SQL - data conversion required (SQL7919)

I have a multirow fetch into a qualified multi occurance DS - code as follows.

I'm getting an SQL7919, data conversion required, on S1ENTDT even
though I defined it 'like' the field I'm fetching.  It's not a hard
error, but I noticed it in my joblog when testing the program in
debug.

any ideas?

d s1DS            ds                  dim(15)      qualified
d S1STYL                              like(FISTYL)
d S1COLR                              like(FICOLR)
d S1LOGO                              like(FILOGO)
d S1CMT1                              like(FICMT1)
d S1CMT2                              like(FICMT2)
d S1ENTDT                             like(FIENTD)
d S1EXPDT                             like(FIEXPD)
d S1USER                              like(FIUSER)
d S1REAS                              like(FIREAS)
d S1STAT                              like(FISTAT)
