Transacciu00F3n MFN1 - Error KA465: Production order with an actual activity up

Hi Exerts,

I am executing transaction MFN1 with "Update of Activity Consumption in the Quantity Structure" = 2 and the following error ocurrs: "KA465 Production order with an actual activity update.".

I changed the customizing "Update of Activity Consumption in the Quantity Structure" to "Activity update not relevant to price determination", after this I exectuted transaction MFN1 again and the error didn't occur.

I need to understand what is the impact of changing this customizing, and if I set the "Update of Activity Consumption..." equal 2, the activity actual values are revaluated in the CKM3N? If the answer is yes, in what point of the CKMLCP this value is revaluated?.

Regards
