Hi Experts,

I have a situation where the MRP Run for a material(MD02) shows incorrect procurement proposal quantity. The Lot size selected is "4 week Lot Size", expectation is that the MRP run should consolidate the 4 weeks of forecast quantity and create a purchase requisition, after rounding based on the "Rounding Value". what is happening is for the 1st purch requisition it shows 4 week quantity and for the 2nd & 3rd requisitions it shows 5 weks and 1 week quantity as shown in the screen shot,please advise!

you need to check that material master record properly especially MM03: MRP1 -MRP4 tabs.

for example, compare data with another material which "is shown in MRP correctly"

Hello

Can you provide us details about the lot sizing procedure and the rounding defined for your material? If possible, please add screenshots of tabs MRP 1 and MRP 2 and the lot sizing customizing.

Regards,

Caetano
