Flow Diagram of the DO Loop

Before we explore examples, let’s visualize the flow of the DO loop:

Explanation of Flow Diagram of Do loop

1. Start: The loop begins execution.
2. Code Execution: The block of code within the DO loop is executed.
3. Condition Check: After code execution, the loop checks a specified condition.
4. Continue or Exit: If the condition is true, the loop returns to step 2 for another iteration. If false, the loop exits, and program control moves to the next statement after ENDDO.

Now, let’s dive into practical examples to illustrate the usage of the DO loop.

DO loop in SAP ABAP is an unconditional loop that executes a block of code several times without providing a specific condition. It is a fundamental construct that facilitates the iterative execution of a code block until a specified condition is met. Programmers, through the incorporation of do loops, can automate processes; manipulate data, and control program flow based on dynamic conditions. In this article, we’ll delve into the syntax, flow diagram, and practical examples of the DO loop in SAP ABAP.
