When using the MRP_SCHEDULE_INTERFACE, how do I get the Planning Manager to REPLACE the data from a

We are using ASCP and need to feed that with a Supply Plan. The data comes from another source.

We want to load this into an MPS, so ASCP can see it as Supply.

I load the data via the MRP_SCHEDULE_INTERFACE. That works fine.

BUT: when I want to refresh my data, each time I load again the data gets ADDED to the MPS, thus doubling/trupling etc.

With "Load/Copy:Merge there is a paramter that allows to "Replace All"/"Add"/"Replace same source only"

I want to do the first (or the third, in my case the result is the same), when I, for example, one month later, want to refresh my data.
