Identifying closest date to another date variable

[Olga Ivanova]

Hi, i have a table with announcement date (anndat) and statistical period which is counts as a forecast period(statper) and i need to keep only statper that is closest to announcement date (anndat). How can I do this? I am a bit confused about the code i need to use.

Thank you in advance.
