--- Comment #1 from Andreas Roussos <a.roussos at dataly.gr> ---
I managed to reproduce this: the current master I used was aa178bc.

In C4/Heading/MARC21.pm, the variable $bib_heading_fields is hardcoded.
Under the 'DATA STRUCTURES' heading there's actually a comment that
reads: "FIXME - this should be moved to a configuration file."

C4/Heading/UNIMARC.pm uses a different approach, where the same
variable is populated from the results of a SELECT statement on the
marc_subfield_structure table.

In my case, to work around this problem, I had to do the following:

1) modify C4/Heading/UNIMARC.pm as per below:

-    '650' => { auth_type => 'TOPIC_TERM', subfields => 'abvxyz', subject => 1
},
+    '650' => { auth_type => 'TOPIC_TERM', subfields => 'abcdegvxyz', subject
=> 1 },

2) add subfields $c/$d/$e to the MARC framework subfield structure
of field 150 for the TOPIC_TERM authority type.

Then, all subfields entered in tag 650 while adding a biblio in the
Cataloging module were copied to tag 150 of the new authority that
was created automatically.

But, what should we do to fix this issue for the general case?

Could we follow the same approach as for UNIMARC, and populate the
$bib_heading_fields variable from SQL data?

Or do we need a separate configuration file for this?
