Modify Data in create supplier application in MDG

[#1]

Hi Experts,

I have a requirement to enhance standard SAP MDG application by calling a custom FPM on click of a button on Create supplier page to populate some data on a custom FPM. User will select a record from the custom popup and I need to pass data into Name and address field to standard one by overwriting programmatically the one which manually entered.

I need to know how to pass data from custom FPM to standard create customer screen/application. 

Steps

 On click of supplier button I am calling a custom FPM

Custom FPM screen populated

Now I have to select a record from this popup and pass it to standard fields alike name, address, city

You can catch the event when your custom dialog windows closed.  All field values from selected line can be passed as event parameters.  The last step is to write values into MDG BP Feeder Class Genil Layer with BOL statement.
