Hi,

STEP LOOPS

Step Loops are type of screen table . Step loops are repeated blocks of field in a screen. Each block contains one or more fields and these blocks are repeated. Step loops aren’t like actual table. You can scroll vertically but not horizontally. Three steps are associated with creation of step loops:

• Creation of step loops on screen, which includes declaring fields on the screen and then defining the step, loops for these fields.

• Passing data to the step loop is exactly similar to the passing of data to table controls.

• In step loop, you don’t need to define the step loop as such in the module pool program but the cursor needs to be defined in the program.

Types of Step Loops

• Static – Static Step Loop (SSL) have fixed size that cannot be changed during the runtime. If user resizes the window, the size of the static step loop is not changed.

• Dynamic – Dynamic Step Loop (DSL) is variable in size. When the user resizes the window, the system increases or decreases the number of the step loop blocks.

You can have only one dynamic step loop and can have as many static loops in your transaction.

Programming with the Static and dynamic step loop is exactly same. For the system or for the user it doesn’t make any difference whether it is static or dynamic step loop. Only attribute, which you fix during designing of the step loop, is type attribute for step loop F for fixed i.e static and V for variable i.e. dynamic.

Writing code for Step Loop in the flow logic.

PBO.

Loop at itab cursor cl.

Module set.

Endloop.

PAI.

Loop at itab.

Endloop.

Empty loop is must for both table control and step loop

LOOP AT statement for step loops and Table controls is similar. Loop At statement transfers the data to screen table. You need to have the Module to assign the values for the screen table.

In module pool program you need to define the cursor.

Date: CL TYPE i.

Cursor parameter tells which line of step loop display should start.

“Module Set” in module pool program assigns the values to step loop fields, which is similar to table controls.

Refer to this program DEMO_DYNPRO_STEP_LOOP

Table controls:

Used to display multiple records, with vertical and horizontal scroll bars and the facility for selecting the records.

hi kumar

the difference is as follows

Some of added features of Table Controls over Step Loops:

Scroll through the table vertically and horizontally

Re-size the width of a column

Scroll within a field (when field contents are wider than the field)

Select table rows or columns

Re-order the sequence of columns

Make selective columns editable

Save the current display settings for future use

Handled locally by your Systems SAP GUI Frontend – Minimal programming

needed.

Displaying large amounts of data in a table

Can be configured by the user

Allows you to change several lines of a table at the same time

It is processed using a loop

The top line is the header line. One line can have up to 255 columns.

PAI is triggered when you scroll vertically or save the settings

Table controls have both horizontal and vertical scrollers and cursor control logic is designed implicitly.

Step loops have only horizontal scrollers and cursor control logic is to be designed by the user explicitly.
