Configure the Maximum Requesting Entity Body Limit
Defining a value for the Maximum Requesting Entity Body Limit setting is optional.
You may need to set this value only if you use custom SQL scripts in advanced conditions and only if the scripts have more than 70,000 characters.
If you receive AJAX errors when saving your custom SQL scripts that have more than 70,000 characters, you can increase the value of the Maximum Requesting Entity Body Limit setting in the IIS. Increasing the setting ensures that the ASP can post that much data onto the server.
