    Description:
    In circulation, items tab, if you go to the Circulation Summary node and choose the 1st tab ("Current Summary") it shows "Loans: 4".

    However, the 2nd tab ("History Summary") shows "Simple Loans: 2". There is no other loan in that tab that can explain the discrepancy of 2 missing loans

    Resolution:
    This is due to conversion, and should be fine with new items (new Z30 records).

    The 1st tab has a counting that is defined in odn50/tab/pc_display_eng/item-current-summary, drawing on the parameter "z30-no-loans". The item in your example has z30_no_loans of "4". This value must come from conversion input, and was probably 2, incremented by 2 loans that occurred after switch to production.
    You can change the phrasing of this information line, or hide it, if this is bothersome.

    Remember that in the long run of ALEPH, this should be more regularly accurate.

    The 2nd tab is based on two events (Z35) of type "50", this is a "Simple Loan", as defined in odn50/tab/tab_events.eng. SQL shows that there are two z35 records.

    In our server (ram11) there is a correct match on all counting methods, and you can compare this also to new barcodes in NMI50. Below is a list built with SQL with some loans that can be checked to verify that new items work fine.

    select z30_barcode from z30, z36 where substr(Z30_REC_KEY,1,15)=substr(z36_rec_key,1,15) and Z30_OPEN_DATE > 20050201;
