Mapping: How to convert Blue color suppress to gray color suppres

Dear All.

my scenario is JDBC to SFTP scenario.

so from JDBC end i'll get all the field, and i need to place the condition whenever the value come i need to generated the target segment/fields.and i need to avoid the file which come constant value  of "END"as well.

but when i do mapping , i'm getting all blue color suppress because no value at source side. because of blue color suppress value is not populating at target segment, please advise how i can get the gray color suppress in this case.  or some other way do we achieve?

fyr
