Which operations would you use in a personnel calculation rule (PCR) called by function PIT...

AMT 0.90: This multiplies the amount of the current wage type by 0.90, effectively reducing it by 10%.

ADDWT*: This adds the reduced wage type amount (along with its number) back to the input table (IT), making it available for subsequent calculations or processing.

Why other options are incorrect:

AMT 0.90 ADDWTI:* The 'I' at the end signifies that the result will be stored in the internal table, but not passed back to the input table (IT) for further processing in the current schema.

AMT 0.10 ADDWT* / AMT 0.10 ADDWTI*:** These would reduce the wage type by only 1%, not 10%.
