SSRS reports are widely used in iMIS to deliver operational insights, financial summaries, committee data, event analytics, and membership intelligence.
However, as organizations migrate to iMIS EMS or enhance their reporting libraries, several recurring issues can arise—ranging from connection failures to rendering problems like iterating blank pages. This guide consolidates the most common SSRS issues in iMIS along with practical, field-tested solutions, based on real client work and migration experiences.
Connection Issues After Migrating to iMIS EMS
When reports are migrated into EMS, they often remain linked to the old database or production server, old data sources causing the report to fail or return no results. Before anything else: ensure that your report is pointing to the correct data source. In iMIS (especially after migration to EMS), many failures come from the report still referencing the old database/server.
- Open the Data Source Properties and verify server, database, and credentials.
- Use an embedded connection if needed and click Test Connection.
- Open each dataset and run the SQL or stored procedure directly.
- Confirm it returns rows and the expected columns.
- Check that all fields the report uses (tablix columns, textboxes, parameters) exist in the dataset.
- Remove or update references to obsolete tables or schemas.
Reports That Work in Report Builder but Fail in iMIS
Some reports fail showing a red dot while upload even after fixing connection strings and datasets. In such cases, a validated workaround within EMS is to copy an existing RDL inside the folder and overwrite it with the new RDL.
- Instead of uploading a fresh RDL, copy an existing working report in the same folder.
- Edit the copy and replace its RDL content with your updated report.
- Rename the copied report to your desired name and save.
- This preserves folder-level settings and hidden metadata that a new upload may not inherit.
Iterating Blank Page After Results (Common Rendering Issue)
This is one of the most frequent issues from clients—even when data looks perfect.
Root Cause: Extra blank pages in preview or PDF.
SSRS uses a fixed rendering rule based on physical report width.
A blank page generates when:
(Report Body Width + Left Margin + Right Margin) > Page Width
- Check the report body width, margins, headers, and footers.
- Ensure body width + left/right margins is not greater than the page width.
- Resize tablixes, textboxes, and other elements that extend past the right edge.
- Remove or adjust hidden containers that may push the layout wider than expected.
- Test exports (e.g., PDF) to confirm that page breaks and formatting are clean.
Confirm Mapped Tables
After migration (for example, from legacy iMIS to EMS), table and schema names often change. Reports may still reference older objects and fail or show incorrect data.
- Compare the dataset SQL to the current EMS database schema.
- Update old table names or schema prefixes to the new equivalents.
- Use any table mapping documentation (old → new) to systematically update reports.
- Re-run the dataset after updates to confirm success.
Conclusion..
By following these steps in order—checking the connection, validating datasets, confirming mapped tables, fixing layout issues, and applying EMS-specific workarounds—you can quickly isolate and resolve most SSRS issues in iMIS. This structured approach helps reduce reporting downtime and ensures consistent, accurate reports for your organization.
