Parallel operations in IBP S&OP TS Based Heuristics

[abasu07]

Hello Experts,
There is a requirement to produce the FG through multiple operations in multiple resources.
For example, if there is a demand of 1000 & there are 4 separate Resources to be used to produce the required quantity. In those 4 resources, dependent demand for each Resource should be 1000 each.
At the end of the week, the final receipts should be 1000 for the FG.
This should be achieved through TS based S&OP Heuristics. 
Please suggest the best approach to achieve this scenario,

Hi,

there a no parallel operations in time-series based planning. But for your use-case you can assign the 4 resources to one production resource.

See also Production Source Resource and the first note there:
"If you assign more than one resource to a production source of supply, the consumption of these resources isn’t split. All of them are consumed as if there was only one resource. Assigning multiple resources to one source means that all the resources are consumed according to their respective consumption rates, that is, if one of the resources doesn’t have enough capacity, the source can’t be used."

Hi Carsten,
Thank you for the answer.
Just to be clear : the requirement is if there are 4 different operations to be performed one after the other in sequence
Operation 1 -> Operation 2 -> Operation 3 -> Operation 4 
Each operation takes 1 week. So , if the demand is 1000 in Week 8, then each operation should be scheduled one week prior to each other.
Operation 1 done in Week 4; Operation 2 in Week 5; Operation 3 done in Week 6; Operation 4 done in Week 7. 
So final available receipts at end of Week 8 for the FG = 1000.
Attaching snapshot for your reference.
Can you please suggest if this can be achieved in Time series based supply planning.

Hi,
your scenario should work with a production source that has a lead time of 4 weeks and resource consumptions with according Capacity Consumption Offsets.
See Production Lead Time, section Capacity Consumption Offsets for more information.

Hi Carsten,
Thank you for the response.
While using Capacity Consumption Offsets, we need to use PCAPACONSSTART & PCAPACONSEND attributes.
With these 2 attributes, we will be able to toggle the start & end of the operations within the PLEADTIME.
But, how can we define the sequence of the operations? Operation 1 -> Operation 3 -> Operation 2 -> Operation 4.
If we have the PLEADTIME = 4 weeks, Operations 1 should start 1st followed by Operation 3 (2nd), then Operation 2 (3rd), lastly Operation 4 (4th).

For the sequence Operation 1 -> Operation 3 -> Operation 2 -> Operation 4 you would set:
For resource 1 / operation 1: PCAPACONSSTART = PCAPACONSEND = 0
For resource 2 / operation 3: PCAPACONSSTART = PCAPACONSEND = 1
For resource 3 / operation 2: PCAPACONSSTART = PCAPACONSEND = 2
For resource 4 / operation 4: PCAPACONSSTART = PCAPACONSEND = 3

The operations are only implictly defined via the PCAPACONSSTART/END offsets. If you need additonally other operation sequences you'd have to define additional production sources. Are there any other restrictions/requirements on the operations? If yes, it'll be probably hard/impossible to model this is TSBP.
