SAP Digital Manufacturing Cloud is a manufacturing shop floor solution that supports production supervisors and workers during their daily work right on the shop floor where the products get manufactured. It is tightly integrated with SAP S/4 HANA or SAP ERP, where the production orders are plannedinventory is managed, and subsequent supply chain processes are triggered and processed.  

With an increasing demand for personalization and traceability of products, there is a clear trend towards lot-size one production One prerequisite for this is the capability to handle serial numbers throughout the value chain.  


In this blog, I will provide you with a step-by-step guide on how to configure SAP Digital Manufacturing Cloud to support serial number data collection during shop floor execution, including inventory updates in SAP S/4 HANA or SAP ERP. 

Note: The inventory needs to be set up with the serial number activated. 


  1. Set up the integration between SAP Digital Manufacturing Cloud integration and SAP ERP or SAP S/4HANA as described in theSAP Digital Manufacturing Cloud Integration Guide.  

  2. SAP ERP and SAP S/4HANA inventory managed with serial numbers is activated. 

  3. Transfer of Floor Stock Data is set up (see the SAP Digital Manufacturing Cloud Integration Guide - Transfer of Floor Stock Data).
    In the picture below, you can see the result of a successful Floor Stock Data Transfer.

Step-by-Step Guide

The configuration will enable the collection of the serial number during the assembly operation, including the update of the consumption with the serial number.  

Note: The production order, including Routing and BOM, is replicated from SAP ERP or SAP S/4HANA to SAP Digital Manufacturing Cloud. The serial number for the components is not included. 

The serial number will be visible on the physical component itself and during execution, this data needs to be collected to assign it to the finished product.  


Step 1: Create Custom Data Fields and Types in SAP Digital Manufacturing Cloud 

The custom data fields are used to store the ERP serial data and inventory information collected during assembly 

Create a Data Field

  • Open the Manage Data Fields app. 

  • Create a new data field. The name of the data field must be ERP_SERIAL_NUMBER. The type must be Text. This identifier is used to transfer the data back to ERP and to map it to the inventory. 


Create a new data type

  • Open the Manage Data Fields app. 

  • Create the new data type INV_SFC_SERIAL

  • Data Type: INV_SFC_SERIAL 

  • Make sure to collect the Category Assembly

  • Add the data fields: 

  • ERP_SERIAL_NUMBER which you have created in the previous step. 

  • INVENTORY_ID_SFC (this field is delivered as part of the standard delivery). 


Step 2: Enforce data collection on a specific material during assembly 

Attach the custom data type INV_SFC_SERIAL to the Build section of the material. With this configuration, you ensure that during assembly, this data is requested for collection for the specified material. 

  • Open your material in the Manage Material app.  

  • Go to the Build section. 

  • In the Data to Collect at Assembly drop-down box, select INV_SFC_SERIAL. 

  • Click on Save.


Manufacturing Execution

Data Collection during production 

  • Open one Production Operator Dashboard that has the Component Assembly Plugin configured, e.g. Default Workcenter PODDefault Operation POD. 

  • Select an SFC. 

  • Goto Activities. 

  • Goto Component List. 

  • Select Assemble for the component which has an external serial number. 

  • Assemble is opened and shows the data to be collected.

  • Open the F4 help for Inventory SFC and and select the inventory ID for your material.  

  • Enter the serial number: You can entered it manually or scan it from the physical product. 

  • Click Add to confirm assemblyThis triggers goods consumption, and a message is sent back to SAP S/4HANA or ERP to synchronize the stock. 

  • Synchronized Good Consumption with Serial Number with SAP ERP or SAP S/4HANA 

  • The information collected during assembly is automatically sent to SAP ERP or SAP S/4HANA. 

  • You can check the message flow in the Monitor Integration Messages app in SAP Digital Manufacturing Cloud. 

  • In SAP ERP and SAP S/4HANA, the corresponding material document is generated for inventory deduction. 



For the consumption of serialized component which is not produced in SAP Digital Manufacturing Cloud, data field 'ERP_SERIAL_NUMBER' need be configured.

  • Do configuration of integration between SAP Digital Manufacturing Cloud and SAP ERP or SAP S/4HANA on-premise system

  • Configure data field 'ERP_SERIAL_NUMBER' into the data type for assembly data collection of Material Master

  • Download serialized inventory from SAP ERP or SAP S/4HANA on-premise system to SAP Digital Manufacturing Cloud as floor stock

  • Assemble floor stock with Inventory ID and serial number collected in SAP Digital Manufacturing Cloud

  • The consumption of serialized component which is not produced in SAP Digital Manufacturing Cloud is synchronized to SAP ERP or SAP S/4HANA on-premise system automatically
