Step 1: The variable plb0176_h is replaced by the variable plb0176_v3 for the years 1998 to 2020, if plb0176_v3 is less than or equal to 0. Step 2: The variable plb0176_v3 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 plb0176_h for the years 1998 to 2020, if plb0176_v3 is greater than or equal to 0. Step 3: The variable plb0176_h is replaced by the variable plb0176_v5 for the year 2022. Step 4: The variables plb0176_v5 plb0176_v6 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 plb0176_h, if plb0176_h is -5 and plb0176_v5 is greater than 0 and plb0176_v6 is greater than 0. Step 5: The variable plb0176_h is replaced with -2 for the year 2022, if plb0176_v5 is less than 0 or plb0176_v6 is less than 0. Step 6: The variables plb0176_v5 plb0176_v6 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 plb0176_h, if plb0176_v5 is greater than or equal to 0 and plb0176_v6 is greater than or equal to 0.
