ePPDS Variable Resource capacity consumption

[scm_09]

Hi Gurus, Got couple of questions on this

we have a scenario where multiple materials need to be baked in an oven. baking time is fixed, but oven can only handle 50 pcs at a time. so, my oven capacity is lot size dependent and I created it as Multi activity resource with one capacity. when I transfer the pds, I only see fixed consumption as 1 in capacity requirements. How can I get Variable resource consumption? what are my options? I read somewhere that I need to use some PDS badi to populate two things..one is capacity field in the resource master and one is rescons(v) field in the PDS..

my requirement we have material A - order 10 pcs, material B - order 30 pcs, material C - order 10 pcs.. I should be able to schedule all these 3 orders in he oven at the same time as the capacity of my oven is 50 pcs..

my questions are

1. in the example above, what should I populate in rescons(v) and what should I populate in capacity field of resource master

2. why SAP did not give this as standard. why we need to use BADI? in SAP help it clearly says that we can use variable consumption for multiactivity resources.. but when I try it does not populate the values..any technical reason?

Thanks

Hi,

Single activity means at a time you can process only one activity in other words you will be able to handle only one activity of the order at a time i.e. either setup or produce activity. In simple terms the machine can handle one order at a time so if you have activity as 1 it can never be a multi activity. You would need to define your capacity as multi activity with the capacity of the furnace as say 50( as you have defined in the example). This shall enable you to schedule all the orders of material A,B,C inside the furnace at the same time. In the PDS BADI you would need to define the variable consumption as to how much capacity will A occupy of the 50 available capacity based on your base quantity. This shall help you to load the oven accordingly, similarly for B and C. Make sure all these materials have the same fixed duration. You would need to model like this, so that you can handle multiple orders together.

The same is explained in my blog.

Thanks.. so in capacity field in resource master I will update as 50 pc as the capacity..

For Material A, we can bake all 50 pc in that oven within 1 hr.. similarly, we can do the same for Material B and C.. duration is fixed (1 hr) but the capacity is 50 pc max.

So, rescons(V) field in PDS for material A should say 50? also same for Material B and C PDS? (Please help me on what value should I fill in for my scenario above or logic/formula to be used to come up with a number)

My requirement is if I have a order of 10 pc for material A, 30 pc for material B and 10 pc for material C, I should be able to schedule those 3 orders in that oven at a time..

Also, the F1 help on it says that this field will be used in multi mixed/activity resources.. but its strange that we are not able to fill that field in standard way (using capacity req formulas in CR02) other than the badi way?

any help is appreciated eeee36c5ca424a59973fd7fa9ff786e2 or other experts.. thanks in advance

Hello Sasi, Which Badi we should use inorder to consder Variable Resource Consumption?

[Sasi2005]

Hi,

I suppose this is a similar question to the one i had answered https://answers.sap.com/questions/13154110/variable-capacity-consumption-in-eppds.html

SAP standard is to have fixed resource consumption (Capacity requirements) and variable duration(Mode). In this case you are planning to change it to have a variable resource consumption (Capacity requirements) with fixed duration (Mode), which is not SAP standard so you need a BADI to influence the behaviour and write the rules of populating the resource variable consumption.

Hi Sasibushan, thanks for your reply.. yes I read that link but looks like his issue (multi activity resource because of multiple capacities) is different from mine (multi activity resource with only one capacity but multiple different material orders need to be scheduled)

I have read one of your blogs https://blog.olivehorse.com/multiple-capacity-constraint-modelling-in-ppds and my issue is close to your scenario 2 in this blog. but what I am trying to understand is how did you get 25.649 as variable res consumption when your capacity is 254,850 ? In my case/example what should be my capacity and how do I calculate the value that I need to populate in Rescons(V) field? appreciate your help

Which Badi do we need to use inorder to consider Variable Resource Consumption? We are trying to Schedule Hanger/Drums which has capacity let's say 1000. Multiple Product can be loaded on the Hanger at one time.
