Change Data Type in Where Condition

Hello Abapers ,

I have an interesting question for masters. Can i change data type in where statement on Eclipse.

For example:

left outer join dd07t on dd07t.valpos = cast( vttk.sttrg as abap.numc( 4 )) and

dd07t.domname = 'STTRG' and

dd07t.ddlanguage = 'T'

Thanks in advance
