Kinaxis KX3-003 - Certified RapidResponse Author Level 3 Exam

To ensure that neither worksheet is taking advantage of cached results, which could skew performance comparisons, you should close the workbook and any library workbooks it depends on. By reopening the workbook after this, you force RapidResponse to reload the data and recalculate the worksheets from scratch, ensuring that you are capturing performance results without the influence of previously cached data.

ReferencesKinaxis RapidResponse performance tuning guidance suggests that to accurately test the performance impact of changes, all cached data should be cleared. This can be achieved by closing and reopening the workbooks, as indicated in the Kinaxis RapidResponse resources on performance management.

To ensure unique key values while saving memory, it's best to concatenate critical fields that together provide uniqueness. The expression A combines the Part Site Value and the Effective In Date, providing a string that will be unique across all parts and their effective dates. This approach is more memory-efficient than storing additional redundant data or using less discriminative fields.

B is not specific enough, as EffectiveInDate alone does not guarantee uniqueness across parts and sources. C is potentially unique, but it may not be as memory-efficient as A if Part Names are long strings. D is not specific enough, as the Source ID alone does not ensure uniqueness across parts.

The ListAsSet function in Kinaxis RapidResponse expects a set of elements as input, typically in the format of a string with elements enclosed in single quotes and separated by commas. For a user that should see data for suppliers A, B, and C, you need to format the string to match this expected input format.

To optimize performance when creating a worksheet that contains fields from four tables, the worksheet should be based on:

Table 1

Table 1 is connected to Table 3 with a one-way arrow, indicating a one-to-many relationship where Table 1 is the primary table. This setup typically allows for more efficient data retrieval and better performance.

References

The decision is supported by the diagram showing the relationships between the tables, where “Arrow Head = 1” and “Arrow Base = Many” indicates the direction of the relationship and the primary table.

To optimize performance, the worksheet should be based on the top-level table from which you can access related data via references. This is because starting from the top level allows you to utilize indexed lookups, which are faster than traversing from many-to-one relationships. Given the data model design, Table 1 is the topmost table with one-to-many relationships to Table 3, which in turn links to Table 4, and it can also indirectly access data from Table 2 through the many-to-one relationship back to Table 1.

Matching the sort order and direction in both component worksheets before creating a composite worksheet can improve performance. This alignment ensures that the composite worksheet does not have to re-sort the data from each component worksheet, which can be computationally expensive, especially for large datasets.

ReferencesThe recommendation to match sort orders and directions for performance optimization in composite worksheets is in line with best practices for data management in Kinaxis RapidResponse, which can be found in the training and documentation materials.

In the context of creating a metric worksheet for calculating the number of late orders, you want to group by DueDate to consolidate orders that are due on the same day, and then sum the Count for each of these groups to get the total number of late orders per day. Therefore, DueDate should be the grouping column, and Count should use the Sum function to add up all instances of late orders for each DueDate.

The expression to display the number of the calendar week from the beginning of the year takes today's date, resets it to the start of the year (the 0 Year part), and then calculates the week number from this start date, adding 1 since week numbers generally start at 1, not 0.

ReferencesThe logic for calculating week numbers from a given date is commonly described in Kinaxis RapidResponse documentation and training materials concerning date and time functions.

The migration of the Supplier.Id filter to the secondary filter expression box allows for enabling caching because it is a user-specific filter. Moving user-specific or session-specific expressions to the secondary filter ensures that the primary filter canbe cached independently of user sessions. This way, the overall data set can be cached, and the user-specific filtering is applied afterward, improving performance.
