SAP WebI 4.x Syntax Input

Standard Syntax: [Measure] Where ([Dimension])

Example Variations:

=[Revenue] Where ([Country]="US")
=Sum([Revenue]) Where ([Year]=2024 And [Country]="US")
=[Revenue] Where ([Country] InList("US";"UK"))
=[Revenue] Where (Not([Country]="US"))
=[Revenue] Where ([Flag])
=[Revenue] Where ([Year]=Year(CurrentDate()))

Power BI DAX Equivalent Output Measure

Compiled DAX Measure:

Revenue = 
CALCULATE(
    'Sales'[Revenue],
    KEEPFILTERS('Sales'[Country]="US")
)

Context Explanation:

WebI "Where (condition)" operator maps directly to DAX "CALCULATE(..., filter)".

Enterprise Migration Note: Context Transition in Power BI

When migrating Where from SAP BusinessObjects universes to Power BI, keep in mind that WebI evaluates context operators at the report display layer (block, break, section), whereas Power BI evaluates DAX against a tabular tabular model using row context and filter context.

1. Use KEEPFILTERS

Wrap filter arguments inside KEEPFILTERS to avoid inadvertently overriding existing dashboard slicers.

2. Explicit Measures

Always define calculations as explicit DAX measures rather than calculated columns to maintain optimal VertiPaq compression.

3. Table Name Prefix

Reference columns using 'TableName'[Column] and measures as [MeasureName] following Microsoft architecture guidelines.
