      While copying data from RecData85 to RecData85Hist and while copying RecData942 to RecData942Hist. this error is coming. after this error is not coming contiguously. but when coming this error data is not getting copied to other historic table.

      I am not understanding why its coming now after 3 yrs. We have not seen this error before on our PROD server.
