We use SYS(2015) and I can't recall ever having a problem with it. For example

SELECT SYS(2015) AS uid,* FROM sometable INTO CURSOR somecursor


SELECT SPACE(10) AS uid,* FROM sometable INTO CURSOR somecursor
REPLACE ALL uid WITH SYS(2015)

In both cases

SELECT COUNT(DISTINCT uid) FROM somecursor

shows RECCOUNT('somecursor') regardless of how many records were created
