Hi Agha Dear sirs, hello
I'm sure you meant dear sirs *and* misses :) Just two things that came to my mind, for the rest, someone with proper expertise may soon reply to you. I hope you created a new framework like explained here: http://manual.koha-community.org/3.6/en/catadmin.html#marcbibframeworks
We can’t edit the framework every time we need to add a tag or a subfield, especially which we might not use this tags with all the records we’re cataloging.
And, well yes, we should not do that... editing the framework every time we need to add a tag or subfield. But, what we *should* do is we enable all the fields we *may* need during cataloging, and when we do the cataloging, we simply leave the fields we might not need for a _specific_ record. Simple.
