Hi Samantha,

Scrap is calculated based on the Qty to Start figure, rather than the Qty to Complete figure as in your example.

13 (Qty to Start) x .7799 (Yield) = 10.1387 (Qty to Complete).

13 - 10.1387 = 2.8613 (the scrap requirement shown in the MRP Detail Inquiry)

This is correct, as you have processed 13, not 10.

 

Thank you so much

I ahve to admit that I find the terms "scrap" and "yield" very confusing.  As the Scrap Requirement in MRP Demand is based on the parent part number rather than than the components, should it be referred to as "Yield Requirement" rather than the "Scrap Requirement"?  For, isn't yield based on the parent part while scrap is based on the BOM (or components)?

Samantha.  I am actually replying to your posting from a few days ago but for some reason it is not allowing me to post to that one.

So basically you were saying that you could not print a production order.  But in the last sentence you say that the status is R.  That actually means it has been printed.

So what you can do is change the status beack to E.  Do not change it back to F as that would then potentially change the bom if any changes have been made.

You could just take it back to A and leave the allocations but in this case you are risking that the materials are no longer where they were, so changing it back to E keeps the same BOM but will allow the release print to select the material based on current inventory
