Calculate with multiple tables

[Frankcf]

I have set up a report that required that i link 5 tables. Each table is responsible for an inventory count.

Main table is item, that all tables are related to

1. table  1 is "inventroy_Qty displays current inventroy amount
2. table 2  is "PO_Qty" displays the quantity on purchase order
3. table 3  is " Prod_Qty" displays the quantity on a production order
4. table 4  is "Sales_Qty" displays the quantity on sales order (not shipped)

the problem is that i need to calculate what is available to be sold

to accomplis this i am using the follwing formula in excel

(inventory_qty + po_qty) - (Prod_qty + Sales_Qty) = Available_Qty.

how can i perform this calculatin in Power BI. using BI desktop.

Hi @Frankcf,

Based on my understanding, I build below sample, you can refer to it:

Tables.(t1,t2,t3,t4)

Table formula:

Avible Inventory =
SELECTCOLUMNS(Sheet1,"Inventroy ID",[Inventroy ID],"Inventory Name",[Inventory Name],
"Avible Qty",([Inventroy Qty]+ SUMX(FILTER(ALL(Sheet2),Sheet2[Inventory ID]=EARLIER(Sheet1[Inventroy ID])),[PO_Qty]))
-(SUMX(FILTER(ALL(Sheet3),Sheet3[Inventory ID]=EARLIER(Sheet1[Inventroy ID])),Sheet3[Prod_Qty])+SUMX(FILTER(ALL(Sheet4),Sheet4[Inventory ID]=EARLIER(Sheet1[Inventroy ID])),Sheet4[Sales_Qty])))

The detail result table:

Avible Inventory =
SELECTCOLUMNS(Sheet1,"Inventroy ID",[Inventroy ID],"Inventory Name",[Inventory Name],
"Avible Qty",([Inventroy Qty]+ SUMX(FILTER(ALL(Sheet2),Sheet2[Inventory ID]=EARLIER(Sheet1[Inventroy ID])),[PO_Qty]))
-(SUMX(FILTER(ALL(Sheet3),Sheet3[Inventory ID]=EARLIER(Sheet1[Inventroy ID])),Sheet3[Prod_Qty])+SUMX(FILTER(ALL(Sheet4),Sheet4[Inventory ID]=EARLIER(Sheet1[Inventroy ID])),Sheet4[Sales_Qty])),
"Qty_T1",Sheet1[Inventroy Qty],
"Qty_T2",SUMX(FILTER(ALL(Sheet2),Sheet2[Inventory ID]=EARLIER(Sheet1[Inventroy ID])),Sheet2[PO_Qty]),
"Qty_T3",SUMX(FILTER(ALL(Sheet3),Sheet3[Inventory ID]=EARLIER(Sheet1[Inventroy ID])),Sheet3[Prod_Qty]),
"Qty_T4",SUMX(FILTER(ALL(Sheet4),Sheet4[Inventory ID]=EARLIER(Sheet1[Inventroy ID])),Sheet4[Sales_Qty]))

Result:
