I wanted to practice select-options but it gives error at:
SELECT-OPTIONS: kunnr FOR vbak-kunnr.
I tried SELECT-OPTIONS: kunnr FOR kunnr.
But then also it says "Field vbak-kunnr is unknown. It is neither in one of the specified tables nor defined by the 'DATA' statement.
Please tell me the correct way to use statement 'parameters' and 'select-options'.
