How to carry out C4C Cloud Application Studio to do ABSL development performance best practices, I believe that many inexperienced people do not know what to do, so this paper summarizes the causes of the problem and solutions, through this article I hope you can solve this problem.

How to call BO action in batch

Bad examples:

The first and fourth lines have two loops, and then in the second loop, a standard action FinishFulfilmentProcessing defined on the item node of the more time-consuming ServiceRequest BO is invoked. The time complexity of the code is o (N2)

The right thing to do:

The principle of optimization is that, like many other Netweaver-based SAP products, the core service of C4C's BO supports batch operations. The so-called batch operation technically means that the input parameters of these service are an internal table, not a single piece of data. If you have done CRM development, you can compare CRM_ORDER_MAINTAIN to this function module, where all the input parameters are inner table structures. The interface definition of service provided by BO of C4C also fully adopts this design which supports batch operation.

In the bad example above, the pseudo code of the compiled ABAP code is as follows: (because the background code of C4C is not open to Partner and customers, I can only provide pseudo code). You can see that although the action of BO performs batch operations, this writing does not play the role of batch operations. Each time the internal standard of the input parameter inside the loop is cleared in the second line, there is only one record of the input parameter each time BO action is called.

For the correct example, the pseudo code generated after compilation is:

You can clearly see that the execution of the BO action has been placed outside the loop.

How to execute BO Retrieve in batch

When we try to call BO's Retrieve method through code completion in Cloud Studio, IDE prompts us that the Retrieve method has three overloads (Overload), indicating that Retrieve can support passing different parameters.

The correct and unrecommended practices are shown in the blue and red codes in the following figure, respectively. You can see that the input parameter accepted by the blue code retrieve is a collection containing two elements with ID 3 and 4, so that the 41-line call can return 2 ServiceRequest data at a time.

Pseudocode for ABAP code generated after line 43 compilation:

Pseudo code for ABAP code generated after line 41 compilation:

By comparison, we can find that if the parameter passed in retrieve is a collection of ID, then the compiled ABAP code will call a retrieve method with the interface of the inner table to read the data in batches.

How to execute BO Create in batch

For the basic Create operation, see line 54 below, which only supports data creation based on a single node.

But for the CreateWithReference scenario, like the Retrieve scenario in the second example, you can pass in not only a single data (line 56), but also a collection (line 58).

These two different inputs will cause the compiled ABAP code to enter the execution logic of CREATE_WITH_REF_1 and CREATE_WITH_REF_N respectively, resulting in performance differences.

After reading the above, have you mastered how to implement C4C Cloud Application Studio to do performance best practices in ABSL development? If you want to learn more skills or want to know more about it, you are welcome to follow the industry information channel, thank you for reading!
