# Functionality

The app relates to the standard SAP transactions:

<table><thead><tr><th width="319">SAP transaction</th><th>Description</th></tr></thead><tbody><tr><td>VL02N</td><td>Change outbound delivery for picking of inventory managed materials.</td></tr><tr><td>MIGO</td><td>Goods receipt of inventory managed materials; goods issue to cost centre or write off (scrapping); Transfer posting for storage location to storage location and stock status changes.</td></tr><tr><td>MI04</td><td>Enter inventory count (IM).</td></tr></tbody></table>

Standard SAP serial number procedures/usages are utilised by this app, so serial number functionality will perform in the same way as it does in the standard SAP transactions listed above. However, this app provides a serial number override configuration option that can influence SAP standard by changing the usage and/or existence required, so that the parent apps can operate differently to the Serial Number Profile settings that are assigned in the material master.
