Circular dependency in invetory calculate

[William_Moreno]

Hello everyone,
I need to build a formula in the powerbi to calculate the openning inventory, but if the date is not the same as today, this should consider t of closing inventory of the previous day.
When I try to do this the powerbi mesage is circular dependecy,
Below follow a example:

Unit	Product	Date	Openning Inventory	Manufacturing product	Sales	Closing Inventory
Dallas	XFG044	21/12/2020	792	180	10	962
Dallas	XFG044	22/12/2020	962
Dallas	XFG044	23/12/2020
Dallas	XFG044	24/12/2020
Dallas	XFG044	25/12/2020

Can someone help me?
Thanks in advanced.

Hi  @William_Moreno ,

I customize the data of manufacturing products and sales：

Here are the steps you can follow：

1. Enter power query through transform data and select add column --- index column --- from 1 to generate the index

2. Create Measure.

Closing Inventory_measure =
var _index=MAX('Table'[Index])
var _1=CALCULATE(SUM('Table'[Openning Inventory]),FILTER(ALL('Table'),[Index]<=_index))
var _2=CALCULATE(SUM('Table'[Manufacturing product]),FILTER(ALL('Table'),[Index]<=_index))
var _3=CALCULATE(SUM('Table'[Sales]),FILTER(ALL('Table'),[Index]<=_index))
var _result=_1+_2-_3
return
IF(MAX('Table'[Index])=1,962,_result)

Openning Inventory_measure =
var _1=
CALCULATE([Closing Inventory_measure],FILTER(ALL('Table'),[Index]=MAX([Index])-1))
return
IF(MAX('Table'[Index])=1,792,_1)

3. Result：

You can downloaded PBIX file from here.

@William_Moreno , Try meausre like

Openning Inventory =
var _min = minx(all(Table), Table[Month]) //or use date
return
calculate(sum(Table[Openning Inventory]), filter(Table, Table[date] =_min)) - calculate(sum(Table[ Manufacturing])-sum(Table[product Sales]), filter(Table, Table[date] <max(Table[date)))

Openning Inventory =
calculate(sum(Table[Openning Inventory]), filter(Table, Table[date] =calculate(min(Table[date]), allexpcept(Table,table[Product]))) - calculate(sum(Table[ Manufacturing])-sum(Table[product Sales]), filter(Table, Table[date] <max(Table[date)))
