mismatch in usubjid was not highlighted as missing usubjid in DM domain

in one of our study the usubjids only has numeric value i.e 111111.3777710 and in DM this usubjid value was fine but in pp domain for some issue related to csv to sas dataset conversion the last 0 got truncated so the usubjid in pp was 111111.377771, clearly this subject is not the same as in DM but this issue was not highlighted in opencdisc check, we were expecting a error with code FDAC040 i.e subject not present in DM domain. but this did not happen.

could this be a bug in opencdisc? please could you confirm.

we are expecting more studies in the future with such usubjids that have no character part in it.
