editing time dependent materiel values

im assigning recharge in time series(in/out flow on top of model) as tshape files with polygon in it. she polygon is assigned with a series. is there any easy way to change recharge for a particular polygon  rather than editing shape file  table in arcgis and importing it. since imdoing calibration i want to try different percentage of recharge in different geological formation. when i try to edit values by giving an expression for eg Q=Q/2 for a perticular region by using polygon selection, the new value is not applied throughout time steps. it is applied only to current time step.
any help pls?

Please check the budget rather than the distribution. The distribution is not updated.

i think you didnt get my question. im assigning recharge as shape file of polygon with each polygon means diffrent time series. now for example i wan to run model with 50% of recharge for a particular region, i need to edit shape file time series given for tht particular polygon in arcgis. is there any way to edit times series in feflow itself?
when i select a region and give expression q=q/2 it wont edit the time series, it only edit active day.. in that way i need to apply for all the day

Yes, that's possible. You may create an Elemental User Distribution in the Data panel. Use different ID's (integer) for different Areas Of Interest (AOI's). After that, right click on In-/outflow on top/bottom and choose [b]Edit Parameter Expression...[/b].

Here is an example expression:
[font=courier]
TS.1 * 0.5 if ED.1 = 1
TS.1 otherwise
[/font]
TS.1 is the time-series and ED.1 is the elemental user distribution.

thank you so much  :)

what if thre is two or more times series under one polygon.
for example 3 rainstations under one geological area

I am not sure, whether or not I understood your question correctly. You stated at July 02, 2018, 06:10:38 AM that you have for each polygon a different time-series. Is this still the case and you need to extend the expression to three or more zones / Area Of Interests (= three or more time-series multiplied with a separate factor).

time  series is applied as polygons using link parameters, not using time series ID. so i cant apply T.S equation in it
