# Configuration

{% hint style="info" %}
**Note**

This configuration guide refers to PreBilt transactions beginning '*PB2\_*' and details the standard process without additional features or enhancements. You should [copy these transactions](/prebilt-for-im-wm-strm/configuration-guide/transaction-codes.md#create-a-transaction) with a different prefix to maintain a backup and protect the originals.

The guide displays the standard PreBilt screens and gives details of the structures in which the on screen fields can be found. Fields within these structures can be used to customise and enhance the screen. For instructions on how to use structures to find fields, please see [Available data structures](/prebilt-for-im-wm-strm/app-master-data/screen-framework/features/available-data-structures.md). For instructions on how to maintain the configuration elements in AMD, please see [General configuration elements](/prebilt-for-im-wm-strm/app-master-data/general-configuration-elements.md).
{% endhint %}

This configuration guide refers to transaction *PB2\_BARCODE\_DECODE*.

**Note**

As of release 5.8.0, you can add the SAP\_AI field into the decoder app transaction and thereby use the field to identify the barcode types that the particular SAP AI is included in for the barcode string just scanned.
