scrap qty

[Former Member]

Hi, what is the difference between planing the scrap qty in bom items and through material master (mrp1 for finish products and mrp4 for roh materials and also we can set scrap % for individual bom items)? pls explain any advantages over other?

Hi,

The one maintained in the Material master for FERT is Assembly scrap: if maintained will result in component qty increase.

for example: 10 % assembly scap.

BOM,

FERT A 100 qty

ROH B 50

HALB C 50

After PLanning for A for 100,

the Component qty are

ROH B 55

HALB C 55 ---i.e the Compoenent quantites are calculated on the basis of FERt 110 not 100.

The One maintained in the BOM are Component scarp.

only impacts that compnenet only.

BOM,

FERT A 100 qty

ROH B 50 -- Compoenent scarp--10%

HALB C 50

After PLanning for FERT 100,

ROH B 55

HALB C 50

Yadav,

I hope you are talking about assembly, operation & component scrap.

These are used to calculate the procurement quantity of the components.

If you set assembly scrap in the material master in MRP1, then according to the that % the requirement quanity would be increased for the components which made up the BOM of that material.

As this scrap states, it is assembly scrap. It is maintained in the material master of FG & SFG.

The component scrap given in MRP4 view is meant for that perticular material if it is used as a component in any BOM.

The requirement quantity is increased by that percent.

In BOM you maintain the operation scrap.

It is useful when for any perticular operation scrap comes into picture irrespective of the component.

In aditon to that the net indicator is there in component details in BOM which after setting makes the assembly percentage ineffective for that perticular component.

It is mandotory when the assembly scrap & component scrap are effective for one component.

Hope this clears your idea.
