It is important to note that whichever attributes we assign to the first group are replicated to the entire step loop. You can increase the number of records at abwp.
Sample Specs What’s Hot? This article throws light on the concept of Step-loops in Module screen programming. How to design Step-loops? Fixed Step-loops Incase of Fixed step-loops, the number of lines of records module pool programming in abap step by step pdf download be fixed as when designed. A step loop is defined in the screen painter transaction SE51; these are unlike the table control elements which can be spread over multiple lines and can be combined into one group which would be repeated within the step loop.
Enter name and email address below:. For fixed step loops the number of repetition groups has to be predefined. Use information on this site at your own risk.
Incase of Fixed step-loops, the number of lines of records would be fixed as when designed. Variable Step-loops In case of variable step-loops, at runtime we can increase the number of repetitive blocks depending on the size of the screen.
01 – ABAP Tutorials
As described, we would first place the input-output fields and text-fields as per the number of columns to be displayed as shown below: Click here to continue.
We will look into a requirement where we have display records in a step-loop on screen in such a manner that we will keep the step-loop fixed to 5 rows for simplicity and based on the number of records; the records will flow onto downllad next screens. Also moudle there are only 2 records to be displayed then only 2 rows will appear on the screen with no buttons for navigation.
Step-loops are a very old concept and their use has been drastically reduced after moduls onset of Table control. Step-loops are actually the predecessors to Table Control concepts and from programming point of view they are quite similar.
Step-loops in Module Pool Programming. Graphic Design by Round the Bend Wizards. The vertical size of variable step loops changes if the user changes the vertical size of the window.
Step loops are objects for screen table display that are added to a screen in the Screen Painter. They are preferred in cases of Radio-frequency applications where ALV displays or table controls pose a hindrance with respect to small displays and navigational issues. For every module pool programming in abap step by step pdf download, any number of fixed step loops can be defined but only one variable step loop. Every vertical size change triggers PAI if a variable step loop is defined on the screen.
Every effort is made to ensure content integrity. Requirement to be designed We will look into a requirement where we have display records in a step-loop on screen in such a manner that we will keep the step-loop fixed to 5 rows for simplicity and based on the number of records; the records will flow onto the next screens.
In case of variable step-loops, at runtime we can increase the number of repetitive blocks depending on the size of the screen.
step by step procedure in module pool..programming
The pre-requisite to understanding and design of step-loops is to have a fair idea over module pool programming. But in certain applications such as Radio Frequency there is no other alternative than using step-loops.
All product names are trademarks of their respective companies. Step-loops are of 2 types: Introduction to Step Loops This article throws light on the concept of Step-loops in Module screen programming.
Although the number of records can be decreased as per programming logic if number of records in table to be displayed are less than fixed number.
