How To Fix M3137 - The new price unit causes rounding errors in the standard price

SAP Error Message - Details

• Message type: E = Error

• Message class: M3 - Material Master

• Message number: 137

• Message text: The new price unit causes rounding errors in the standard price

What causes this issue?

When the price unit is changed, all prices of the material are
recalculated. When calculating the standard price, the system detected
a rounding error. This means that the valuation price does not exactly
correspond to the stock value (possibly multiplied by the price unit)
divided by the stock quantity.
<ZH>Example</>
Stock value,,,,$10,001.00
Price unit,,,,10
Stock quantity,,5,000 pieces
Dividing the stock value (multiplied by the price unit) by the stock
quantity results in a valuation price of $20.002. However, since the
price in dollars is rounded to two decimal places, the valuation price
determined by the system is $20.00, that is, a rounding error occurs.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
