Why does the lookup work in one direction but not the other?

The lookup feature works in one direction but not the other because Clay only allows data to be sent in a linear direction (A → B → C). Loops (A → B → A) aren't possible with the "write to table" feature. If you want to send data back to the original table, you need to use either: ** Lookup Multiple Rows in Other Table ** Lookup Single Row in Other Table These lookup actions allow you to reference data from any table without creating loops.

Hey Alexandre, thanks for reaching out! Do you mind sending the link (url) to the table so we can take a closer look here?
