This is a pretty old post, but I just stumbled across it, so I'll go ahead and provide some clarification.
The reason that you can only filter on one column when using the || operator is because Apptio does not allow you to mix OR and AND operators when filtering. When you filter on multiple columns, you are using an AND operator, so you can't subsequently use an OR operator in a different column. If you were to filter on one column for abc&&xyz and then a second column for 123, you would be allowed to do that because those are all AND operators.

It is working well. But it is necessary to filter only on one column. If I tried to filter on next column it was ignored. The filter on next column is colored in red so it is visible there is some problem.
