Overwriting existing data
If data already exists for the data entry page in the year that you are updating to you will be asked to confirm that you want to proceed with the section update. If you select Yes the existing data will be deleted and replaced by the new data that the system carries forwards or backwards. Select No if you do not want to overwrite the existing data.
Example
If Mr. Abrahams had the tax years 1997 and 1998 already established and 1998 was highlighted in the list, you could choose to update the tax year back to 5th April 1997. This overwrites any data that has already been entered for the particular data entry page in 1997 and replaces it with the information that the system automatically carries backwards.
