# Increased maximum size for Mappings documents

> Mappings: Increased maximum document size

Published Feb 10, 2022

Product: EDI platform

To support developers working with larger JSON documents, we have increased the maximum mapped document size from 1 megabyte to 4 megabytes in order to accommodate a wider range of use cases.

**New \$currentDateTime function in Mappings**

You can now use \$currentDateTime function to generate current date and time in different formats and timezones. For example, if you want to generate a current date in an EDI format, you can achieve this by \$currentDateTime(\$dateTime.EDIDate). If you need to have it generated for a different timezone, you can do so by specifying the 2nd argument like so: \$currentDateTime(\$dateTime.EDIDate, "Europe/Berlin").
