I have a itab with all fields and descriptions of a database-table. Now i want to generate a selection screen dynamically. I want to create a select-option for every field of the table.
First I read all fields of a database table into my intern table:
CALL FUNCTION 'DDIF_FIELDINFO_GET'
tabname = 'database_tabname'
dfies_tab = it_tabname_fields.
Then I tried to generate a dynamic selection-screen with a select-options statement per field of the itab, but it doesn't work:
SELECTION-SCREEN BEGIN OF BLOCK b1 WITH FRAME TITLE text-001 NO INTERVALS.
LOOP AT it_tabname_fields INTO s_tabname_fields. "should be 14 loops and 14 lines
SELECTION-SCREEN BEGIN OF LINE.
SELECTION-SCREEN COMMENT (25) s_tabname_fields-SCRTEXT_S FOR FIELD var1. "the name of the field should be set dynamically from the itab
SELECT-OPTIONS var1 FOR tabname-s_tabname_fields-fieldname. "s_tabname_fields-fieldname should be set dynamically for each line
SELECTION-SCREEN END OF LINE.
SELECTION-SCREEN END OF BLOCK b2.
I know that this doesn't work but it should help you to understand what i want to do. It doesn't create more than one select-option (it should be 14 because there are 14 lines in the table) and it doesn't get the values from the table.
I hope you can help me...
