Hi,
Mean lots of fields have SELECTION as A at table ROOSFIELD then you can make them as visible by using below sample code.
EPORT ZREPORT.
Tables: ROOSFIELD.
SELECT SINGLE * FROM ROOSFIELD WHERE OLTPSOURCE = '<data source name>' AND
OBJVERS = 'A' AND FIELD ='<field name>'.
IF SY-SUBRC = 0.
ROOSFIELD-SELECTION ='P'.
MODIFY ROOSFIELD.
ENDIF.
Above code will work for single field, as per your requirement you can add more fields with help of abaper and make them as visible(SELECTION = P).
Thanks
