Maximize Efficiency: Evaluating Multi-SKU Location Directives in Dynamics 365 Supply Chain

Table of Contents

The modern warehouse operates under increasing pressure to fulfill orders accurately and rapidly. A cornerstone of achieving this efficiency in Dynamics 365 Supply Chain Management’s Warehouse Management System (WMS) module is the proper configuration and functioning of Location Directives. These powerful tools guide workers through the process of picking items for sales orders, moving inventory, or putting away received goods, ensuring that the correct quantities are handled at the right locations.

Location directives are essentially sets of rules that the system follows to determine valid inventory locations during various work processes. They consist of a header, which defines the overall scope (like the work order type and warehouse), and lines, which specify sequences of conditions and actions. The goal is to direct warehouse personnel or automated equipment to the optimal storage or picking locations based on predefined criteria such as item attributes, location profiles, inventory status, and available quantity. Properly configured directives are crucial for minimizing travel time, optimizing space utilization, and improving overall throughput.

The Challenge of Multi-SKU Operations¶

Many modern distribution strategies involve handling multiple different Stock Keeping Units (SKUs) simultaneously. This is particularly prevalent in operations supporting e-commerce, retail store replenishment (often involving diverse product assortments), or light manufacturing/kitting processes. Scenarios like wave picking, where multiple orders or order lines are grouped for picking in a single pass, inherently involve handling multiple SKUs. Similarly, cluster picking, where items for several small orders are picked into separate containers during one trip through the warehouse, heavily relies on efficiently directing picks for diverse items.

Handling multiple SKUs efficiently within a single work process requires sophisticated logic. The system needs to consider the specific requirements and characteristics of each item being picked or put away. This might involve finding the best picking face for Item A, which is fast-moving and bulk-stored, while also finding a reserve location for Item B, which is slow-moving and requires specific temperature control, all within the same wave or put-away process. The ability to evaluate potential locations based on the distinct needs of multiple items concurrently is key to optimizing these complex workflows.

Configuring Location Directives for Multi-SKU¶

Dynamics 365 Supply Chain Management provides specific functionality to handle multi-SKU scenarios within location directives. A critical setting is the “Multiple SKU” option, typically found on the location directive line. When selected, this option signals to the system that the current directive line is intended to handle work involving more than one distinct item. This is designed to enable more complex evaluation logic, allowing the system to consider the collective requirements or characteristics of the group of items being processed.

Furthermore, a location directive line can have multiple associated “actions.” Each action represents a specific rule or set of criteria for finding locations. For instance, Action 1 might look for items in a ‘Picking’ zone, Action 2 might look in a ‘Bulk’ zone, and Action 3 might look in a ‘Reserve’ zone. When dealing with multiple SKUs, the expectation is that the system would evaluate each action associated with the selected line sequentially until suitable locations are found for all items or the necessary quantity is fulfilled, considering the specific queries and restrictions defined on each action. This iterative evaluation across multiple actions is fundamental to locating diverse items that might be stored in different types of locations based on velocity, size, or handling requirements.

Understanding the Specific Symptom¶

A reported issue within Dynamics 365 Supply Chain Management affects location directives configured for certain work types when processing multiple SKUs. Specifically, for location directives governing ‘Sales orders’ (as the work order type) and ‘Put’ (as the work type), there is a limitation when the “Multiple SKU” option is enabled on a directive line.

The symptom manifests as the system only evaluating the first action defined under that location directive line. Despite having multiple actions configured with different criteria intended to search various parts of the warehouse for the diverse items, the system halts its evaluation after processing only the initial action. Subsequent actions, designed to provide alternative search criteria or look in different location types/zones, are entirely ignored. This behavior prevents the system from performing the intended comprehensive search across multiple location types or criteria, which is essential for optimizing multi-SKU work.

Impact on Warehouse Efficiency¶

The inability of the system to evaluate multiple location directive actions in multi-SKU scenarios for Sales order picking and Put-away work has significant negative impacts on warehouse efficiency and operational flow.

