What is step-loop? Explain all the steps?
Ans A step loop is a repeated series of field-blocks in a screen. Each block can contain one or more fields, and can extend over more than one line on the screen. Step loops as structures in a screen do not have individual names. The screen can contain more than one step-loop, but if so, you must program the LOOP…ENDLOOPs in the flow logic accordingly. The ordering of the LOOP…ENDLOOPs must exactly parallel the order of the step loops in the screen. The ordering tells the system which loop processing to apply to which loop. Step loops in a screen are ordered primarily by screen row, and secondarily by screen column. Transaction TZ61 (development class SDWA) implements a step loop version of the table you saw in transaction TZ60. Static and Dynamic Step Loops Step loops fall into two classes: static and dynamic. Static step loops have a fixed size that cannot be changed at runtime. Dynamic step loops are variable in size.
