Calculate a column with multiple values

From nav i am making a report in Power BI. The nav report i want to recreate has multiplte filters for different columns. 

Salestype A = Column 1: A,B
                Column 2 100,200
                Column 3: "SupportX" or "Support Y"
Salestype B = Column 1: A,C
                       Column 2: 100,300
                       Colum3: "ERP1" or "ERP2"

Now i have created measures and that gives me the right values:

Saletype A = [Total amount]
(FILTER (Ledger entries; Ledger entries [Revenue Distribution] = "VA SUPPORT");
FILTER (General ledger entries; General ledger entries [Cost center Code] = 2,000);
FILTER (General ledger entries; General ledger entries [AggregationTF] = 1) 

Salestype B = Business apps hours = [TotalAmount]
(FILTER (Ledger entries; Ledger entries [AggregationTFBusiness apps] = 1);
FILTER (General ledger entries; General ledger entries [CostPlaceFiltering] = 1);
FILTER (Ledger entries; Ledger entries [RevenueDistributionFiltering] = 1)
)

 But to optimally use PowerBi I would like to create a (calculate)column what says me what salestype it is. In total i have arround 20 salestypes.  What is the best solution for this?
