SAR request only covers 5 years plus some information is not accurate

[Art87ee]

My SAR only covers the previous 5 years even though I had requested data from the time I began living in the UK. Is this an error or do they not provide data for a longer period?

Also, some information about my applications is incorrect (wrong dates). Can this be corrected?

I just noticed that it is possible to ask for a 'detailed' SAR for more information. Will that cover a period of more than 5 years?
