I want the following results:

So, I want to fill the Titleann and age column. Some of the missing observations will be filled based on previously given information(yellow colored one) and some of the observations will be filled based on the later information(green colored one). And It is not possible to fill some of the missing values as there is no previous and after values are given for those. Missing values will be filled based on "EXECID" Also, GVKEY and FYEAR are important because the same executive may serve in different companies in different year. Can anyone please help me by giving the code?

Use a double DO loop to determine the necessary values per execid. The dataset has to be sorted by gvkey and fyear.

data have;

Note how I created the example dataset with a working (no ERRORs, WARNINGs or extraneous NOTEs) data step with datalines; please provide data in this form in the future, as it makes it clear what is contained in your data with respect to variable attributes and contents.

This is how logs from clean steps look:
