Hello, TL;DR = When importing MARC records, items don't import and fail. I am transitioning from Follett Destiny to Koha. After doing a MARC export from Follett, I noticed that when staging records for import, Koha would parse the biblio records fine but wouldn't find any item records. After searching past messages in this list, I found that Follett has item records as 852 instead of 952. I used MARCedit to change those to 952 and also added a and b records to match the libraries listed in Koha. After doing that and trying again, item records were then found during staging. However when I import the staged records, it just fails and gives me nothing in the detailed messages in the UI. If I remove the 952 records, it works fine and imports all the other records thus I know something is wrong with my 952 entries. I have checked that there are p barcodes and a and b home and current libraries. In the Koha logs on the server, this is the only error message I get when I try to run an import and it fails. To me it seems like a FK is missing on import but I don't know what. Looking at the schema example, I'm wondering if I'm supposed to be importing things to 942 and 999 along with 952. I do not know if, when importing MARC records, Koha creates its own enumerated ids for biblio, item number, etc. if that stuff isn't in the import file... or if it isn't there, will it fail?

Here are a couple of 952 records from the Follett export to Koha import file to see if something simple is wrong. I'm hoping it's something simple on these lines. =952 \\$p34517100010472$aPRBHS$bPRBHS$bStory Collection$v10.00USD$x14441$eaRegular@c20060929@fTransfer from PRB Elem.@j @j@j@i@i@i$hSC Otf$x1127380 =952 \\$p3333300007200O$aPRBHS$bPRBHS$v20.00USD$x17292$eaRegular@c20050604 @j@j@j@i@i@i$hR 639 Can pb$x527111 (Beyond that, I haven't really tinkered with anything in the default MARC framework settings in admin.
