CASE WHEN R1.LastExpenseReg = '1900.01.01' THEN 'N/A' ELSE R1.LastExpenseReg END AS LastExpenseReg,

ISNULL(MAX(ESL.DateOfEntry), '1900.01.01') AS LastExpenseReg,
ISNULL(MAX(RH.CreatedDate), '1900.01.01') AS LastPOReg

I guess that some records might have NULL values in TSL.PeriodStart, ESL.DateOfEntry, RH.CreatedDate.

You can do like this:

ISNULL(MAX(ISNULL(TSL.PeriodStart, '1900.01.01')), '1900.01.01') AS LastTimeReg,
ISNULL(MAX(ISNULL(ESL.DateOfEntry, '1900.01.01')), '1900.01.01') AS LastExpenseReg,
ISNULL(MAX(ISNULL(RH.CreatedDate, '1900.01.01')), '1900.01.01') AS LastPOReg
