Step 1: The variable hlf0069_h is replaced by the variable hlf0069_v5 for the years 2002 to 2014 and 2016 to 2022. Step 2: The variable hlf0069_v4 is converted into Euro by divisor 1.95583 (not adjusted for inflation) for the years 1991 to 1995 and subsequently integrated into the harmonized variable hlf0069_h. Step 3: The variable hlf0069_v1 is converted into Euro by divisor 1.95583 (not adjusted for inflation) for the years 1986 to 1989 and subsequently integrated into the harmonized variable hlf0069_h. Step 4: The variable hlf0069_v1 is converted into Euro by divisor 1.95583 (not adjusted for inflation) for the years 1997 to 2001 and subsequently integrated into the harmonized variable hlf0069_h. Step 5: The variable hlf0069_h is replaced with -2 for the years 1990 and 1996. Step 6: The variable hlf0069_v3 is converted into Euro by divisor 1.95583 (not adjusted for inflation) for the year 1990 and subsequently integrated into the harmonized variable hlf0069_h, if hlf0069_v3 is greater than 0. Step 7: The variable hlf0069_v3 is converted into Euro by divisor 1.95583 (not adjusted for inflation) for the year 1996 and subsequently integrated into the harmonized variable hlf0069_h, if hlf0069_v3 is greater than or equal to -1 and hlf0069_v2 is less than or equal to -1. Step 8: The variable hlf0069_v2 is converted into Euro by divisor 1.95583 (not adjusted for inflation) for the year 1990 and subsequently integrated into the harmonized variable hlf0069_h, if hlf0069_v2 is greater than 0. Step 9: The variable hlf0069_v1 is converted into Euro by divisor 1.95583 (not adjusted for inflation) for the year 1990 and subsequently integrated into the harmonized variable hlf0069_h, if hlf0069_v1 is greater than 0. Step 10: The variable hlf0069_v2 is converted into Euro by divisor 1.95583 (not adjusted for inflation) for the year 1996 and subsequently integrated into the harmonized variable hlf0069_h, if hlf0069_v2 is greater than or equal to -1 and hlf0069_v3 is less than or equal to -1.
