I do believe BAQ reports have been deprecated. They are basically BAQ based RDD reports with just one BAQ so probably won’t totally go away. Existing ones would likely continue to work even if the BAQ Report Designer is totally removed but I’d really like to see them expand that to support “BAQ based RDD” reports instead as a one-stop-shop for all BAQ based reports.
I have been calling the BAQ based RDD Reports “Dynamic Criteria” reports. (since that is the name of the dll that runs them".
I agree with @Vinaykamboj. The “Dynamic Criteria” reports are a little trickier to setup i.e. more steps that are NOT intuitive, however being able to use multiple BAQ’s is HUGE.
I keep hoping that Epicor will refine the setup some day - but after YEARS of trying to make one monolithic dataset work for every report - I welcome the Dynamic Criteria option.
