    Thanks all. Here is the SSIS expression for those who only need to use SSIS,

    DATEADD("hh",17,(DT_DBTIMESTAMP) ( (DT_STR,30,1252) (DT_DBDATE) (DATEADD("dd", -1 - (DATEPART("dw", getdate()) % 7), getdate()) ) ) )

    If I run this now, I get this:

    15/06/2019 17:00:00

    which, of course, is Saturday. Are you sure that it's working for you?

    My recommendation would be to rewrite it so that it does not use the "DW" DATEPART so that it's agnostic to DATEFIRST and other settings.

    RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
    First step towards the paradigm shift of writing Set Based code:
    ________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

    Change is inevitable... Change for the better is not.
