Hi all,In Acumatica Accounts Receivable → Print Statements processing screen, the system is not processing when a large number of records are selected using the Process or Process All buttons and throwing the attached error. This issue occurs specifically in the Modern UI.I attempted the following troubleshooting steps in my dev environment, but the issue still persists: Modified the maxAllowedContentLength and maxRequestLength properties in the Web.config file Modified the Maximum Query Length setting at the IIS level Any input to help identify the root cause and suggest a solution or recommended configuration to handle large record processing in the Modern UI? Thanks in advance! Premalatha N

@premalathan35Please make following changes on web config only and that should fix the issue:<httpRuntime executionTimeout="300" requestValidationMode="2.0" maxRequestLength="1048576" enableVersionHeader="false" relaxedUrlToFileSystemMapping="true" maxqueryStringLength="8192" /><requestLimits maxAllowedContentLength="1073741824" maxurl="8192" maxqueryString="8192" />

Hi all,

In Acumatica Accounts Receivable → Print Statements processing screen, the system is not processing when a large number of records are selected using the Process or Process All buttons and throwing the attached error. This issue occurs specifically in the Modern UI.

I attempted the following troubleshooting steps in my dev environment, but the issue still persists:

Modified the maxAllowedContentLength and maxRequestLength properties in the Web.config file
Modified the Maximum Query Length setting at the IIS level

Any input to help identify the root cause and suggest a solution or recommended configuration to handle large record processing in the Modern UI?

Thanks in advance!

This is a known limitation/behavior of the Modern UI when handling large datasets, rather than a configuration issue.

@hkabiri , It is giving me an error with invalid syntax.

I believe this is a similar scenario where, when the number of customizations becomes large, the site encounters issues. In the same way, the Modern UI appears to exhibit issues when the count exceeds 50.
