Using the statistical value in the cumulated formula 036

Dear Experts,

I want to use the statistical value the instead of the Net Value. Also I looked point 9b in the note 844141 from ECC. We understood that we needed to use the statistical value (XWORKM, for example) instead of the Net Value.

We created a copy of value formula 036 in the customer namespace (936). The replace the line ICurrencyValue netValue = pricingItem.getNetValue() with

ICurrencyValue netValue = pricingItem.getSubtotal(PricingCustomizingConstants.ConditionSubtotal.SUBTOTAL_M) in the copied formula 936.

Unfortunately the formula 936 did not work.

Please help me,
Alex.
