Hello, Guys

How to add a new billing strategy?

What are the detailed steps?

for example:
1) write a new class NewBillingTaskBase extends PluggableTask implements NewBillingTask {}
2)
But the question is
1) where's the existing BillingTask?
2) how to make relationship between NewBillingTask interface & view page?

   Hi

   Can you describe your user scenario case study?

   It is not clear what exactly you'd like to achieve.

   Hello

   I'd like to build up a new process for calculating price for each customer in each customized period

   Calculating rules depend on amount of customer usage. For example, when usage amount is less than 100kg the calculating rule differs from calculating rules when usage amount is more than 101kg

   And a input data file contains input data. The input data are in structured format, for example

   customer123 order1 10 customTypeA
   customer456 order2 20 customTypeC

   So, which parts should I add for forming up the whole process?

   How can add a new tab besides the existing ones, which are Customer, Configuration .etc.

   Thanks

   Hello,

   For adding the new tab, I think you need to modify _header.gsp. For pricing changes that you need to make, please check if you can add custom code in a new implementation of InvoiceCompositionTask. This task is called right at the time of invoice generation. So if you need to charge customer specific prices based on quantity, that rule can go into your custom logic when order lines are charged onto invoice as invoice lines. So every invoice line will have new calculation as per the quantity being charged from the order line. This is one option. With this option though you would not be able to see the price charged at the order level. It will reflect directly on the invoice. If you need to see pricing rule applied at order level, as reflect changed price as per the quantity, please let us know and we will suggest another way.

   Thanks,

   Hello,

   Adding a new tab is not so straight-forward, you need a bunch of files to
   change and you may also have to code a controller to handle actions for the
   new tab.

   As far as Pricing solution goes, you need an implementation of IPricing
   interface as a Plugin to make it configurable. This implementation should
   have all the rules according to your requirement.

   If you are on jBilling version 3.x, you can implement drools pricing rules
   and I would recommend that approach because its more modular.

   Hello Technical Support Team

   Yes, we need to see pricing rule applied at order level, as reflect changed price as per the quantity, so what is the another way is ? :)

   Also we need adding rules in invoice generation process, and found there are 4 existing classes implementing InvoiceCompositionTask under

   (1) com.sapienter.jbilling.server.pluggableTask:
       BasicCompositionTask.java
       CalculateDueDate.java

   (2) com.sapienter.jbilling.server.process.task:
       abstract class AbstrackChargeTask extends PluggableTask implements InvoiceCompositionTask {}
       class SureTaxCompositionTask extends PluggableTask implements
   InvoiceCompositionTask {}

   (3) com.sapienter.jbilling.server.process:
       BillingProcessBL.java import InvoiceCompositionTask

   So which class of the above reprents for existing a invoice's total fee calculating rule class?
   Or should we configure classes rules mapping relationships in db? If yes in which table can we configure for control the process?

   note:
   I read the above classes' implementation codes of InvoiceCompositionTask's declared method
   public void apply (NewInvoiceContext invoice, Integer userId) throws TaskException;
    But didn't find java code for calculating total price, so which part of java codes calculates the total price of invoice when invoice is being generated?

   Hello Vikas

   Thank you. What is exact position of IPricing interface? Or should I add a new interface naming IPricing and then add implementation java class? What's the table name in database to be inserted a new record for enabling new added IPricing & implementation java class to work?

   I'm on jbilling 4.1.1-src and how to implement drools pricing rules in detail? For example which java code files should be modified?

   :)

   Thanks,

   Hello Technology Support Team,

   After I added a new class A implemented InvoiceCompositionTask, how can I enable A to take effect and take place of the existing one in order the running logic not still run into the existing logic one?

   Which one is the existing one which is taking effect which are calculating amount in the way price.multiply(quantity)?

   Thanks,

   Hello ,

   For this you ineed to extends class A from PluggableTask.
   (like Class A extends PluggableTask implements InvoiceCompositionTask) . And configure class A as new pluggin. Also you need to add your class A in pluggable_task_type table .

   Thank you
