Discover SAP EWM MFS
Deep-dive Layout-oriented Storage ControlThis blog is part of the series ‘SAP EWM meets Automation – Discover EWM MFS’ and ventures to deep-dive into the usage of the layout-oriented storage control (LOSC) in the context of MFS processes. We will assume that we are in a MFS-environment, moving a HU across MFS-relevant storage bins (~ communication points). To be more specific, we will look at an HU moving across a conveyor:
FM /SCWM/TROUTL_DET is the most important one in this context here. So let us have a look at it step-by-step!
1. Read the LOSC customizing
Right at the beginning we read the routing records from the customizing:
2. Fire selects onto the customizing table in order to find a valid record
We have a hard-coded access sequence here (unlike e.g. queue determination or STSS where we have an option to customize the access sequence). This is very important in order to understand which record is selected for routing (keeping a screenshot of this access table is a life hack for every EWM consultant ):
.Note that EWM standard will always apply the matching record on sequence number #1. We will come back to the usage of the other records later, when we look at options for enhancements (Prio BAdi).
3. Capacity check
Note: Have a look at this blog post in case you want to make yourself familiar with important MFS objects (like the communication point).
