If statement (greater than) different tables

[HeShootsNScores]

Hi - 

Been pounding my head against this for weeks.. hopefully someone can help. I'm trying to calculate whether or not we've placed PO's at or before the required lead time.

I have 3 tables:

Vendor

PurchaseOrderHeader

PurchaseOrderDetail

The StandardLeadTime column is in the Vendor Table

and the Lead Time on PO column is a calculated colum in the PurchaseOrderDetail table

Lead Time on PO = DATEDIFF(RELATED(PO_PurchaseOrderHeader[DateCreated]),PO_PurchaseOrderDetail[UDF_ON_DOCK_ETA],DAY)

What I want to figure out, is how to make a caculated column that says IF the number in the Lead Time on PO (in the PurchaseOrderDetails Table) >= the number in the StandardLeadTime column (in the Vendor Table), "Yes", otherwise, "No"

I keep getting this

Hi @HeShootsNScores ,

Model 1

Result1

Model2 

Result2

RELATED() 

Try to create a measure like this.

Measure 2 = 
VAR x = 
CALCULATE(
    SUM(Vendor[Value]),
    FILTER( Vendor, Vendor[ItemCode] = SELECTEDVALUE(Vendor[ItemCode]))
)
RETURN
IF(
    SELECTEDVALUE(PurchaseOrderDetail[Value]) >= x,
    "Yes", "No"
)

Or Create a calculated column like this.

Column 2 = 
VAR x = 
CALCULATE(
    SUM(Vendor[Value]),
    ALLEXCEPT(PurchaseOrderDetail, PurchaseOrderDetail[ItemCode])
)
RETURN
IF(
    PurchaseOrderDetail[Value] >= x,
    "yES", "nO"
)

This worked! Your model 2 calculated column worked. Thank you!

Your relationship is going in the wrong direction to be able to use RELATED() against the vendor table. The way you have the relationships modelled is effectively saying that one purchase order line can be related to many different vendors. This does not sound correct to me.

If you edit this relationship and change the cardinality from many-to-one to one-to-many  (or vis-versa) this will switch the From/To columns and the RELATED() function will then be able to function as you expect.

Is it a 1:many relationship between Vendor and OrderDetail tables?  Is itemcode the same data type on both sides of the relationship?   If so, Related should work. If not, you'll need to change it to that or use RELATEDTABLE() and an aggregation.
