SVSTDY variable value is imputed

Hi,

I am getting an error:SVSTDY variable value is imputed. In the details tab in pinnacle report under column B it stated Null value of RFSTDTC, but in the dataset it does not have missing value. This error is generating mainly because RFSTDTC and SVSTDTC are exactly same and due to mathematical operation +1 has been added as there is no day 0.

Please suggest how to handle this.

Thanks,

Abdul

Hi Abdul, …

Hi Abdul,

There is another check SD1090 for incorrect calculation of Study Days. Its algorithm is the same as your described. So, I assume that you have SD1089 validation messages due to different reasons like inconsistency in USUBJID values in SV and DM domains. Be aware that any non-visible characters like space " " still represent an actual value in variables.
