In order to run bin/magento migrate:delta step you first need to run the bin/magento migrate:data step because it is in this step where the Data Migration Tool creates triggers in the source database.
Those triggers will be used to pull only the changes made in Magento 1 since the last time you migrated data.
For more information have a look to the Official Documentation.
Hope it helps.

1@jafarpinjar delta mode will only work on the same source database that you used to run migration for the reasons explained in this answer i.e., triggers are created on the source db. if you attempt to run delta on a source db that has not been used as a source for data:migrate, you will get this error.

Is there any way to continue with delta in this kind of situation? Can we move those tables from test installation into production so that we can complete delta? They seem to empty in our case so I'm not sure what is the functionality of those tables.– WebninjaNov 29, 2019 at 16:25
