Actually this is a fairly generic exception. CX_SY_NO_HANDLER is raised when there has been a system exception but there is nothing registered to handle it. This is sort of a catch all for exceptions. You might want a try ... catch around your method call and at least catch this exception. You then might be able to receive more details about what exception is being thrown.

i found out that the message doesn occur because i passed an internal table 'WITH HEADER LINE' to the method.

does this mean that passing an internal table defined 'with header line' is generally forbidden within the OO context???

Tables with header lines are not allowed in OO. However a quick fix is to just pass your table without the header line. Just use '[]' on the end of the table name in the method call.

call method class->method


my_table = local_table_with_header[].

Hello Tobias,

in ABAP Objects You should allways define typed data:

In your special case:

data: lt_itab type standard table of xxx_type ...

data: lt_itab type hashed table of xxx_type ...

data: lt_itab type sorted table of xxx_type ...

data: lt_itab type any table ...

Don't use the occurs statement anymore.

You will find a sample definition in the report I have sent You.
