Version of Knowledge article

[Christopher096]

As part of my requirement, I need to change the knowledge base of few published knowledge articles. So I created an fix script to update the knowledge base. After running the fix script, articles got updated with expected knowledge base. But the version field of all those articles got empty. Before that it has value. Even I checked the audit but not showing any updates related to version. I tried to rollback all records but still version showing empty. May I know the reason for it?

Versioning is done through the kb_version table, so that field is a reference field. 
How it happened? You will have to share the code you ran to enable us to give an answer to that, since we can now only guess to 'your code did this'.

Please find the fix script which I used for this:
