Stream Control

[#1]

when using iterative macro. one of the headaches is how to stop. Generally, I is using append + filter. 

So, i create one macro for help to stop more elegant. 

you just need to connect the filter criteria to 2nd Anchor. It will stop if there have record flow in. Or vice versa.

update 18 Apr 2025:

1. add option for error message

2. add 2nd anchor for ease of data handling
