Creation of Routing

Question

Hi All
       In my current scenario am having a Roll of 1.2m width, this roll is slit down to 2-3 different sized child rolls along the length with different widths like 0.5m, 0.3m & 0.4m (1.2=0.50.30.4). These child rolls are used are treated as SFs & from each roll FGs are cut along the length of each child roll; from each child roll(SF) a sprecific FG is taken out. The flow of requirement flows as given:
Requirement of FG gives rise to requirement of Child Roll(SF) which further gives rise to requirement of mother roll(ROH). 
My problem is that when am having requirement of 0.5m width child roll I would slit the mother roll and with that am having other child rolls as well for which currently am not having any requirement, but later on other child roll's requirement would be there, am unable to understand how to make routing for these child rolls & how to make BOM of the same.
Waiting for your valuable inputs.

Hi,
As per your requirement, FG is Make to order scenario.Strategy 20. So sales order triggers the production.
When MRP run, dependent requirement will create.In this SFG 0.5m roll consider Make to order scenario. It will trigger the requirement of Mother roll.
Consider 0.4,0.3 Make to stock scenario.Use Strategy 10 in mrp 3 view.
BOM for FG:
Header - FG 0.5 Roll, qty 1 roll
Item - SFG 0.5 roll , base qty 1 roll.
BOM for SFG:    Header - SFG 0.5 Roll, qty 1 roll
                           Item  0010 - Mother roll , base qty 1 roll.
                                   0020 - SFG 0.4 roll, base qty -1 roll (co-product)
                                    0030 - SFG 0.3 roll, base qty -1 roll ( co-product)
Routing for FG: Create as normal routing with component assignment 0.5 roll.
Routing for SFG: Create as normal routing with component assignment Mother roll.
Process: When sale order comes system create dependent req for SFG 0.5 roll and also below level ie, mother roll against sales order.
Do GR for mother roll against P.O by MIGO.
While processing SFG (0.5) production order  0.4,0.3 co-product will produce.
Do GR for all SFG 0.5, 0.4, 0.3 roll.To produce FG 0.5 roll issue SFG 0.5 roll .
When requirement comes for other FG of 0.4, 0.3 roll, issue these SFG which you produced from mother roll.
System will show you the error message, because these stocks are assigned to sales order of FG 0.5 roll.
So make MB1B 411 E mvt. Now sales order stock convert to unrestricted stock.Issue the SFG. Do GR for FG 0.4 roll.Remaining as like as regular process.
Note: Create BOM for FG 0.4 roll & FG 0.3 roll with item of SFG 0.4 roll, SFG 0.3 roll respectively.
