def
func:fitsExplain
fitsExplain(recs, spec)
Return grid which explains how data fits the given spec. This function takes one or more recs and returns a grid. For each rec zero or more rows are returned with an error why the rec does not fit the given type. If a rec does fit the type, then zero rows are returned for that record.
If you pass null for the spec, then each record is fit against its declared spec
tag. If a given rec is missing a spec
tag then it is reported an error.
Example:
readAll(vav and hotWaterHeating).fitsExplain(G36ReheatVav)
