tuba2007, I am a Sage Certified Consultant.
I fixed the dayend processing error by using Rvspy.
" The problem was in ICIVAL table dayendseq no is taking -1 when i checked in IC Setup under document tab Next dayend no showing is 19, i dont understand why system takes like this?-1.so i wrote the query in the backend like UPDATE ICIVAL SET DAYENDSEQ='19' WHERE DAYENDSEQ<0
eventually dayend processing error has resolved. after 5 days again my customer complaining about the same problem. well i updated the product update 1 for 5.6A and i checked in the backend table ICIVAL again dayendseq is -1 has happend for 160 transactions so i done same thing.
so now its working fine. I am little bit apprenhensive perhaps again this problem araise in future.
Any idea? what its happening like this?
