Howto access TABLES type parameter within function module

CedrikKern — Mon, 24 Nov 2008 11:15:29 GMT

Dear all,

I try to define a callback function for a BAL message with message parameters. It seems to me that the message parameters appended to the message become passed to the callback function as a TABLES function parameter. Thus I tried to define a function module with a TABLES parameter in the function module's interface. This is not possible because this feature seems to be obsolete ( I get a warning: 'TABLES parameters are obsolete! Message no. FL069 Diagnosis...'). I located the position where the function module call is done:

CALL FUNCTION I_S_PARAMS-CALLBACK-USEREXITF
               TABLES
                 I_T_PARAMS            = L_T_SPAR
               EXCEPTIONS
                 OTHERS                = 0.

How can I access the table passed there within my function module?

I already tried to create a changing parameter with the same name and type and a header line in the function module but this does not work for me.

Thanks and kind regards,

...Cedrik

Hi ,

within the exporting parameters use a table type parameter.

create a table type using SE11.

hope this will serve your purpose.

U need to create a TYPE TABLE by SE11 and then create an export or changing parameter based on this table.

So by SE11:

A) Create a structure with all fields included in your varaible L_T_SPAR

B) Create a type table based on the structure above;

C) Use this type in your fm to define the changing or export parameter.

Hi,

thanks for your quick answers I tried what you suggested but this leads to a short dump:

Runtime Errors CALL_FUNCTION_PARM_MISSING Except. CX_SY_DYN_CALL_PARAM_MISSING .... Error analysis An exception occurred that is explained in detail below. The exception, which is assigned to class 'CX_SY_DYN_CALL_PARAM_MISSING', was not caught in procedure "PARAMETERS_SHOW" "(FORM)", nor was it propagated by a RAISING clause. Since the caller of the procedure could not have anticipated that the exception would occur, the current program is terminated. The reason for the exception is: When calling the function module "TPM_TRAC_INC_CALLBACK_READ", one of the parameters needed according to the interface description was not specified. This parameter was "I_T_PARAMS".

The Changing Parameter of my Callback function module is also called I_T_PARAMS and has the same table structure fields as L_T_SPAR.

But i think this can be ignored as its just a warning, you can create a table parameter.

Where is this call?

CALL FUNCTION I_S_PARAMS-CALLBACK-USEREXITF

TABLES

I_T_PARAMS = L_T_SPAR

EXCEPTIONS

OTHERS = 0.

Is it in a std report or custom one?

If the call is a std report u need to create a fm having the same parameter used here, so u need to create a fm with a table parameter like L_T_SPAR although the table parameter is obsolete.

Hi,

if there is no other way but to ignore this warning I will do this.

Thank you for your help and kind regards,
