Hi @Søren Sørensen 

I searched through old tickets and found the following.

This is to handle illegal characters in table names when using ADO as transport.

I also found this explanation.

From what I can see in the code, BCV views are used when a NAV table contains a dot (.) in it's name.
That apparently can't be translated directly, so it needs to be replaced by an underscore (_) and then the view gets a postfix called _BCV.

Are you using a NAV adapter data source for this?

Hi @Thomas Lind 

I’m using a CData CSV data source that scoops up a bunch of files with “.csv” (i.e. a dot) as suffix.

Converting dots to underscores (like NAV data sources) is fine … what’s strange is, however, that they always need deployment even though nothing has changed.

Also, the clean-up tool deletes the tables … and then they surely need to be redeployed 

Thanks, Søren

Hi @Søren Sørensen 

What version are you in?

It only does this when you do differential deployment, not when you use the Deploy Only modified tables and views, right?

You can resolve this by removing the .csv part of the table name.

Nice, thanks @Thomas Lind 

I’ve never noticed this setting … that’ll surely fix the issue.
And yes, it’s only when doing differential deployment.

Hi @Søren Sørensen 

Good. I tried to see if it behaved the same for me, but it does not work like that.

So it will be more than just it being in version 20.10.43 and having . in the name.
