When a SAS LASR Analytic Server query uses an IN statement with more than 10 elements, query performance might be negatively impacted. For example, you would see this performance impact in SAS^® Visual Analytics if you used such an IN statement in a filter or a calculated data item.

As a workaround, split the IN statement into multiple IN statements that each contain fewer than 10 elements, and then use an OR statement to combine them.
