I'm facing a situation here, when I try to run MRP for an item that's discontinued.
Example: I have item X and Y. X is discontinued and Y is its substitute. I informed in MRP4 of X the subsequence with the date in the past, also the type of subesequence is "single".
Item X has a reorder point of 10 units and has 6 pieces on stock. Considering that, if I ran MRP for this item, system would create a PR of 4 pieces. Since I informed the discontinuation in MRP4, I would imagine that this demand would pass by this item and be created for Y item, the one that is substituting X. But the system did not do that.
I ran MD03 with the respective numbers: 2 - 3 - 1 - 3 - 2
Do you have any idea of what might be happening?
Thank you in advance.
