In Bi Publisher , this is a very common requirement to set a variable in RTF template to do some data manipulation activities.
Set variable is used to declare the variable in the BI publisher reports. We need to declare the variable first and then initialize with some value. Set variable helps to Declare and initialize the value to the variable in the XML/BI publisher report.
Some examples are to set a Running Total in BIP , Count Records in a Group etc.
Steps to add a variable in RTF
- From the bi publiser menu in word insert the form field in RTF and add below code in the form field.
- Make sure Variable form field is outside the grouping loop.
- Add the below codes for each of the variables in its form field help text.
<?xdoxslt:set_variable($_XDOCTX, 'counter', 0)?>
<?xdoxslt:set_variable($_XDOCTX, 'lines_page', 4)?>
<?xdoxslt:set_variable($_XDOCTX, 'tot_lines', count(.//G_SLNO))?>
<?xdoxslt:set_variable($_XDOCTX,'remainder',0)?>
The above code will create variables counter, lines_page, tot_lines, remainder
G_SLNO is the example group name.
- Call the below code in form field before end the loop (Inside the loop)
xslt:get_variable($_XDOCTX, ‘lines_page’) <= 0?><?call:breaking?><?end if?><?end if?>Running Total Variable in BIP
- For taking Running total, use below code.
- Make sure Variable outside the loop.
- Add the code in the form field.
<?xdoxslt:set_variable($_XDOCTX, ‘counter’, 0)?>- call the below code in form field before end the loop (Inside the loop)
xslt:get_variable($_XDOCTX, counter + <ColumnName>) <?end if?>Column name is the field you want to have a running total.
