Default rule in Order type dependend parameters - OPL8 - Order Settlement

Question

Hello,
We are doing settlement of production orders via Tcode - Ko88.
After execution of the same, system is passing an FI entry to GL - which is mentioned in the Material Master (Valuation Class - 7900) i.e. through OBYC setting.
We have also checked the OPL8 setting (Order Type dependend Parameters - Controlling Tab) in which "Default Rule" is mentioned as - PP1 - Production Material full Settlement.
As the system is passing an entry via "Default Rule - PP1" stored in Order Type Dependend Paramenters:
1. What is the use of Settlement Profile (OKO7) & Allocation Structure (OKO6)?
2. Can we make "Default Rule" field as optional (In Tcode - OPL8) ? since all the settlements are resulting in same Material GL.
Waiting for a positive answer. Points will be assigned definitly.
Thanks & Regards,

Hi,
Settlement Profile:
In the settlement profile, you define a range of control parameters for settlement. You must define the settlement profile before you can enter a settlement rule for a sender.
If you want to settle the costs each time to just one cost center or just one G/L account, you need a settlement profile. As you cannot maintain the settlement parameters during settlement to a receiver, you must save the settlement profile either in the order type or in the model order or reference order.
Allocation Structure:
During settlement, costs incurred under the primary and secondary cost elements by a sender are allocated to one or more receivers. When you settle by cost element, you settle using the appropriate original cost element.
An allocation structure comprises one or several settlement assignments. An assignment shows which costs (origin: cost element groups from debit cost elements) are to be settled to which receiver type (for example, cost center, order, and so on).
You have two alternatives in settlement assignment:
You assign the debit cost element groups to a settlement cost element.
You settle by cost element - that is, the debit cost element is the settlement cost element.
This is a good idea, for example, if the required capital spending for an asset you are building yourself is to be monitored. These costs are settled by cost element to an inventory account in Asset Accounting at the end of the year, or when the measure is complete.
Each allocation structure must fulfil the following criteria:
Completeness
An allocation structure is assigned to each object to be settled. All cost elements in which costs are incurred, must be represented in the appropriate allocation structure.
Uniqueness
Each cost element in which costs are incurred may only appear once in an allocation structure. Only one settlement cost element may be assigned to a source within a particular allocation structure.
Source Structure:
A source structure contains several source assignments, each of which contains the individual cost elements or cost element intervals to be settled using the same distribution rules.
In the settlement rule for the sender you can define one distribution rule, in which you specify the distribution and receivers for the costs for each source assignment.
