Shift the values of clnd dimension of a measure

Hi,

We want to change the clnd dimension values of a measure.

We are getting the values of this measure from external system. One way is to use a script to change the values of the time(clnd) dimension which is simply a date here. If we want to achieve the same by an expression post loading the values of the measure, how exactly we can achieve that.

For example measure value: Measure intx is at day/item/store

Date,Prod,Store,Value

20200402,1289,21,5

Output (Date dimension- 5) for all the cells of the measure where dates is greater than x date. x could be any date
