Custom Filter for RankX new Column

[Anonymous]

I currently have a large table that requires a visualised index column. I have come across this EXAMPLE formula for a RANKX and FILTER for a new column in the table :

RANKX(

FILTER(

‘Sales Table’,

‘Sales Table'[Country ] = EARLIER(‘Sales Table'[Country ])

),

‘Sales Table'[Total Sales]

)

but I'm struggling to replicate it with my data:

Supplier Analysis Index Rank = RANKX(FILTER('looker_views lkr_Intake_Data','looker_views lkr_Intake_Data'[Supplier Group Name] = EARLIER('looker_views lkr_Intake_Data'[Supplier Group Name],

'looker_views lkr_Intake_Data'[Intake_Data_Custom_1] in {"COP1","COP2"}))

My aim is to have this formula:

Supplier Analysis Index Rank = RANKX(ALL('looker_views lkr_Intake_Data'[Supplier Group Name]),'looker_views lkr_Intake_Data'[Company_Id],,ASC)

Only filtered for: 

'looker_views lkr_Intake_Data'[Intake_Data_Custom_1] in {"COP1","COP2"})

Can anyone help?
