BELNR is not required however it is useful. Let us say a customer place an order and as he is not sure he place the order again. Now there are 2 orders you are not sure if there are two IDocs for same order.With BELNR, it has order number of customer system and you can add an optional field with Order Number and incase same order is used it can raise a warning message. You can also use session id to check for duplicate posting if you don’t want to use this.
Usually, in ABAP you use OpenSql statements to retrieve the data. OpenSql statements are similar to normal SQL statements.In case you need to use the function module on a remote system, then you need to use remote function calls like RFC_READ_TABLE. It lets you query data on remote calls as well.
As per my knowledge, SAP PI Messaging Server 7.4 AEX is compatible with JMS 1.02 and JMS 1.1. Using Java Messaging Service, you can connect messaging systems to the Integration Engine.You can refer to SAP Note: 856346 - J2EE JMS AdapterThis note says common FAQ’s about JMS and I have JMS message properties that are of significant. How do I get this data into XI? How do I get this data out of XI?A feature generically referred to as XI adapter-specific message properties was introduced in the adapter framework. This allowed additional adapter information to be attached to a XI ... Read More
Try using Table EUFUNC or also check Function Module: RS_TESTDATA_GET. When you save test data in SE37 it's going to be saved in test data directory.
It is not possible to retrieve files using BAPI from SAP system. There should be a way to copy the file to a shared location and you can read the file from there using .NET.
Java 8 introduces a new concept of default method implementation in interfaces. This capability is added for backward compatibility so that old interfaces can be used to leverage the lambda expression capability of Java 8. For example, ‘List’ or ‘Collection’ interfaces do not have ‘foreach’ method declaration. Thus, adding such method will simply break the collection framework implementations. Java 8 introduces default method so that List/Collection interface can have a default implementation of foreach method, and the class implementing these interfaces need not implement the same. Syntax public interface vehicle { default void print() { ... Read More
As per my understanding, it is not feasible. You can access local class dynamically but statically referring to it in another class seems impossible. You might think about calling methods as dynamic in this case.
Constructors are similar to methods but, They do not have any return type. The name of the constructor is same as the name of the class. Every class has a constructor. If we do not explicitly write a constructor for a class, the Java compiler builds a default constructor for that class. Each time a new object is created, at least one constructor will be invoked. A class can have more than one constructor. this() and super() are used to call constructors explicitly. Where, using this() you can call the current class’s constructor and using super() you can ...

The best possible solution to avoid this issue is by adding breakpoints to the best places. This issue is common with VBA and C# while debugging code includes COM libraries.
The full form of API is Application Programming Interface. It is a document which gives you the list of all the packages, classes, and interfaces, along with their fields and methods.Using these API’s, the programmer can know how to use the methods, fields, classes, interfaces provided by Java libraries.
