SAP IBP FG Production Yield in Heuristic

[berryw1993]

Hello IBP experts.

Is there a way to account for a production yield scrap on finished goods production in the time series heuristic?

For example, if production yield is 5% and consensus demand is 100, I want the heuristic to plan at least 105 for production receipts because the yield demand is 5% of what is needing to be produced.

Thank you,

Hi berryw1993,

I have attempted a similar requirement for one of my clients in both Production Yield level as well as in the component scrap level. To account production yield, kindly follow the below procedure.

1) Create a Custom Attribute(Integer) namely 'ZYIELDPERC'.

2) Add the 'ZYIELDPERC' attribute to Production Source Header MD and integrate the 'Yield %' also at the Production Source Header (say 5) and this attribute to Planning Area and add in the required planning levels.

3) Change the Production Receipt KF to stored/calculated and create a calculation as below

PRODUCTIONRECEIPT@PER-PROD-LOC-SRC = PRODUCTIONRECEIPT@PER-PROD-LOC-SRC(stored) + (PRODUCTIONRECEIPT@PER-PROD-LOC-SRC(stored) * ZYIELDPERC / 100)

4) Also change the request level calculation by changing the reference from stored to calculated.

PRODUCTIONRECEIPT@REQUEST = SUM(PRODUCTIONRECEIPT@PER-PROD-LOC-SRC(calc))

5) After activating the planning area, Run the Heuristics and check the results.

Also let me know if you see a need or implication at Component level.

Thank you, Riyaz! That looks like it does increase the production receipts, however, the component usage, projected stock, etc all use the stored value generated from the heuristic. Did you find any way around this?

Hi Wesley,

Can you confirm whether the request level is mapped to calculated value at Production Receipt KF?

Hello,

You can reduce your 'Output Product Coefficient' equivalent to the Scrap percentage in the Production Source of Header Master Data thus accommodating for the scrap percentage.

Hi Gaurav,

Thank you! That would be one way to do it, but I then lose visibility to how much the demand is increasing due to scrap %. Would be nice to break out the demand streams (consensus demand, production scrap, etc). Not sure if this is possible though?

Hello Wesley,

One way to do it would be to copy the entire dataset plus the Original Output Coefficient ( Without considering scrap ) into another Version and take a Supply Planning Run in the version.
Then you could compare the results with Baseline versions and observe the variances between Demand on FG due to scrap yield.

Thanks

Gaurav

There is no straight forward provision to mention scrap for FG. However scrap percentage can be specified in custom attribute & demand can be inflated using this attribute.

Thank you, Neeraj.

Is there any way to create a new demand key figure to feed the IBP heuristic so you can specifically see consensus demand vs yeild demand, or do I have to add the yeild to consensus demand?
