Table parameter in FM

Former Member — Tue, 16 Dec 2008 15:57:29 GMT

Hi,

i would like to create a function module that takes a list of messages(BAL_S_MSG) and a log object (BAL_S_LOG) (basically it will be used to add log messages in different programs)

I can't put directly the type BAL_S_MSG in the table definition tab because it is not defined as a table.

Do i have to create a table with the same structure as BAL_S_MSG or is there some other trick i could do ?

Thanks a lot.

Tom

Just create a table type with the structure 'BAL_S_MSG' and use that. You should also use the importing or exporting parameters instead of the tables parameter. Just do:

IMPORTING

X_parameter TYPE your_table_type

EXPORTING

y_parameter TYPE your_table_type

This will create an import or export table.

Hope that helps,

Michael

Or just use an existing table type which uses structure BAL_S_MSG (e.g. BAL_T_MSG).

BAL_S_MSG is defined as a structure so you should be able to use it in the FM 'tables' tab as 'TYPE'.

How are you adding it? What error message are you getting?

Use BAL_T_MSG instead of BAL_S_MSG

I'm getting : "Only table types may be used as the reference type for a table parameter"

Hi,

You no need to declare the table in the database same like BAL_S_MSG structure. If you have this structure in the database or you can create the structure using SE11.

Different ways of declaring the table in FM.

1. Exporting Tab - need to refer to table type for all the parameters delcared in this tab ..which will behave as table in the FM.

2. Tanle Tab - need to refer to structure type for all the parameters delcared in this tab ..which will behave as table in the FM.
