Assembly, component + operation scrap

Question

Dear All,
[I raised this issue on MM board and I was advised to come here. Maybe you can help me.]
I haven't got experience in SAP, that's why I'd like to ask for your help in this issue.
Could you highlight/explain how these work?
(effects on MRP run + behaviour when booking against PrdOrd; e.g. when I book against PrdOrd what will be the movement types?)
thx

Hi,
  Assembly scrap:
              Assembly scrap takes into account all the faults that occur when the
              components are put into assembly.
              The system automatically increases the qty to be produced by the
               percentage of scrap.
               can be maintained in MRP 1 View as a percentage
              Reqd qty   100 pcs
              Assembly scrap 10 %
              After taking scrap reqd qty is 110 pcs
   Component scrap:
              Component scrap takes into account all the faults that occur before the
              components are built into assembly.
              Can be maintened in MRP 4 view if the scrap is going to be for all boms
              can also be maintened in BOM item detail screen if the scrap is for
              particular Bom .
              Reqd qty 100 pcs
              Assembly scrap 10%
              component scrap 10 %
              Reqd qty            121 pcs of components
Operation scrap :
             Befor high value components are built into assembly the system carries
             quality control check for the assembly.Faulty materials that were taken into account in assembly scrap aren ot passed on to the next operation and hence they are removed.
            Maintain the operation scrap in the BOM item details screen under general data /qty data.
           Qty to be produced 1000 pcs
            Assembly scrap     10 %
  component scrap  no entry
  net indicator not set
  scrap qty 100 pcs
           qty to be produced 1000 pcs
           Assembly scrap     10 %
           operation scrap 1 %
           net indicator set
            scrap qty              10pcs.
