dynamic string concatenation in sql where clause

[tobiasfue]

Is it possible to combine two variables from a select in a subselect?

Example:

select tplnr from table1 as a where ( exists ( select * from table2 where key = @sy-mandt+a~tplnr)).

Focus:

@sy-mandt+a~tplnr

Thanks!

This leads to the following error message: ( is gramatically not allowed here...

Okay.. we are using 7.4 not 7.5... sorry. Thanks!
