the fields of an structure

Posted on Feb 23, 2005 at 05:39 PM 12 Views

Sometimes in a function and in an user-exit there are some parameters that are not defined, it appears only the name in the definition parameters, how can i know the fields of the structure without debugging?,

Thanks in advance

    Off the top of my head, I can only think of one function where the "parameter" is not defined. In function GUI_DOWNLOAD, the data_tab parameter under the TABLES has no type associated with it. With this function, the structure of the data_tab takes the structure of the table that you send it.

    Do you have some examples of a IMPORTING or EXPORTING parameters which is not typed? Please post.

    If you look at the code of the function module COPA_UPDATE_STANDARD_MEASURES, you will find that the parameter I_COPA_LINE_ITEM is ultimately used to fill the feild-symbol which is assigned the structure of the table contained in the table parameter I_TABNAME.

    So in other words, here I_COPA_LINE_ITEM should be of the same structure as that of the table you specify in the other parameter I_TABNAME.

    Hope this helps.

      You are absolutely right Rich if you are talking in general terms. But in this specific case, if you give an internal table with any structure other than the structure of the table in the table parameter, it will dump.

      It looks like that when you define your operating concern in COPA and define its structure, systems internally generates several tables and structures. Since each company uses different structure, system has no way of passing the structure information to the function module other than the way it did in this function module.

      But, if this is not the case and the internal table parameter has no structure, you can pass any internal table to it. It will not give you a systax error but it will give you a dump if internally in the code somewhere, it assumes a particular structure.
