What IF Parameters not working when unpivoting the Measure to Rows

[PK_PBIBoss]

Hi All

I am stuck at a point when I created the output of WhatIF Measure it works fine here :- 

	Slicer XXX = -8	Slicer YYY = -10	Slicer ZZZ = -11	Slicer AAA = -65
	FY 2018	FY 2019	FY 2020	Revised
XXX	80.00	85.00	70.00	62.00
YYY	70.00	85.00	65.00	55.00
ZZZ	80.00	85.00	63.00	52.00
AAA	80.00	85.00	5.00	(60.00)

JFYI Measure Formula = 

SUMX(Total, IF(Total[Financial Item] = "XXX" , FY 2020 +  'Slicer XXX'[Change Value]),IF(Total[Financial Item] = "YYY" , FY 2020 +  'Slicer YYY'[Change Value]) ,IF(Total[Financial Item] = "ZZZ" , FY 2020 +  'Slicer ZZZ'[Change Value]) , IF(Total[Financial Item]= "AAA" , FY 2020 +  'Slicer AAA'[Change Value]) ),FY 2020)))))

But when I try to Unpivot Table in the below manner with these Measure it does not update Slicer Value

Summarize Table =

VAR Counter = COUNTROWS(FILTERS('P&L'[Business Line]))

VAR T1 = SUMMARIZE(Total,Total[Business Line],Total[Financial Item],"Year","FY 2018", "Value", Total[Total FY 2018])

VAR T2 = SUMMARIZE(Total,Total[Business Line],Total[Financial Item],"Year","FY 2019", "Value", Total[Total FY 2019])

VAR T3 = SUMMARIZE(Total,Total[Business Line],Total[Financial Item],"Year","RFC 2020", "Value", Total[Total RFC 2020])

VAR T4 = SUMMARIZE(Total,Total[Business Line],Total[Financial Item],"Year","Revised RFC 2020", "Value",

SUMX(Total, IF(Total[Financial Item] = "XXX" , FY 2020 +  'Slicer XXX'[Change Value]),IF(Total[Financial Item] = "YYY" , FY 2020 +  'Slicer YYY'[Change Value]) ,IF(Total[Financial Item] = "ZZZ" , FY 2020 +  'Slicer ZZZ'[Change Value]) , IF(Total[Financial Item]= "AAA" , FY 2020 +  'Slicer AAA'[Change Value]) ),FY 2020))))) )

RETURN

UNION(T1,T2,T3,T4)
