There are many ways to do this, and they depend on the conditions of your scenario.

Is the class on the server or on the client?

If it is on the client, you will be OK with just creating parm methods in the class for each of the data fields you want to pass over:

parmCustomerAccount(), parmSalesOrder(), parmItem(), etc.

and in the clicked method overridden on the button, create a new instance of your class and invoke each of these methods in turn, passing in the corresponding data.

If the class is on the server, it's a bit more tricky, as you'll also want to avoid multiple RPC calls, so you'd want to pack the data before it is being passed, which depends on the types of data you are passing - if they are simple value types, easy, just use a container, if however you have records in there as well, it will depend.

Alternatively, depending on the number and types of fields you need to pass to the class, you can use the Args() class and have the button be an actual menuItemButton.

Some examples of this here:

So describe your scenario a bit better, if the above does not help.

Thank you, Vanya.

Scenario:

Will be created to review all invoiced sales order lines and gather data from the ended production order. The gathered data will be written to a new transaction table. The new transaction table will be the source of the data generated by this report. The fields stored will be: Plant, Customer Account, Process, Operation, Order Number, Invoice Number, Invoice, Date, Article (Item), Quantity, Weight, Sales Line Amount, Value by Line, Value by Weight.

A standard report dialog will be generated and presented to the user for input. After the user’s input is captured, the new transaction table will be queried and the data presented in a simple grid based form with the raw data that can then be exported for further analysis and formatting.

Go with my first suggestion for now, where you have individual methods for the various data.

Let us know when you succeed.

If your button is a menuItem then you can access the caller form data source

in menuitem buttons specify the datasource property as forms datasource name

using following method

args.caller().record();

you can write this statement main method

Please verify if this helps you solve your requirement
