An error occurred while trying to write to the data store . No values have been written. Details: org.hibernate.

You have columns in database which are defined as Non-Nullable. Which means it cannot be empty and looks like you have no value being saved, hence the error. Please share the DB structure and the PV data if possible.

Please see db structure:

Valuationid is not null field as it should not be empty or null.

Thanks for help.

Glad to hear that.  As an aside, please go ahead and up-vote and/or "verify answer" on any/all answers (like from me and Venkat in particular) that you found most directly helpful.

What he meant is make it NULL 

oops, yup my bad

Yes,  I am doing the same. Actually when I copied the node I forget to remove from the input tab. It works perfectly now. Thank you so much.

I kept it as it is. NOT NULL. It worked.

Yep, as long as you populate it before your first attempt to write a row, that'll work fine.  The only reason you'd change this is if you wanted to write the row and then populate the FK later for some reason.

Glad to know, It's always error from process and the way it designed . Just remember don't use write to multiple datastore entity for writing new entry when there is Parent -child relationship 

Okay, got it.

Hi Mike, I get the same error and all the FKs are NULL in my case. Can you look into this and suggest

The error message in your screenshot is something completely unrelated to the prior contents of this thread, as far as I can tell.  It's also fairly self-explanatory.

"The Write to Multiple Data Store Entities Smart Service writes multiple CDT values to multiple entities within the same data store based on your input. This differs from the Write to Data Store Entity Smart Service because you can update multiple entities within a single database transaction."
