i have written.i don't know why it is not working.any help
would be greately appreciated.

did you check database it is a relational table.Materialrequistionorder with materialrequistiondetail both
table have common field requistion no how should i check both table
at the same time.

MsgBox("requistion no is already exists")

That line of code shouldn't work, period.
You should leave out the parenthesis.

MsgBox "Requisition number already exists", vbInformation, "Requisition Status"

Or

dim intMessage as integer

intMessage = MsgBox("Requisition number already exists.")

Other than that, if you could put a break point at that line and post what the values from ReqNo.Text = rsDetail.Fields("requistion_no") yield, that would be helpful in debugging this.

i got err.description in immediate window.Item cannot be found in the collection corresponding to the requested name or ordinal.

Strait from your DB...

SELECT MaterialRequisitionDetail.*, MaterialRequisitionOrder.*
FROM MaterialRequisitionOrder INNER JOIN MaterialRequisitionDetail ON MaterialRequisitionOrder.requsition_no = MaterialRequisitionDetail.requsition_no;

Execute your testing rs and if it fails an if statement like in the earlier post then the records do not exist. However the if statement above will also tell you if it exists.

Good Luck

Item cannot be found in the collection corresponding to the requested name or ordinal.

Please, be specific. What item?
if while in the Immediate Window you try this, then

?rsDetail.Fields("requistion_no")

you should see the value of the field. If not, then you may have the name spelled wrong. Check your recordset field names, to see if the field you're looking for actually exists as you have it spelled.

Also put a break at this line, hit F8 to advance one line and see in the Immediate Window if you can pull up any values: rsOrder.Open sqlQueryOrder, con, adOpenDynamic, adLockOptimistic

' Immediate Window
?rsOrder.Fields.Count

Should tell you if your open statement worked by showing you that there actually exist fields in your recordset. You can then

MoveNext
?rsOrder.Fields("SomeFieldName")

in the immediate window to see if you're actually getting your data.
