PPDS not reducing order duration if capacity is increased

[krishna_chandra5]

Hello everyone,

We are using SCM 7.0 Version and we are facing an issue in the below scenario in PPDS.

We have a multi-mixed resource (labor constrained planning) with no. of capacities as 1. But for some days business will increase the labor capacity for which I have changed it in the resource capacity profile for that specific day to 10.

For eg: Business can produce 10 FG in 10 hours with 1 labor, if they increase the labor to 10 then they can produce 10 FG in 1 hour as there is more labor.

But when we are running the planning in PPDS, it is not reducing the duration of the order, instead it is scheduling multiple orders in the resource for that day as there is 10 times more available capacity.

This is not the case in ECC MRP planned orders, where it is reducing the time for orders on that day if I increase the no. of capacities in the work center.

Not sure if my expectation is wrong or if am I missing anything here. Any help is really appreciated.

Regards,

Krishna Chandra

Hi Krishna,

There are two aspects here a) is available capacity which is maintained in the capacity i.e. plant-capacity level/dimension b) The capacity consumption which is captured in the PDS at product-plant-resource level. You may have 5 capacities available for labour but whether all the 5 are being used for consumption in producing a product is a different proposition for which you are planning to use number of splits. If you want that to be the logic then you need to use validity dates of the production version in line with the capacity profile validity dates to reflect splits and consumption patterns across all the products which are running through the resource. Please note these are all based on master data which ideally i would not expect to change frequently. Even if you try to influence the PDS BADI you would need change numbers to support validity dates to influence the consumption patterns over a period of time.

I hope its clear.

Thanks again for your response Sasi.

Firstly the available capacity at the ECC WC capacity level and APO Resource level are the same and I am clear on that part.

Coming to the splits maintenance, we also gave thought about maintaining routing with different validity dates with reference to change numbers, but as you have already mentioned it is not suggestable and make the scenario more complex.

Based on my analysis and understanding, below is the difference in the scheduling behavior between the two systems. I am curious to know why there is a difference between ECC and APO order scheduling. Please throw some light on it if possible so that I can understand it better.

ECC behavior: While scheduling, the system will consider the routing activity time along with the no. of capacities I maintain in the WC. It will increase/decrease the order time if I maintain a new interval in the WC interval shifts and increase/decrease the number of available capacities. The prerequisite for considering splits is to tick the "Splitting Required" in the operation detail of routing.

APO behavior: While scheduling, the system is considering the PDS activity time and not considering the no. of capacities I maintain in the capacity profile of resources or in the ECC WC. The prerequisite for considering splits is to tick the "Splitting Required" and also no. of splits in the operation detail of routing. As it is considering the routing splits, there is no flexibility to maintain the splits per date or shift in resource/WC similar to ECC.

Hi Krishna,

The reduction of duration is not dependent on the capacity of the work center. It depends on the consumption values in the PDS. Please check the duration values in the PDS and the system will behave accordingly.

Hope this is clear.

Thanks for your response Sasi.

I understood the concept of PDS Activity Duration (Var.) which will get reduced if I maintain the no. of splits in the Routing operation detail. But my requirement is more about the dynamic labor/split count for every day which I can't maintain in the routing with reference to dates.

I am expecting the system to consider the no. of splits maintained in the capacity profile of the resource. So that the business can maintain the no. of labor specific to the day and shift and the orders will be scheduled accordingly specific to the daily splits.

Any idea how this can be achieved (standard/custom)?
