Aggr() function with aggregation dimension

[StacyCui]

Hi, We have a request.  We have some products . For the red one, we need aggregate together as a new dimension. For the new dimension, the calculate logic is also different with other dimensions. 

here comes my expression:

Dimension:

=if(WildMatch(DE,'FA DE Enabled' ,'FA DE Design' ,'FA DE' ,'FA DE Edge&AI' ,'FA DE Design Service Enable' ,'FA Digital Solution')>0 ,'FA Digital Solution' ,DE)

Measure:

if(WildMatch(DE,'FA DE Enabled' ,'FA DE Design' ,'FA DE' ,'FA DE Edge&AI' ,'FA DE Design Service Enable' ,'FA Digital Solution')=0
,sum(aggr(Sum({<[FiscalYear]={$(v_CurrentYear)}>}[OR Value RMB]),DE)),
Sum({<[FiscalYear]={$(v_CurrentYear)},DE={"FA DE Enabled"}>}FA_DE_Enable_OR)
+Sum( {<[FiscalYear]={$(v_CurrentYear)},DE={"FA DE Design"}>}[OR Value RMB])
+Sum({<[FiscalYear]={$(v_CurrentYear)},DE={"FA DE Design Service Enable"}>}FA_DE_DesignServiceEnable_OR)
+Sum({<[FiscalYear]={$(v_CurrentYear)},DE={"FA DE Edge&AI"}>}[OR Value RMB]))

I found it changes after I select one category. Is it related to aggr() ? 

If I delete aggr() function in the measures expression as follow. For some category, It could not be aggregated. How to solve it? Thanks so much.

if(WildMatch(DE,'FA DE Enabled' ,'FA DE Design' ,'FA DE' ,'FA DE Edge&AI' ,'FA DE Design Service Enable' ,'FA Digital Solution')=0
,Sum({<[FiscalYear]={$(v_CurrentYear)}>}[OR Value RMB]),
Sum({<[FiscalYear]={$(v_CurrentYear)},DE={"FA DE Enabled"}>}FA_DE_Enable_OR)

+Sum( {<[FiscalYear]={$(v_CurrentYear)},DE={"FA DE Design"}>}[OR Value RMB])
+Sum({<[FiscalYear]={$(v_CurrentYear)},DE={"FA DE Design Service Enable"}>}FA_DE_DesignServiceEnable_OR)
+Sum({<[FiscalYear]={$(v_CurrentYear)},DE={"FA DE Edge&AI"}>}[OR Value RMB]))

HI 

I would look at starting to address this in the Script. Make you new grouping as a new Dimension, then you can look at making the set analysis easier in the front end with an if based around the new dimension
