I'm still having the issue with JDeveloper 188.8.131.52
When set the aggregation for the pivot table, one column should be summed but others should not.
So I set the default aggregation to SUM but in the Attribute-Level Overrides set others columns to aggregation type = "NONE". However, when running the table, these none summed columns showing empty rather than showing the actual data value.
Found a previous archived issue with the same problem but not answered.
Can anyone helps please. Thanks.
