BI Publisher for-each-group skip null columns in RTF template
I have a scenario in RTF template, I need to perform for-each-group based on four columns.
COL1,COL2 and COL3 can be null but COL4 will not hold null values.
When I have null values in the COL1, COL2 or COL3, I need to skip that specific column in the grouping. Grouping needs to be performed on the rest of the columns.
Please let me know how to achieve the same.
