You will now be presented with the auto-generated Komment load script as shown below.
Initialize Data Model
Initialize Data Model. Komment will now automatically inject the script in your Data Load Editor and do a reload of the application.
That's it! You have now successfully configured your write-back solution.
Qlik Engine has a known issue that can occur when initializing the data model. This error warning can safely be ignored as the data model will be initialized correct.
If you want to externalize the Komment script section and use variable based path, you must ensure that the variable is not cleared out after must_include/include function:
//Set script path
LET vScriptPath = ‘lib://myScriptFolder’;
//Include komment logic in qvs file
LET vScriptPath = ‘’;
In above case, Qlik will run into an error when reloading. That’s because Qlik will firstly execute the ‘Clean variables’ part rather than ‘Include’ function. So the suggestion is to either move the clean logic into a qvs with include or remove it if not necessary.
