Optimizing Custom Alerts in SAP Supply Chain Control Tower

In today’s fast-paced business environments, supply chain management is increasingly complex and challenging, requiring new forms of technological aid. SAP Supply Chain Control Tower has gained traction in recent years, helped by its advanced functionalities including artificial intelligence and machine learning capabilities. This lesson focuses on the role of machine learning in the SAP IBP Supply Chain Control Tower and its importance for beginners eyeing to excel in supply chain procedures.

Machine Learning, a subset of Artificial Intelligence, is about designing systems that can learn from and make decisions based on data: it involves processing large volumes of data and learning from this information to make accurate predictions. It is these capabilities that make it an integral part of the SAP Supply Chain Control Tower.

Within the Control Tower, machine learning can improve supply chain planning processes by predicting future outcomes and prescribing solutions based on historical data. The system analyses past data trends related to sales, inventory, production, demand, and supply among other factors and then uses this information to make precise predictions about the supply chain operations. This helps businesses to respond proactively and make informed decisions, enhancing the efficiency and productivity of the overall supply chain.

In addition to predictive analysis, machine learning algorithms can also be used for anomaly detection. Within complex supply chains, unexpected disruptions can have significant impacts. Being able to detect anomalies and unusual data patterns can therefore save businesses from substantial losses. Anomalies could include sudden changes in demand patterns, disruptions in the supply chain, or unexpected events like machine breakdowns or natural disasters.

Besides of SAP Supply Chain Control Tower, Machine learning also plays a significant role in demand sensing within SAP IBP for Demand. Demand sensing involves machine learning to analyze real-time sales data, complemented by factors such as market trends and economic conditions. This analysis improves forecast accuracy, enabling businesses to effectively adjust their supply chain strategies.

Furthermore, machine learning in the SAP Supply Chain Control Tower can lead to better data quality. It can detect and correct potential errors in data input and thus improve the integrity of information used in supply chain planning.

In a nutshell, machine learning in the SAP Supply Chain Control Tower provides several opportunities to improve supply chain operations. Its predictive abilities, anomaly detection, enhanced data quality, and real-time demand sensing lead to improved productivity, efficiency, and decision-making. This makes machine learning an immensely powerful tool for supply chain planners, even for those beginning their journey in this field.

As beginners navigate their ways through the complexities of supply chain procedures, understanding the machine learning functionality in SAP IBP Supply Chain Control Tower could be a major step forward. The above points underline just how valuable machine learning can be for proactive planning, anomaly detection, high-quality data, and improved decision-making. Beginners can use these insights to harness this powerful technology and get a head start in managing supply chain processes in much more efficient, informed, and innovative ways.

The basic custom alert definition is based on static rules. This works fine if the threshold for the exception condition is known and the data is generally consistent.

If the data is variable and changes to the pattern occur, the static rules may lead to too many or too few alerts. With machine learning, planners can set up alerts without needing to know the exact thresholds.

For example, if you define alerts for your product's sales quantity based on ABC indicator, the rules would be different for Product A (a fast seller), which could be set at 5 percent decline in sales, than for product C, (a slow seller), which could be set for 20 percent decline in sales. This would result in several different alerts to provide the same result, which is to indicate that there has been a drop in your sales quantity. With machine learning, the grouping of your ABC products can be done automatically. Similarly, it allows you to find the outliers in the groupings.

Parameters can be set to get a "healthy" amount of alerts.

Machine Learning adjusts with changing data patterns.

Users can either use ML alert definitions on their own or put them on top of existing alerts with static rules.

You can apply one of the two clustering-based algorithms – k-means or density-spaced spatial clustering of applications with noise (DBSCAN). The number of alerts can be reduced or increased. These types of rules are mainly used for detecting outliers, when you do not know in advance your threshold values, and when the data shifts over time. Additionally, if you change data, the alert definition is automatically adjusted.

The DBSCAN and k-means clustering methods are used to find and group points on a chart that are close together. They also help in identifying the outliers (isolated points in low-density regions outside the groupings).

When working with very large numbers of records, it is recommended to schedule the jobs to improve performance of the alerts monitor, because the operation will time out after ten minutes. When the job to retrieve outliers is scheduled, the results are stored in a buffer, which makes the results faster and easier to retrieve.

DBSCAN requires a minimum of 25 distinct records to be able to complete the clustering accurately. Where there are fewer records, the results are insignificant. For example, you have defined an alert based on PRODID, LOCID, and Day aggregation level. You need at least 25 distinct records to use DBSCAN with the PRODID as an aggregated attribute. In other words, for each product you should have a combination of records of at least five days and five locations.

The DBSCAN algorithm checks attribute groupings and performs clustering on these attributes. In addition to performing outlier determination on one key figure, it uses multiple attributes during the calculation process that make it more accurate than the k-means algorithm.

The second machine learning algorithm which can be used for defining custom alerts is the k-means algorithm. In contrast to DBSCAN it only uses key figure values and does not consider attributes. The algorithm is also used in the ABC/XYZ segmentation to find clusters based on the segmentation measure’s demand value for ABC and volatility for XYZ.

The following simple example shows the difference in identification and detection of outliers, which then are marked as an alert.

DBSCAN: The algorithm first checks the quantity key figure and then checks the ABC indicator attribute. As a result, the algorithm identifies the only value of 100 for ABC indicator A as an outlier.

K-means: Since k-means uses only numerical values in the calculations, the ABC indicator attribute is ignored by the algorithm and only the quantity key figure is considered. As a result, an outlier can’t be identified since there are multiple records with the same values.

I was part of a team managing a complex supply chain that experienced significant delays in material delivery, leading to production halts. The root cause was an unexpected shortage of a key component. At the time, our reaction was reactive rather than proactive, as we lacked real-time visibility and alerting mechanisms.

Applying the concepts of the SAP Supply Chain Control Tower and its custom alerts, we could have significantly mitigated this issue. By defining threshold values for inventory levels of critical components, custom alerts would have notified us well in advance of the shortage, allowing for proactive measures. Specifically, we could have identified alternative suppliers or adjusted production schedules to minimize the impact.

Moreover, integrating machine learning for dynamic alert adjustment could have further enhanced our response. Given the variability in demand and supply, static thresholds might not always capture the nuances of our supply chain dynamics. Machine learning algorithms like k-means or DBSCAN could have adjusted these thresholds based on emerging data patterns, offering more timely and relevant alerts. This capability would have not only addressed the immediate challenge but also continuously optimized our alerting system for future anomalies.
