When packing handling units for shipping, or processing inbound handling units, it’s common to weigh them and post this value to SAP. We often see people manually entering weights into an entry screen.

Using our AdvancePack solution, desktop connected scales are used to read the weight of materials, handling units while packing, we can use the same tools in other areas in SAP. In this blog post, I’ll quickly show you how to use the standard SAP functionality to support a desktop-connected scale.

You’ll need:

  • Configuration access to your system.
  • Our ScaleConnect for SAP software for each desktop or a comparable third party scale integration application.

If you’re using our AdvancePack workstation, you already have the necessary configuration. As an overview, I’ll define a Packstation (WM) and WorkCenter (EWM).  The structure is usually defined as follows for WM and EWM environments:

SAP Packstation structure

I’ll describe the WM settings specifically, but the settings are basically the same in EWM except they are called WorkCenters instead of Packstations in EWM.

First, define a RFC connection to each Pack station scale and test the connection. (Note: standardized naming is important before starting, otherwise you’ll have a mess on your hands as you deploy more PCs and scales.) You’ll use the settings used in ScaleConnect. There are 2 separate settings here but the only one that matters is the Program ID.

In transaction HUPAST_C, for each pack station, refer to the RFC connection you created in the previous step.

And that’s it.

In AdvancePack, select the weight button or select F5 to refresh the weight on the screen.

In the standard SAP pack screen, select the “Weigh” button.

What happens in the background is that SAP makes an RFC call to the scale to read the weight.  The return value is read and imported into the screen.

I hope this information is helpful.
