I have an other class: Data-Transaction-OtherPayment. The Transactions() list contains -Payment and -OtherPayment elements. I expect the declare index rule to index only -Payment elements (because this is the source page context class) but it indexes -OtherPayment elements too.
Because of this I have to apply a filter condition in the report definition where I use this declare index to exclude -OtherPayment. How can I index only -Payment class elements?
