Hope that really answered your problem. Can also use the "Select Records" command, change the Table to the second one and add any filters you need. This will return all records in a list and using the Foreach will get the job done.

Transfer data from 2 groups with disturbance
I don't quite understand what you mean, please clarify what you want to do and what you get?
The database has been improved in the latest update. Is your problem still relevant?
Can you review the video? look at the counter. If I import new data it will go into all the groups I have.

For the old version: Import New Data will automatically create a new group named CSV. But for this new version, the data will go into all existing groups. So I will have to reclassify all data in the groups.

You can see after I import the data is present on all groups.
