2953261 - Error Rendering List Component for a Specific user due to "SQL statement is too long" - Report-Canvas / Advanced Reporting

• A user which has all the required permissions to run a Canvas - Advanced Reporting query gets an "Error rendering list report component" message.
• The report may fail when previewed or executed Online.
• The report may fail when executed or downloaded Offline.
• The report may run successfully Online but fail Offline, or vice versa.
• The same report runs successfully for some users (for example, Admin users) but fails for specific users.
• In the backend, support can observe the following error log: "SQL statement is too long"

SAP SuccessFactors HCM Suite

1. Navigate to Report Center.
2. Open a Canvas (Advanced Reporting) report.
3. Attempt to:
   1. Preview the report, or
   2. Run the report Online, or
   3. Run the report Offline and download the output.
4. Observe the execution or rendering error.

The issue occurs when the SQL statement generated at runtime exceeds backend technical limits for a specific execution context. This can be caused by one or more of the following factors:

Report Complexity

• Large number of selected objects and joins
• Many selected fields
• Calculated columns
• Aggregated Calculated Columns
• Complex filters
• Large data volumes

RBP Role and Target Population Complexity

• Multiple permission roles assigned to the user
• Overlapping roles granting the same entities or reports
• Different target populations that must be evaluated simultaneously
• Each role and target population increases the complexity of runtime SQL generation.

Missing Field-Level Permissions (User-Specific)

• If a user lacks permission for one or more fields used in the Canvas report, the system generates additional metadata and permission-handling logic.
• This additional processing increases SQL complexity.
• As a result, a user with restricted field permissions may encounter SQL length or rendering errors, while another user with full permissions can successfully run the same report.

NOTE: Canvas reports are built on a legacy reporting framework in SAP SuccessFactors. Although the report definition remains the same, Online and Offline executions use different backend processing mechanisms, which can result in different execution outcomes. As a result, a Canvas report may run successfully in Online mode but fail in Offline execution, or vice versa.

The error “SQL statement is too long” indicates that, when the report is executed in the context of the affected user, the combined complexity of the Canvas report query and the user’s RBP target populations causes the backend system to generate an SQL statement that exceeds database limits. The following actions may help resolve the issue:

Option 1: Simplify the Report Query (Recommended)
Reduce the overall complexity of the Canvas report by optimizing its design:

• Remove objects that are not required
• Exclude fields that are not needed in the output
• Simplify filters and conditions
• Remove or reduce calculated columns and complex formulas

This approach reduces the size and complexity of the generated SQL statement and also improves overall report performance.
This option generally resolves the issue and is usually the easiest to apply.

Note: SAP Product Support cannot determine which elements of a customer report should be removed or optimized. Testing and validation must therefore be performed on the customer side.

Option 2: Simplify RBP Permissions and Target Populations
Reduce complexity in the user’s permission configuration:

• Review the number of permission roles assigned to the user
• Avoid assigning multiple roles that grant access to the same report - e.g.: if user has 2-3 roles granting a certain Report or Employee Central Effective Dated Entity Field that has different target populations, please consider reducing the number of roles.
• Where possible, consolidate or reduce overlapping roles

Each additional role and target population increases the amount of processing required before data can be returned, contributing to oversized SQL generation.
This option typically requires careful re‑evaluation of role design and may involve more effort, but it is sometimes necessary to sufficiently reduce complexity.

NOTES:

• Option #1 is typically sufficient and should be attempted first.
• Option #2 may be required when report optimization alone does not reduce SQL complexity enough.
• Canvas reports are based on a legacy reporting framework and do not include guardrails to prevent overly complex designs. As data volume and RBP configurations grow over time, reports may reach backend technical limits even without configuration changes.
• Report design and RBP configuration are customer‑managed settings and are outside the scope of SAP Product Support. If assistance is required to review or redesign the report or RBP configurations, please contact your SAP SuccessFactors implementation partner or SAP Professional Services.
