I have implemented all the notes mentioned in 1478905 and then i have implemented the 1826080.
Now,when i am running the report 'NOTE_1826080_ITALY' in TEST MODE i am getting the log as,In table 'FIITC_CONFIG', 'Data Element or Structure IT_EFILING_COMM does not exist'.
During the UPDATE MODE also i am getting the same error.
Because of this err,they are three more fields SWPWD,FICAD,ACTCD needs to be created in the table is not getting created.
