Defining a Prefix for Field Titles

If a field in a Master File has a TITLE attribute defined, this title will be used as the column heading for the file on report output, unless the report request specifies an AS name to be used instead.

On the segment level in a Master File, you can define a prefix for the field titles in that segment. This is useful for distinguishing which field is being displayed on report output when field names from different segments have the same title, as in the case when a base synonym is used multiple times in a cluster Master File.

Reference: Define a Prefix for Field Titles 

SEGMENT=segname, ... , SEG_TITLE_PREFIX='prefix', $

where:

segname

Is a valid segment name.

'prefix'

Is text to be prefixed to the field title on report output, for any field in the segment that has a TITLE attribute defined. The total length of the SEG_TITLE_PREFIX plus the TITLE string cannot be more than 512 characters. You can split the text across as many as five separate title lines by separating the lines with a comma (,). Include blanks at the end of a column title by including a slash (/) in the final blank position. You must enclose the string within single quotation marks if it includes commas or leading blanks.

If you generate a HOLD file with SET HOLDATTRS ON, the SEG_TITLE_PREFIX will be prefixed to the original TITLE value to generate the TITLE value in the HOLD file.

Example: Defining a Prefix for Field Titles

The following sample shows three segments from the WF_RETAIL_LITE Cluster Master File that all reference the WF_RETAIL_TIME_LITE table. The SEG_TITLE_PREFIX in the WF_RETAIL_TIME_SALES segment is 'Sale,'. The SEG_TITLE_PREFIX in the WF_RETAIL_TIME_DELIVERED segment is 'Delivery,'. The SEG_TITLE_PREFIX in the WF_RETAIL_TIME_SHIPPED segment is 'Shipped,'. 

SEGMENT=WF_RETAIL_TIME_SALES, CRFILE=wfretail82/dimensions/wf_retail_time_lite, CRSEGMENT=WF_RETAIL_TIME_LITE, CRINCLUDE=ALL,
    DESCRIPTION='Time Sales Dimension', SEG_TITLE_PREFIX='Sale,', $
   PARENT=WF_RETAIL_SALES, SEGTYPE=KU, CRJOINTYPE=LEFT_OUTER,
    JOIN_WHERE=WF_RETAIL_SALES.ID_TIME EQ WF_RETAIL_TIME_SALES.ID_TIME;, $
     ...
   SEGMENT=WF_RETAIL_TIME_DELIVERED, SEGTYPE=KU, PARENT=WF_RETAIL_SHIPMENTS, 
   CRFILE=ibisamp/dimensions/wf_retail_time_lite, CRSEGMENT=WF_RETAIL_TIME_LITE, CRINCLUDE=ALL, CRJOINTYPE=LEFT_OUTER,
    JOIN_WHERE=ID_TIME_DELIVERED EQ WF_RETAIL_TIME_DELIVERED.ID_TIME;,
    DESCRIPTION='Shipping Time Delivered Dimension', SEG_TITLE_PREFIX='Delivery,', $
     ...
  SEGMENT=WF_RETAIL_TIME_SHIPPED, SEGTYPE=KU, PARENT=WF_RETAIL_SHIPMENTS, 
    CRFILE=ibisamp/dimensions/wf_retail_time_lite, CRSEGMENT=WF_RETAIL_TIME_LITE, CRINCLUDE=ALL, CRJOINTYPE=LEFT_OUTER,
    JOIN_WHERE=ID_TIME_SHIPPED EQ WF_RETAIL_TIME_SHIPPED.ID_TIME;,
    DESCRIPTION='Shipping Time Shipped Dimension', SEG_TITLE_PREFIX='Shipped,', $

All three segments have the same fields. The SEG_TITLE_PREFIX displays on the report output and indicates which segment the field came from. The following request sums DAYSDELAYED by TIME_QTR: 

TABLE FILE wf_retail_lite
SUM DAYSDELAYED
BY TIME_QTR
ON TABLE SET PAGE NOLEAD
ON TABLE SET STYLE *
GRID=OFF,$
END

The column heading on the output shows that the TIME_QTR value is coming from the WF_RETAIL_TIME_SALES segment, as that is the topmost segment with that field name in the WF_RETAIL_LITE Master File.

To specify a different segment, such as WF_RETAIL_TIME_DELIVERED, use a qualified field name in the request.

TABLE FILE wf_retail_lite 
SUM DAYSDELAYED
BY WF_RETAIL_TIME_DELIVERED.TIME_QTR
ON TABLE SET PAGE NOLEAD
ON TABLE SET STYLE *
GRID=OFF,$
END

The column heading on the output shows that the TIME_QTR value is coming from the WF_RETAIL_TIME_DELIVERED segment.

Example: Generating a HOLD File When a Segment Specifies a SEG_TITLE_PREFIX

The title for the field TIME_QTR in the WF_RETAIL_TIME_LITE Master File is 'Quarter'. The SEG_TITLE_PREFIX for the segment WF_RETAIL_TIME_DELIVERED in the WF_RETAIL_LITE Master File is 'Delivery,'. The following request generated a HOLD file named SEGPREFIX with the HOLDATTRS parameter set ON: 

APP HOLD baseapp
TABLE FILE wf_retail_lite 
SUM DAYSDELAYED 
BY WF_RETAIL_TIME_DELIVERED.TIME_QTR
ON TABLE SET HOLDATTRS ON
ON TABLE HOLD AS SEGPREFIX
END

The SEGPREFIX Master File generated when you run this request has the title 'Delivery,Quarter' for the TIME_QTR field. This title was created by concatenating the SEG_TITLE_PREFIX value from the WF_RETAIL_LITE Master File with the TITLE value from the WF_RETAIL_TIME_LITE Master File: 

 FIELDNAME=TIME_QTR, ALIAS=E01, USAGE=I2, ACTUAL=I04,
      MISSING=ON,
      TITLE='Delivery,Quarter', DESCRIPTION='Quarter', $
