One or more cycles have been detected in database structure.

[#1]

Hi all !

I a beginner in QV. In execution time of a script of loading has received such message.

"One or more cycles have been detected in database structure. Cycles can call ambiguous results and they are necessary for avoiding. QlikView will cut a cycle (), installing one or more tables with weak links. Parametres for weaklink (??????????????) tables can be changed after script performance on page of tables of dialogue of properties of the document."

What does it mean?

Thanks

This message is occur because the link table or the database structure which you are trying to load in qlikview is become very complex because of lots of similar fields (referential + primary) in multiple table. You need to redefine the alias of the fields which you are loading.

Can you share the script which you are trying to execute so, that i can specify you where the error lies?

Sorry, I couldn't figure out where is the error actually in your code because it's in russian. Possible solution is that you need to re-check the alias of the fields that they are not repeating many times or creating complex structure because of similar field name.

Also, I am not sure that your version is supporting russian OR not. check with your vendor aswell.
