Duplicate PPDS orders

[Former Member]

I currenlty see duplicate planned orders being generated by the system( as part of nightly heuristic job only on some days) in certain cases. These have been far and few but I am having trouble understanding what may be causing this.

When I go into the product view , I see Dependent Demand of 100, and 2 planned orders for 100 covering the demand of 100. this has happend for every requirement. The first planned order has a status of planned order NC(checked, fully confirmed) which is nothing but a planned order on which an availability check has been done. The second planned order does not have this status. When I try to manually run the product heuristic, the plan again adjusts itself by deleting these duplicate orders.

Can anybody think of any reason why this may happen?

Appreciate your help!

Hi,

In the product view RRP3, enter gt_io in the space where you enter transaction code and press enter. This takes you to the Live cache view. This is also what you see in OM16.

Now, check if both the orders have the same start date and close by creation times.

What I suspect is that your previous run orders are not getting deleted before the next run.

I am a little surprised that the system is creating double orders for the same requirement. Usually the system does net requirements calculation and if the system sees a order that satisfies the demand, it does not create another order for the same demand as the equation is already satisfied.

Varun,

Please check in MD04 whether order is there or not?

Run CCR if it is not there.

Also check through /SAPAO/OM16 when this orders are created and correlate with your Planning run timing..

Also check whether any other jobs are running at that time of creation of order through sm37 and check SLG1 log at the time of order creation .

It will certainly give you some clue about the root cause of the problem.

please check if you are observing this behavior on certain products every time Heuristics job runs. if so please check if the job is running twice every time and also for those products check if "Fix Production"(SNP2 tab) box is checked in. also check in MD04 if you see any duplicate entries
