Symptoms

Custom report displays a blank page when it runs from the A&M Console.

Cause

The report is designed incorrectly.

Resolution

Please revise the report design. If the custom report displays a blank page when it runs from the A&M Console, please re-check it in the IDE (MS Report Builder, Visual Studio, etc) and with high probability the result will be the same. 

If empty data is gotten by SQL query or Stored Procedure, the report will show a report header. 

Check matching of parameters data type with their real definition in ABBYY Database.

This particular example shows mismatch of the parameter which is assigned to a field "BatchId":

1. BatchId which is an integer in database schema: ​

2. But in the report builder parameter is declared as a string. 
​​

When this discrepancy is fixed, the report is showing the data correctly.
