Hi @Serge,
I understand it as following
Dataset A [Filter By Date] and you get ID’s 7627 , 9824 .
Use the result set of 7627 and 9824 in another DatasetB
Based on your example since the date has a different meaning in both datasets, you would have take the method of using actions. There is no possibility that the output of a filter from Dataset A is automatically used for filtering in Dataset B .
Again using actions, you will not be able to select all the ID’s. So once the data is filtered by date and you have the relevant values in Dataset A. You can check if the workaround in the following post How can I select multiple lines from a table? (and how could I then DESELECT those items to exclude them form the analysis?) will help you with multi selecting which will filter the data in Dataset B.
Kind regards,
Koushik
