In the original publication by the FDA (which should be NORMATIVE), the rule definition and error message of FDA rule SE2306 conflict with each other.
The rule definition states: "At least one of the these variables or sets of variables should be populated: (DM.RFSTDTC and --DTC) or --STDY, or --VISITDY".
The error message states: "Missing values for all required set(s) of timing variables [DM.RFSTDTC with --DTC] , --DY and VISITDY".
First of all, there is nothing such as a "--VISITDY" variable. May I presume it must be "VISITDY" in the rule definition?
Secondly, the rule speaks about "--STDY" whereas the error message speaks "--DY".
So, what is this rule now about? Is it about --STDY, or is it about --DY?
And when then I look up the rule on the P21 website, the rule is suddenly something completely else:
definition: "At least one of the these variables or sets of variables should be populated: VISITDY, --DY, or --NOMDY"
error message: "Missing values for all required set(s) of timing variables: VISITDY, --DY or --NOMDY".
What has happened here? Are we talking about two rather different versions of the same rule?
