Step 1: The variable plb0186_v2 is divided by 10 in order to fix incorrect values resulting from previously lost commas or unit changes and subsequently integrated into the harmonized variable plb0186_h for the years 1998 to 2020, if plb0186_v2 is greater than 0. Step 2: The variable plb0186_h is replaced with plb0186_v2 for the years 1998 to 2020, if plb0186_v2 is less than or equal to 0. Step 3: The variable plb0186_h is replaced with plb0186_v3 for the year 2022, if plb0186_h is -5 and plb0186_v4 is less than or equal to 0. Step 4: The variables plb0186_v3 plb0186_v4 of which one expresses the value before the decimal point, and the other the value after the decimal point are combined for the year 2022 and subsequently integrated into the harmonized variable plb0186_h, if plb0186_h is -5 and plb0186_v3 is greater than 0 and plb0186_v4 is greater than 0. Step 5: The variable plb0186_h is replaced with -2 for the year 2022, if plb0186_v3 is less than 0 or plb0186_v4 is less than 0. Step 6: The variables plb0186_v3 plb0186_v4 of which one expresses the value before the decimal point, and the other the value after the decimal point are combined for the year 2022 and subsequently integrated into the harmonized variable plb0186_h, if plb0186_v3 is greater than or equal to 0 and plb0186_v4 is greater than or equal to 0.
