Performing the Code Inspector Check

The Code Inspector enables you to analyze your customer objects for critical usages of SAP objects simplified with, for example, SAP S/4HANA. Each finding of the Code Inspector checks has to be analyzed and potentially adapted to the simplification made in SAP S/4HANA.

Prerequisites

To run ad hoc inspections as a developer, you need the authorization for authorization object S_TCODE with value SCI for field TCD.
To define and run re-usable, global system inspections, approve exceptions, and perform other Quality Manager tasks, you need the authorization for object S_COV_ADM with value * for field ACTVT.

Context

You perform the Code Inspector check to investigate the relevant customer objects to be adopted in order to migrate your custom code to SAP S/4HANA.

Procedure

To start the Code Inspector, run transaction SCI.

The Code Inspector: Initial Screen is opened.
To create an object set for the development objects to be analyzed, enter the name of the object set to be created in the Name input field of the Object Set section.
Choose the Create button.
The Code Inspector: Object Set screen is opened.
To analyze your objects in your SAP Business Suite system, the following scenarios might be relevant for you to continue:
1. Variant 1: You have already converted your SAP Business Suite system to SAP S/4HANA, then proceed as follows:
  1. On the Select Object Set tab, enter the relevant packages in the Package input field, for example Z*, Y*, /YOUR_NAMESPACE/*.
2. Variant 2: Your SAP Business Suite System is not yet converted to SAP S/4HANA. You perform the check in your evaluation system based onSAP NetWeaver 7.5. Then, the Code Inspector will access the objects in your SAP Business Suite system through a remote connection. In this case, proceed as follows:
  1. On the Obj.Collectors tab, position the cursor in the Object collector input field and choose F4.
    The Object Collectors dialog is opened.
  2. Select the Remote Objects (RFC) entry and confirm your selection.
    The Parameter dialog is opened.
  3. In the Destination input field, enter the name of the RFC destination or choose F4 to search for the relevant one.
  4. Confirm your selection.
    The Remote Objects (RFC) object collector is added.

  5. In the Package input field, enter the relevant packages, for example Z*, Y*, /YOUR_NAMESPACE/*.
To trigger creation of the object set, save your input.

The object set is saved.
Navigate back to the Code Inspector: Initial Screen.
To analyze the objects contained in the created object set with the checks configured in the generated check variant, you have to create a Code Inspector inspection. To do this, enter the name of the inspection to be created in the Name input field of the Inspection section.

The Code Inspector: Inspection screen is opened.
In the Object Selection section, enter the name of the Object Set you have just created or choose F4 to search for the relevant one.
In the Check Variant section, enter the name of the generated check variant or choose F4 to search for the relevant one.
To trigger creation of the inspection, save your input.

The inspection is saved.
Execute the inspection, for example, by pressing F8 for immediate execution..

Note
Depending on the number of objects in the object set, execution might take several hours. Therefore, consider starting the inspection in a job by pressing Shift + F1.

As soon as the inspection has been finished, the Results icon is displayed in the toolbar.
Choose the Results icon, to access the inspection findings.

Results

As soon as you have successfully performed the Code Inspector, the Code Inspector: Results from screen is opened. It provides you with information as to what simplifications are needed and where, and also information as to the relevance of the simplifications that need to be adapted in your customer code.

Example

Figure 2: Example of an inspection result displayed on the Code Inspector: Results from screen

Here, the highlighted area indicates that the field length of the MATNR domain has been extended from 18 to 40 characters. In this case, you are trying to move a field with a new field length of 40 characters into a field with 18 characters. This needs to be checked and adapted. In addition, a SAP note is mentioned where you can find further information.

To investigate which findings are relevant and need to be adapted in your evaluation system, you can start to analyze the impact of your customer objects. You then know which simplifications need to be adapted in your customer objects and, afterward, you can start with the manual adaptation.
