Changing parameter type confusion

Former Member — Wed, 18 Jun 2008 20:18:48 GMT

Hi all,

One more question regarding the type of a changing parameter. I want to wrap some FMs in a subroutine. One example is SM02_ADD_MESSAGE. Trouble is I want to include a changing parameter for the message_id parameter. I can't seem to get the type declaration correct. Any pointers?

best regards,

Mat

Declare it as:

MESSAGE_ID LIKE TEMSG-ID

Hi Joy,

I'm still a lil confused on this one. Here is my sample code. I've defined the following subroutine:

FORM add_system_message CHANGING pv_message_id LIKE temsg-id. I call the function module 'SM02_ADD_MESSAGE' in the subroutine and pass pv_message_id as the import parameter.

I call the same subroutine as follows:

PERFORM add_system_message CHANGING gv_message_id.

where gv_message_id is defined as follows:

DATA: gv_message_id LIKE temsg-id.

The program compiles but balks when I run it...seems the parameter has an incompatible type. Am I missing something here?

regards,

Mat

Hi,

U have shown the PERFORM part. But how u defined it in the statement

FROM add_system_message CHANGING gv_message_id LIKE ??????.

...

ENDFORM.

It should also have same type. Check this and get back in case of any issue.

Thanks,

Vinod.

My mistake...the message_id parameter was fine. when i debugged I realized it was another variabel that had the worng type
