Hi,
Thank you for the feedback. This is a result of a limitation in the way that that rule is currently performed, which we're aware of and have tagged as something to fix in a future release. As a workaround until that time, you can try replicating line 37 in the config/data/SDTM Metadata 3.1.2.csv file for the additional COVAL+i variables that you have in your dataset, which should prevent that error from incorrectly being produced. We'll be sure to let you know once we've fixed the issue on our end, and sorry for the inconvenience.
Regards,
Tim
The SDTM Implementation guide states in section 5.2.1.1., that COVAL can be extended by additional variable like COVAL1, COVAL2, ... COVAL199 etc., when comment text is too long to fit into the 200 characters of COVAL.
But when doing this, OpenCDISC shows a warning as of a violation of rule SD0058. This rule should be modified to allow for such additional COVAL+i variables in CO.