• Suboptimal Location Selection: If the first action doesn’t identify suitable locations for all items (or the required quantities) within the multi-SKU group, the system may fail to find the best locations. For picking, this could mean directing workers to less efficient locations, skipping items that could have been picked from locations defined in subsequent actions. For put-away, it might result in inventory being directed to less appropriate reserve locations if the primary bulk or receiving locations (defined in later actions) are not considered.
• Increased Travel Time: Workers might be forced to travel further or make multiple trips if the initial locations provided by the first action are scattered or incomplete for the entire multi-SKU requirement. The intended benefit of grouping items for picking or put-away (like in wave picking) is diminished if the system cannot efficiently guide workers to consolidate these activities.
• Manual Workarounds: Warehouse staff may need to resort to manual processes or system overrides to find the remaining items or appropriate put-away locations that the automated directive failed to identify. This introduces delays, increases the risk of errors, and requires additional training and supervision.
• Disruption to Wave and Cluster Picking: These strategies are designed for efficiency in multi-SKU environments. When location directives fail to evaluate all relevant actions, the integrity of these processes is compromised, potentially leading to incomplete picks within a wave or cluster, requiring subsequent manual effort to complete the work.
• Reduced Throughput: The cumulative effect of suboptimal locations, increased travel, and manual intervention leads to a decrease in overall warehouse throughput. The system’s inability to perform its core function effectively acts as a bottleneck, limiting the volume of orders or inventory that can be processed within a given timeframe.

This limitation essentially undermines the power and flexibility that multi-SKU configuration and multiple actions are intended to provide within Location Directives.

Understanding the Need for Resolution¶

Addressing this symptom is critical to restoring the intended functionality and achieving maximum efficiency in warehouses utilizing Dynamics 365 Supply Chain Management for multi-SKU operations. The ‘Resolution’ in the system context typically refers to a fix or update provided by Microsoft to correct the erroneous behavior. For this specific issue, a resolution would involve ensuring that when the “Multiple SKU” option is selected on a location directive line for Sales order or Put work, the system correctly proceeds to evaluate all subsequent actions defined under that line, respecting their sequence, queries, and restrictions.

The objective of a resolution is to enable the system to perform a comprehensive search for the best locations based on the complete set of rules defined by the user across all relevant actions. This would allow businesses to leverage the full power of location directives for optimizing their multi-SKU picking and put-away processes, leading to:

• More accurate and efficient location assignments.
• Reduced travel time for warehouse workers.
• Improved utilization of warehouse space.
• Seamless execution of complex strategies like wave and cluster picking.
• Increased overall warehouse throughput and reduced operational costs.

Implementing a resolution would involve applying the necessary software update or hotfix provided by Microsoft. Businesses should consult official documentation or support channels to identify the specific update that addresses this symptom.

Best Practices for Multi-SKU Directives (Post-Resolution)¶

Once this specific issue is resolved, enabling the full evaluation of multiple actions for multi-SKU directives, organizations can implement best practices to maximize efficiency:

• Logical Action Sequencing: Structure your location directive actions in a logical sequence that reflects your desired picking or put-away strategy. For picking, this might mean checking high-velocity picking zones first, then bulk zones, then reserve zones. For put-away, it could be checking receiving zones, then bulk, then overflow/reserve.
• Specific Query Filters: Utilize powerful query filtering on each action to narrow down the search for locations based on specific criteria relevant to the items and the desired strategy. This could include filtering by location profile, zone, item attributes, quantity limits, or even inventory age (FEFO).
• Strategic Use of Strategies: Leverage the ‘Strategy’ field on location directive actions (e.g., FEFO, LIFO, Batch/Expiration, Consolidation, Empty location) to refine how locations are selected within the set of locations found by the query.
• Appropriate Quantity Limits: Define minimum and maximum quantities on actions to ensure that partial quantities or full pallets/cases are picked or put away from the most appropriate locations.
• Consider Location Profiles: Align location directive actions with your defined location profiles (e.g., PIcking, Bulk, Reserve, QA) to ensure items are directed to and from the correct types of locations.
• Leverage Work Breaking: For picking directives, configure work breaks strategically (e.g., by location, zone, or item) to create manageable work tasks for operators, even within large multi-SKU waves.

By combining the corrected system behavior with careful design based on these principles, businesses can unlock significant efficiencies in their warehouse operations, particularly those dealing with high volumes of diverse items.

Testing and Deployment Considerations¶

Applying any system update or hotfix, including one addressing this location directive symptom, requires careful planning and execution. It is imperative to:

1. Test in a Non-Production Environment: Always apply the resolution (hotfix/update) first in a test or quality assurance environment. This allows you to verify that the symptom is resolved and, critically, that no new issues have been introduced and that your existing location directive configurations function as expected with the corrected behavior.
2. Validate Key Scenarios: Test your most common and complex multi-SKU picking and put-away scenarios. This includes testing waves with various item combinations, quantities, and location types.
3. Involve Key Users: Have experienced warehouse users and system administrators participate in the testing process to ensure the resolution meets operational requirements and expectations.
4. Plan Production Deployment: Once thorough testing is complete and successful, plan the deployment to your production environment during a scheduled maintenance window to minimize disruption.
5. Monitor Post-Deployment: After the resolution is live in production, monitor warehouse operations closely to ensure the intended efficiency gains are realized and that no unexpected issues arise.
