I have created a screen in ABAP for a new Infotype. Inside the program, I'm doing a loop screen to get different values, but the most important is to know the value of the field inside of the value of screen-name.
An example
screen-name = 'table-field'
valuefield = screen-name.
**if valuefield is initial.
...
endif.**
How can I do this?
You can dynamically access a screen value by using FIELD-SYMBOLS
screen-name = 'table-field'.
assign (screen-name) to FIELD-SYMBOL(<fs>).
" you must check if the assignement has been done successfully
" before accessing the content
if sy-subrc = 0 and <fs> is initial.
endif.
If your ABAP version does not allow inline declaration you can consider this:
screen-name = 'table-field'.
FIELD-SYMBOLS <fs> type any.
assign (screen-name) to <fs>.
if sy-subrc = 0 and <fs> is initial.
endif.
