Delete all data is a requirement of the client.

I found the solution. The smart service "Delete from Data Store Entities" doesnt work for me, I used "Query Database" and I write in SQL the sentences Delete from * ...., and it works.

Thank you everybody.

Taking a step back, what is the overarching use case? I'm confused as to what the scenario would be where you commit something to the db only to wipe it every time you start the process.

It is a specific field with CDT, but it has multiples values, like:

Directory:[
[address: Madrid, Number:2],
[address: Ciudad Real, Number:3]
].

It has CDT and Data store, and I just want: when I will start the process, delete every data of Directory and have empty my database of Directory.

Depending on exactly what you mean by variable there are different methods:

If by 'variable' you mean a simple process variable, then it is not a data store entity and so instead of using the 'Delete from Data Store Entity' you should simply use a script task to write null into that variable

If you are referring to a specific field within a CDT, the same advice applies. The 'delete from data store entity' actually removes the row from the db, meaning that there is nothing to update after running it.
