hi all i read this question:
http://sap.ittoolbox.com/groups/technical-functional/sap-dev/clear-rfc-tables-when-using-rfc_read_table-in-a-loop-2614239
but not answer for me.
my question is:
i have a problem:
How to Clear RFC Tables when using RFC_READ_TABLE in a loop
i use the ActiveX Sap components.
FunctDetail : VARIANT ;
SAPFunctions2: TSAPFunctions;
SapFunctions2.Connection:=Connection;
SapFunctions2.Removeall;
FunctDetail := SAPFunctions2.add('RFC_READ_TABLE');
var
i:integer
for i:=0 to 50 do
begin
FunctDetail.exports('QUERY_TABLE').value := 'LFA1';
FunctDetail.Tables.Item('FIELDS').AppendRow.Value( 'FIELDNAME'):='LIFNR';
FunctDetail.Tables.Item('FIELDS').AppendRow.Value( 'FIELDNAME'):='NAME1';
FunctDetail.Tables.Item( 'OPTIONS' ).AppendRow.Value( 'TEXT' ) := 'LIFNR = '''+Ng1.Cellhttp://wc1LIFNR,Ng1.RowCount-1.asstring+'''';
end;
my problem is how to clear the Table Items, the first time work, but in the next loop (when i=1) say a error. SYSTEM_FAILURE and then other error: "No connection to SAP System Available"
i think, for fix the problem, each time clear the Table.Items (or reuse the items) i try for delte the items:
FunctDetail.Tables.Item(1).Delete;
or
FunctDetail.Tables.Item(1).Remove;
also i try:
FunctDetail.Parameter[ 'OPTIONS' ].Value := 'LIFNR = '''+Ng1.Cell[wc1LIFNR,Ng1.RowCount-1].asstring+'''';
but get these error:
"Method 'Parameter' not supported by automation object"
and not work.
Thanks
