[Koha-devel] 952$j

Our cataloguers have asked for additional precision in specific stacks -- 952$j "Shelving control number" would appear to be perfect :=) However, any value entered (eg: LLF15 -- loose leaf folder #15) systematically saves as 0 and SchemaSpy doesn't appear to even mention this field which is in the "default template" with no apparent restrictions. Can anyone with good "corporate memory" of 952$j use and programming please assist? Many thanks and best regards -- Paul
