Automatic Field Calculation in Material Master from another t-code

[khaled4700]

Hey Guys,

we changed the standard calculation for automatic reorder point to be for 2 months coverage not for the replenishment lead time coverage for that, we used the user exit in the sap note
SAP Note 351240 Customer-specific calculation of reorder point-safety stock

part 2 of the solution they wanted that when the stock falls below the reorder point you have to replenish to a stock level that covers 4 months

the developer automated the calculation of the max stock level to be equal = (2 * AROP - 2 safety stock) + average daily usage * RLT

this calculation is only triggered when you press "execute forecasting" in the forecasting view in the MM01 t-code my issue now is

it's not calculating max stock level when I use MP30 (individual forecasting ) or MP38 (total forecasting) they only calculate the automatic reorder point

How to fix this ?
