Code for Payment Method Drop Down in ESS Banks Detail

Question

Hello ,
I am on EP7.0 ERP05 NW04s and trying to modify the Payment Method DropDownByKey on the Banks Detail screen....I want to know where's the code which is filling the dropdown for the corresponding values of Payment Method like Direct Deposit for 'D' stored in R/3 for Zlsch field....
And then I want to filter the DropDown to list only Direct Deposit and Payroll Check......
Any help would be highly appreciated.

Hi All,
I have done the WD changes like this:
Bank Iview:
Changes done to restrict the payment method combo box.
1.Crete the simple type(PaymentMethod - Ennumeration) with values that you wanna populate(get these values and corresponding text from Back-end)
2.Create a context variable (PymtMethodFromSympleType) and attach it to the simple type PaymentMethod.
3.Attacht the PaymentMethod drop down box to context variable (PymtMethodFromSympleType).
Coding:
4.In wdDoModify()
Assign the actual payment method that is coming from back-end(Idefault value in case of new back and existing value in case of Edit) to context variable that is attached to paymentmethod drop down.
wdContext.currentContextElement().setPymtMethodFromSimpleType(wdContext.currentSelectedInfotypeElement().getZlsch());
5.Create an action for drop down box (Action PaymentMethodChange) which creates the method onActionPaymentMethodChange()
In onActionPaymentMethodChange() method Assign the vlaue of the created context element to actual back-end context variable.
wdContext.currentSelectedInfotypeElement().setZlsch(wdContext.currentContextElement().getPymtMethodFromSimpleType());
I did the testing for all scenarios in portal and it works, but I might have to check with AP as well to see it doesn't bounce at their end.
Let me know if you have any questions,
Thanks,
Hari.
