My goal is to insert some list items in a second BCS list. When I try to do a create item and just use static values it writes into the BCS list with no errors. As well I can create another workflow that queries the first list and puts IDs in a collection variable, which I then run through a for each. So when I just send each of those list item's values to myself in a email it works great. But when I try to combine these two I get errors every time. The error I get is:

The workflow could not create the item in the external data source. Make sure the user has permissions to access the external data source and create items.
