SQL GroupBy YYYYMM over IAL fails with '(full) year must be netween -4713 and +9999 and not be 0'

@DevBob

Parse your code into this forum as text as well of screenshots. 

That worked! Thx!

Here’s the final 2 queries, followed by the results:
 

select
rega1app.INVENTORY_PRODUCT_FAMILY_API.GET_DESCRIPTION(PART_PRODUCT_FAMILY) as Product_Family,
rega1app.COMMODITY_GROUP_API.GET_DESCRIPTION(ip.SECOND_COMMODITY) as Second_Commodity,
cmo.PART_NO as Part,

trunc(to_char(OP_FINISH_DATE,'yyyymm')) finish_yearmonth,

revised_qty_due as Total_Qty_Due

from REGA1APP.CRP_MACH_OPERATION2 cmo
 left join REGA1APP.INVENTORY_PART ip on cmo.part_no = ip.part_no and cmo.contract = ip.contract

where
operation_no = '999'
and cmo.contract in ('W', 'E22')

and OP_FINISH_DATE between trunc(sysdate, 'YEAR') and add_months(trunc(sysdate, 'YEAR'), 12)-1/24/60/60

and department = '455'
and work_center_no = '45502'

order by Product_Family, Second_Commodity, cmo.PART_NO, cmo.contract, finish_yearmonth

You might want to modify your quick report SQL statement as you are hard-coding the 2020 values. So in 11 months time it will need changing again - which will no doubt be forgotten about!

Since your IAL only runs for the current year you could just use a substring?

sum(case when substr(finish_yearmonth,5,2) ='01' then Total_Qty_Due else 0 end) as January,

Otherwise if someone runs the report next year they will see 0 in every month and then just one total value in the Part Total Column
