Heuristic Issue.....Period Lot size not working

Hi Gurus,

I am new to Heuristic, my requirment is monthly generation of PRs on the the basis of Planned delivery time.  For Eg. Planned delivery time is 120 days

Demand :-  1March - 100

                   1April -120

                   1 May - 120

Total Demand  - 340

Now wat Heruistic is doing, Since Planned delivery time is 120 days it cumulate all demand 340 and generate P.R on 25th May.  I dont want this result.  The result should be

25h May 100, 25th June 120, 25th July 120.

Am i missing some setting in master data or something else is left out.  For Information i maintaint the fiscal year variant in Storage bucket profile

Immediate respone is highly appreciated.

    Hi Rajesh,

    Thanx got ur point

    Now another issue, i Had maintained Period Factor as 0.500. So the PR Generation should be in the middle of the month, but while running Heuristic it create PR on running Date+120 days delivery time.  Am I missing some settings

    Thanx in advance

    Hi AJ,

    SNP heuristics considers the planned delivery time as horizon (if SNP stock transfer horizon is less than PDT) and hence, creates the receipt element immediately after the horizon to meet all the demands within the horizon.  However, the demands after the horizon will be processed in time-phased manner. Heuristics supports period lot size procedure (except the one based on planning calendar).

    Per your description, the dates are not matching and hope you would have maintained the fiscal period variant even in the time period profiles of your data view.

    If it's still an issue for you, pl share your planning book/data view screen shot of your heuristics results covering at least 6 to 7 months (going by your PDT as 4 months) with demands in each period.
