功能模块 RSAQ_REMOTE_QUERY_CALL 选择参数

Question

I'm trying to use function module RSAQ_REMOTE_QUERY_CALL via the rfc call (.NET Connector 3) but I have a problem with selection parameters. My query has two parameters:

• Material (SP$00001)
• Language Key (SP$00002)

I would like to provide them from my C# program and don't want to use variant at all. When I use variant - the query works just fine, but with parameters, I always get NO_DATA_SELECTED exception. I append parameters like this:

        var selection = query.GetTable("SELECTION_TABLE");

        selection.Append();

        selection.SetValue("SELNAME", "SP$00001");
        selection.SetValue("KIND", "S");
        selection.SetValue("OPTION", "EQ");
        selection.SetValue("SIGN", "I");
        selection.SetValue("LOW", "Material");

        selection.Append();

        selection.SetValue("SELNAME", "SP$00002");
        selection.SetValue("KIND", "S");
        selection.SetValue("OPTION", "EQ");
        selection.SetValue("SIGN", "I");
        selection.SetValue("LOW", "EN");

Is this possible to use selection parameters with this function module?

Answer 1

Two things that might help:

• Ensure that you set KIND to S for select-options only - for parameters, it has to be P . Use the function module RSAQ_REMOTE_QUERY_FIELDLIST to find out the types (and names as well).
• Try using the internal, single-character language E instead of the external language EN .
