Help with Crossfiltering across multiple tables

[larbpup]

Hello,

I have a fact table of forecasted sales orders and a table of part numbers with corresponding production rates. I would like to calculate the amount of total production hours needed per month by multiplying the forecasted sales amount by the part work rate. Unfornunately I am not able to achieve this without setting all my relationships to bidirectional, which will not be useful going forward as I would like to add in additional tables and info for drilling down, etc.

I am attempting to use measures with CROSS FILTER, but I am not very knowledable with it. How would I get the cross filter to go across multiple tables?

Thanks.

Ex: only between two tables.

ForecastedBacklog = CALCULATE([Backlog_Units_Total],CROSSFILTER(DateDimension[Date],SalesOrder_Backlog[SchedDate],BOTH))

Ideal output (MonthYear col is from the date dimension table):

Relationships:
DateDimension -> SalesOrder_Backlog by Date to SchedDate

SalesOrder_Backlog ->PartTable by PartId

PartTable ->PartWorkRate by PartId
PartWorkRate -> Workcenter by Workcenter Id 

WorkCenter -> Line by an index that I derive from a lookup table.

Hi @larbpup I personally do not use bidirectioanal relationship as ambigious result could emerge, I rather rework model if possible. Still, with my little knowledge of this area, could you please check part ,BOTH)) in your crossfilter function. Maybe this could help in debuging your wanted output, give a try to change this part.  Great link for crossfilter is below, with other usefull link
