Conditional Result based on Dates

Hi, GMadd 

Based on your description, I have created many measures to achieve the effect you are looking for. Following picture shows the effect of the display.

Measure:

Status1 =

VAR _getCreateDate =

    SELECTEDVALUE ( 'Table'[Created On] )

VAR _getPlanedDate =

    SELECTEDVALUE ( 'Table'[Planned Goods Issue] )

VAR _getShippedDate =

    SELECTEDVALUE ( 'Table'[Shipped Date] )

RETURN

    SWITCH (

        TRUE (),

        _getShippedDate - 2 >= _getPlanedDate

            && _getShippedDate - 2 >= _getCreateDate, "Late",

        _getShippedDate >= _getPlanedDate + 1

            || _getShippedDate = _getCreateDate + 1, "Backorder",

        _getShippedDate = _getCreateDate, "On-time",

        "CheckData"

    )
