This is the translated and rendered full reply from the Joule Studio test. The original answer was in German. I translated it into English for the blog post, but kept the structure and content of the answer.

Evidence Table: Verified Technical Dependencies
| Category | Object | Usage | Clean Core Status | Risk Rating |
|---|---|---|---|---|
| Direct SAP tables | ||||
| USR02 | User master | SELECT SINGLE on BNAME, GLTGV, GLTGB in get_user_validity() | Not compliant | High |
| BUT000 | Business Partner | SELECT SINGLE on PARTNER in partner_exists() | Not compliant | High |
| Data types | ||||
| XUBNAME | User name | Parameter for get_user_validity() | Standard | Low |
| BU_PARTNER | Partner ID | Parameter for partner_exists() | Standard | Low |
| ABAP_BOOL | Boolean | Return value of both methods | Compliant | Low |
| System fields | ||||
| SY-DATUM | System date | Date comparison in get_user_validity() | Standard | Low |
| SY-SUBRC | Return code | Existence check in both methods | Standard | Low |
| Recommended APIs | ||||
| CL_IDENTITY_SU01 | User details | Replacement for USR02 access | Released | n/a |
| IF_USER_MANAGEMENT | User management | Alternative for user validation | Released | n/a |
| CL_MD_BP_MAINTAIN | BP management | Replacement for BUT000 access | Released | n/a |
| IF_BUPA_CONSTANTS | BP constants | Alternative for partner existence check | Released | n/a |
Transport and Package Context
Note: Due to system access issues, transport and package information could not be retrieved directly. Based on the naming convention (ZCL_ARC1_*), the class is probably:
- Package: likely Z namespace (customer-specific)
- Transport status: development object
- Dependencies: no direct custom callers identified
Clean Core Compliance Summary
| Assessment Criterion | Status | Recommendation |
|---|---|---|
| Direct DB access | 2 critical violations | Immediate migration to released APIs |
| API usage | No released APIs | Implement the recommended alternatives |
| Future readiness | At risk | High priority for modernization |
| Migration complexity | Medium | Clear functional boundaries make refactoring easier |
Recommendations
Immediate actions:
- Identify all callers of ZCL_ARC1_DEMO_CCORE
- Assess the business criticality
Migration to Clean Core:
- Replace USR02 access with CL_IDENTITY_SU01 or IF_USER_MANAGEMENT
- Replace BUT000 access with CL_MD_BP_MAINTAIN or IF_BUPA_CONSTANTS
- Implement unit tests to preserve behavior
Risk reduction:
- Use wrapper classes for a smoother migration
- Document the migration paths
- Integrate the object into the Clean Core roadmap
