When you import data into a data set, the maximum size of the import package is 100 MB by default. You can decrease this value to 1 MB or increase it up to 2047 MB.
Modify the size limit for data import in one of the following ways:
Ask a system administrator to change the following setting in the prconfig.xml file:
<env name="Initialization/MaximumFileUploadSizeMB" value="100" />, where value is the maximum size of the import package. The available range is from 1 to 2047.
Create an instance of the Dynamic System Setting rule that overrides the size limit in the prconfig.xml file:
Click Create > SysAdmin > Dynamic System Settings.
Enter a short description. For example, MaxImportSizeDataSet.
In the Owning Ruleset field, enter Pega-Engine.
In the Setting Purpose field, enter prconfig/Initialization/MaximumFileUploadSizeMB/default.
Click Create and open.
In the Value field, enter the maximum size of the package that can be imported. The available range is from 1 to 2047.
Click Save.
