The 090 field is INTERNAL. It's used by Koha to keep the relation 
between MARC & non-MARC tables.
If you don't set it properly, Koha won't work at all.

Note you can set the subfields of the 090 field in another place (901, 
019,...) but :
* a "9" anywhere means "local variable" in the MARC standard. So you 
should use this.
* the 2 subfields MUST be in the same field &
* mapped to tab=ignore (-1) as they are internally managed.
