Hello,

Suppose that with COM you have a Filesautomation.
I've seen that if you have a bunch of files with the same "the TVDB Series ID" tag, if you just change this tag in ONE file, ALL the files are updated .
But if I change the serie name, just the concerned file will update.
It seems that the same behaviour happens when tagging some tag in Album -> some tags if set on ONE file, will automatically affect the other files ..

I think that's a logic behind all that, but can't understand why this was implemented this way ? May do i not have the skills to understand correctly this behaviour.

So, the basic question is : which tags do have this behaviour ?  ? because if I want to modify some tags, I should be aware which other files will also be affected.

Please excuse my bad english, hope I can be understood.

[theTVDB Series ID] is a Relational field, which stores a single value for each [Series]:



Most fields are non-relational, meaning each item in the Library has its own independent value.  However, fields can be made that are relational, keyed off of one of:

* [Series]
* [Artist]
* [Album]

Thank you very much, Glynor.

I haven't seen the relationnal field and to say it all I didn't know there' s such thing : i knew about the "calculated" field  type, but not the "relationnal" one.
So yes, this brings me a step further.

I've browsed the entire existing fields in MC : the only default one I have which is actually relationnal is ..."The TVDB Id Series" ! 

But, I must put some more effort , because I've seen another case where MC seems to modify "internally" field values - when I was trying to make a plugin which assigns a incremental number to each different album :maybe am I completely way off the mark, I must recheck my code -the problem must be there ...

Thanks for your time!
