VENDOR MASTER DISPLAY REPORT (Z)

Question

this report displays the vendor master record and used LDB KDF. Can anyone clarify this :
Is it the LDB program that fires the GET EVENT to my program ? Does it selects the data based on the selection (dynamic scree) and fires this event and if it does not get any data , it doesnt fire the event ??
In our program , when we write a get statement : does it get one record at a time ( out of the selected records ) from the ldb ?
Do we need to do special append or move in our program to get that data into the program for further use ???
I have this code for this report that uses the LDB KDF !! When i give in the selection screen (dynamic) say country US , and write a get lfa1 at start-of-selection , it works good and gets the data ...but if i want to do selection based on Conpany code ....and wrote a GET LFB1 statement , it doesnt work ?? I m pretty messed up in this ...so writing this long q...would look for help ..
get lfa1.

Answer 1

Make the fields suppress during display. Configure it in SPRO>Financial Accounting (New)>Vendor Accounts or Customer Accounts>Master Data>Preparations for Creating  Master Data>Define Screen Layout per Activity (Vendors) (Customers)
Change the field status for Display in all areas (General, Company, Sales/Purchasing) for the following under the General Data > Payment Transactions> Bank Details. Make it Suppress.
