ABAP – Validation of manual input

SAPI faced a scenario where I had an ALV grid where all columns were made generic of type (let’s make it simple) CHAR255. Each column has its name in field catalog in format TABNAME-FIELDNAME (+ more human readable column header texts of course). What I needed to achieve was to make validation of data that user entered in the ALV cells. Since the cell validation is not available by default (because of type CHAR255) I had to make it dynamically.
In this article I’d like to share my solution Continue reading

ABAP – ALV custom toolbar button + Import data from clip board

SAPIn this code example I’ll show how to add custom button to your ALV toolbar. This custom button will import data from clipboard into the ALV grid. This can solve issue with classic Ctrl+C and Ctrl+V where there’s a problem that new rows are NOT created in the ALV grid automatically – this will be solved by the extra toolbar button Continue reading

If you need to keep the row selection together with functionality of filter (and others), you can follow my little suggestion Continue reading

ALV – Dynpro controlled by a global class

SAPIn this article I’ll present an approach how to handle a screen with a global ABAP class. The idea is simple – we will create a class which will listen to PAI and PBO events raised by the screen. All data processing and screen element manipulation is done in the class code. Let’s check out how exactly it is done Continue reading

ALV – Keep selection and scroll position after ALV refresh

SAPThere is an issue with ALV grid that if you refresh the grid being in edit mode using method REFRESH_TABLE_DISPLAY (in case you use CL_GUI_ALV_GRID) after you have changed some data, it may happen the cursor and/or scroll goes to the first (top left) cell of the grid. It might be a little confusing for user, but you can avoid this issue by using the following methods (and attached piece of code) Continue reading
