Choose Development® Programming environment ® Text elements in the ABAP Workbench to branch to text element maintenance. When making a modification, choose the corresponding type of text and choose Change.
For example, you want to change the text elements for a program:
Place the cursor on the line you want to modify. Choose the Change original text pushbutton. The addition of new text elements is also supported in the Modification Assistant.
The procedure for modifying selection texts and list headers is much the same. When changing column headers, be aware that the text can be modified and reset line for line.
In addition to the Change original text function, the functions Display original, Reset to original, and Modification overview are available to you here.
