What is the difference between 'call transaction' and 'submit' in SAP ABAP programming?

When it comes to SAP ABAP programming, 'call transaction' and 'submit' are two commonly used methods for processing transactions. Understanding the difference between these two methods is crucial for ABAP programmers.

Call Transaction:

The 'call transaction' statement is used to call another transaction within the same session. It allows the program to trigger the execution of a specific transaction by simulating user interaction. This method is synchronous and waits for the called transaction to complete before proceeding with the next statement.

Submit:

On the other hand, 'submit' is used to submit a program for execution in the background. It does not trigger the immediate execution of a transaction like 'call transaction' does. Instead, it initiates the asynchronous processing of the submitted program. The program is scheduled to run in the background and the calling program continues executing without waiting for the result.

Overall, the key difference between 'call transaction' and 'submit' in SAP ABAP programming lies in their synchronous (call transaction) vs. asynchronous (submit) execution nature. ABAP programmers need to choose the appropriate method based on the specific requirements of their programming tasks.
