Fix pegging does not work with std lots heuristics in ePPDS

[nkharod]

I set up fix pegging in Advance planning view of MM02 for the products and ran std lots heuristics. But the orders are not getting fixed pegged to sales orders demand nor the planned orders of dependent demand are getting fixed pegged to higher level planned orders

I am using ePPDS in S4 system (1809)

Any idea to get this working?

Thanks
