
Division 2
ADM 46 52
SAL 978 456
Division 2 Expend 1024 Revenue 508
Division 3
ACC 456 678
SAL 123 679
Division 3 Expend 579 Revenue 1357
Company 02
Department Expenditure Revenue
Division 1
ACC 843 400
MKT 23 0
SAL 876 10
Division 1 Expend 1742 Revenue 410
Division 2
ACC 0 43
Division 2 Expend 0 Revenue 43
However, by using the Report Design Facility in the LANSA for i User Guide, the entire report layout could be modified in a few minutes to look like the examples following.
Company 01
Department Expenditure Revenue
