Create a variable measure which does not gets affected by a date slicer

Hi All and v-xiaotang 

I want to retrieve the last date target value for each sub-category (like 40 for product X and 28.44 for Product Y), in such a way that it is not affected by slicer. My aim is to plot a chart showing three values on combo chart with sub-cateogory on x-axis

actual = 11.32 (X) and 15.33 (Y)

target = 13.32 (X) and 17.33 (Y)

planned = 40 (X) and 28.44 (Y)

I put a slicer on combo chart in such a way that the actual and target value varies according to the date but the planned value is a line chart and stays constant, no matter whatever date is chosen on a slicer.
