Error in uploading MD by LSMW for KP26(Activity Prices)

Hi All,

I am stuck with a LSMW issue, I have to upload the Master data for KP26 (Activity prices). I have created recording for this transaction, but when I goes for uploading the data thru data file at the time of processing the batch input session I am getting the error "No batch input data for screen SAPLKPP0 1000"

I checked with the screen but there is no data being uploaded. Can anybody help with this issue. I am stuck with this problem quiet a long time, still it is not getting solved.

regards.
