Standard cost estimate - cost relevancy / best practice

Hi Experts,

could any of You pls help me how to add a set up scrap figure to a BOM - partially relevant to calculation.

The scenario is the follows: I would like to add a fixed amount of a component to each production order - used during machine set up. This amount should not depend on order qty but fixed for each prd order. So I added a fixed amount into BOM - which is ok for prd planning and procurement point of view - but not for calculation.

The standard calculation is for lot size 1000 pcs - but the fixed setup scrap is for different qty prd orders - ex. if average order qty is 5000 pcs, and the set up scrap is 5kgs - only 1 kg or 20% should be relevant for 1000 pcs calculaiton lot size.

I have tried to set calculation relevancy code in BOM item - stpo-sanka as 20% relevant. But this indicator works for standard cost estimate (ck11n) - as 100% or no relevant for costing - but no partial or percentage. I found no good user exit to activate.

Could any of You pls advice me how to handle this situation - when fixed qty required for production planning but partial qty (value) for calculation.

Answers will be appreciared.

      Normally, costing lot size should equal the average production lot size. In your particular case, you should set the costing lot size = 5,000.

      Of course if you run into smaller quantity, the variance is negative effect since your setup cost / piece will be higher. True for vice versa. This allows you to monitor the efficiency of planning or order taking.

      Hope it helps.
