Planning on alternate resource

Hi Guys,

We have maintained main reource with non availability for 20 days.

But when system creates orders, it is placing on alternate resource considering this downtime on main resource.Means it is placing on the alternate resource  before the downtimes maintained on the main resource.

All the resources are with mode priority A and no procurement priority (infinte scheduling)

My doubt is why it is placing on alternate resource considering the down times of main resource. Why it is not placing on the main resource after or before the downtimes.

How system knows that resource capcity is reached while planning?

Thanks,

Prash

Hii Prasanth ,

Which Heuristic you are running for creation of orders ? or you are creating manually ?

If creating manually in rrp3/ppt1/rrp4 please check which  the PP strategy you are using , what strategy and setting has been assigned .

Hi Debashis,

In PP strategy setting, it is maintained with infinite scheduling and for main resource.

Eventhen it is falling on the alternative resource while running manually or in planning run (SAP_PP_002).

On what setting the system decides to fall an order on main resource considering the downtimes maintained on it (before or after) or on an alternate resource at the same time?

Thanks,

Hii Prasanth,,

What kind of PDS/PPM are u using ? R u  using one PDS with  multiple modes for alternative resource or multiple PDS ?

If you are using single PDS with multiple Modes for alternative resource.Then at the time of creation of order  it'll check whether primary resource has capacity available or not for that desired requirement period. If not it'll move automatically to second Mode. 

But that also you can control by using proper Mode selection in the strategy .

Hi Debashis,

We are using single PDS with multiple modes.

But all modes are with priority A and main resource and strategy is in infinite scheduling (so i guess it shouldnt consider the capacity)

So we expect the order to fall on main resource, but not happening always if down times are maintained in the main resource.(happening only for few products)

Could you please explain me the impact of planning and scheduling while using  Retain in Current modes in the main strategy setting and retain current mode in strategy parameters for Dep objects tab.

I put retain mode in the main setting and nothing maintained in the retain current mode in strategy parameters for Dep objects tab.Does it have some impact?

Thanks,

Prash

Hii Prasanth,

The mode priority should be different for different modes , then only it comes alternate resources with lesser priority. Otherwise the order creates will be pick up random resource with having  samemode priority .

As in your case it is A mode priority for all the resources. Might be it  is taking alphabetically the first resource for all the orders you are creating manually . It uses  GUID ...

But if your requirement is always to create on main resource , make it Mode priority A for that resource . and other alternate resource make mode priority B . and use the strategy in PP strategy to pick up only Mode priority A,  with infinite scheduling... use current mode retain ....

Hope it'll give you proper result..
