Credit Management: Difference Between Static and Dynamic Credit Check

Question

Hi,
Could anyone tell the difference Between Static and Dynamic Credit Check?
According to website: http://www.sap-basis-abap.com/sd/difference-between-static-and-dynamic-credit-check.htm ... this is the answer:
====================
Simple Credit Check : Tr.Code - FD32
It Considers the Doc.Value + Open Items.
Doc.Value : Sales Order Has been saved but not delivered
Open Item : Sales Order has been saved , Delivered, Billed & Transfered to FI, but not received the payment from the customer.
Static Credit Check it checks all these doc value & check with the credit limit
1) Open Doc.Value / Sales Order Value : Which is save but not delievered
2) Open Delivery Doc.Value : Which is delivered but not billed
3) Open Billing Doc.Value : Which is billed but not posted to FI
4) Open Item : Which is transfered to FI but not received from the customer.
Dynamic Credit Check         1) Open Doc
                                            2) Open Delivery
                                            3) Open Billing
                                            4) Open Items
                                            5) Horizon Period = Eg.3Months
Here the System will not consider the above 1, 2, 3 & 4 values for the lost 3 months.    
====================

Answer 1

Hi Tanish,
Diff between Static and Dynamic Filters.
Example One at report Level.
Create a variable for a Infoobject say ,Material .
1)In the Query Designer and if u restrict it to some 10 materials at query level, the report will display for only those 10 materials only.This is Static Filter.UR AHrdcoding it to those materials.You cant change them at Query Run time.i.e not changeable by user.
2)If u give the variable as input ,and when u run the query ,u can can choose the material,may 10 may be 1 or may 20 .It is dynamic.Changeable by user at run time
Example Two at DTP and Start Routine Level,say Document Type.
1)If u give filters in Start routine it is Static as u cannot change it in Production,not changeable by user.
2)f u give filters in DTP it is Dyanamic as u can change it in Production.U can give any doc type,Changeable by user at run time.
Hope it is Understood.
