Hello!
When you send a list to have something done … that same “something” happens to each item of the entire list. This is why all your proveedores are getting the same “count+1”.
If you want something different done to each proveedor, then you need to build logic for this different “something” to happen to each single entry.
I suggest you consider using schedule api and not schedule api on a list and set everything up in a somewhat similar fashion to this:
The above is a “loop” with an extinguishable condition (aka as a recursive flow).
Hope this helps
