In the Warehouse Management mobile app for Dynamics 365 Supply Chain Management, it is currently not possible to use a data inquiry (detour) to look up and return a value (e.g., Load ID) into a system grouping field.

This creates a limitation when using system grouping (e.g., Load ID) in combination with detour-based lookup scenarios, which are widely used for efficient warehouse operations.

Business Scenario

Warehouse workers need to perform picking based on a specific Load ID, where:

Work is grouped using system grouping = Load ID

A detour (data inquiry) is used to look up active loads

The worker selects the correct Load ID from the detour

The selected value should be returned automatically to the calling step

This flow is already a natural and supported design pattern in the mobile app — but currently does not work when combined with system grouping.

Current Limitation

Today, the system:

Does not support returning values from a detour into a system grouping field

Forces users to manually re-enter or scan the Load ID

Effectively requires entering the same value twice

Microsoft support has confirmed this as a functional limitation and product gap with no current fix available.

Business Impact

This limitation has significant operational impact:

Breaks system-driven picking flows

Introduces manual steps in otherwise automated processes

Increases risk of user errors (wrong Load ID)

Reduces warehouse efficiency and scanning accuracy

Makes system grouping unusable for load-based picking scenarios

As a result, customers must choose between:

Using system grouping (but losing lookup capability)

Or using manual entry (losing control, automation, and efficiency)

Expected Behavior

The system should support:

Using a detour (data inquiry) to look up values (e.g., Load ID)

Returning the selected value to:

The system grouping field, or

The corresponding input field in the main workflow

Allowing full integration between:

System grouping

Detours (lookup)

Paste-back / return values

Proposed Enhancement

Introduce support for:

Mapping a field from a detour result back to:

System grouping fields

Or input parameters used for grouping

Ensuring compatibility between:

Display Open Work List (system grouping)

Data Inquiry detours

Standardizing this as a supported pattern in WHS mobile flows

Why This Matters

This is a core warehouse scenario, especially in environments with:

Load-based outbound processes

High-volume picking operations

Automation and system-directed flows

Without this capability, customers are forced into workarounds that:

Degrade process quality

Reduce system adoption

Increase operational risk
