SAP EWM Posting change is a change of product stock categories in EWM, such as unrestricted stock to blocked stock, or change in the product or batch number. It’s basically changing a stock type or batch or product in a Extended Warehouse Management (EWM) system.
The process of posting change varies based on their warehouse structure and rules. Some Warehouses allow stock type changes within the bin and some would like to physically move out products to other bin locations. Also considering where the posting change triggers, some businesses trigger request in ERP and some trigger directly in EWM. Where ever it triggers finally postings get updated both EWM and ERP. This blog posts will explain you how we can map Distribution centers posting change process in SAP EWM system.
SAP EWM posting change functionality is very flexible to map for business scenarios. The main controlling factor of posting change is in the warehouse process type settings. The warehouse process type will allow posting change with in a bin or other bin by creating WO where you pick and putaway product. For example if I need to change a product stock type or a batch with in a bin then I may use transaction code /N/SCWM/POST but if I need a physical movement of product change over then I need posting delivery document that may give Warehouse order for pick and pack & putaway product.
Typically, I may need two warehouse process types for one warehouse system. 1) Posting change with in a Bin 2) Posting change in a destination bin.
For both warehouse process types we need Whse process Category as “7 (Posting change)”.
A. SAP EWM Posting change with in a Bin:
Based on warehouse process type setting as shown below, the posting change can be posted directly during creation time and within the bin (no physical movement). Generally we can use this warehouse process type in the transaction of /N/SCWM/POST. This transaction will create and post the changes immediately with a WT(warehouse material document) category 7 and can be seen in the monitor.
B. SAP EWM Posting change in a destination bin:
Below shown warehouse process type setting with indicator “2” as post change in bin. This means the posting change can be created with a warehouse task/ Warehouse order and product should goes to a destination bin. Generally we use this warehouse process type during posting change delivery (a warehouse request document and a sub sequence warehouse task).
Posting change created in EWM:
You can create a posting change directly in SAP EWM by using transaction code /N/SCWM/POST or create a posting change delivery document from transaction /N/SCWM/IM_PC and once posted finally goods movement communicated to SAP ERP.
Posting change created in ERP:
Posting change originates in ERP system from MB1B or MIGO transaction. Once posted in ERP causes an outbound delivery document created and distributed to EWM system as a warehouse request document.
SAP EWM Posting change delivery example scenario:
Now we look into a complete design of posting change process for product change from Article A to Article B by picking, packing and putaway steps. Warehouse staff needs to physically pick the Articles into HU and labeling the new article bar code and putaway back in the bin.
First, we create a standard material document posting with MB1B of movement type 309 that creates a standard outbound delivery and distribute to EWM system.
I would like to break the total configurations into five parts.
- Configurations related to Posting Change Delivery Document
- Configurations related to Warehouse process type and Work Center Storage type
- Configurations related to Storage Control setup for pick pack and putaway process
- Configurations related to Strategies- search sequence for stock removal and putaway
- Configurations related to WOCR, Activity area and Master data setup
Now we go though each and every area to setup the process
1. Configurations related to Posting Change Delivery Document
SPRO/ Extended Warehouse Management/ Internal Warehouse Processes/ Delivery Processing / Posting Changes/ Manual Settings/ Define Document Types for Posting Change Process
Document type ZTRP is copied from standard TWPR document types
SPRO/ Extended Warehouse Management/ Internal Warehouse Processes/ Delivery Processing / Posting Changes/ Manual Settings/ Define Item Types for Posting Change Process
Item types ZTRP are copied from standard TWPR item types
SPRO/ Extended Warehouse Management/ Interfaces/ ERP Integration/ Delivery Processing/ Map Document Types from ERP System to EWM
DTR document type in ECC is mapped to ZTRP doc type
2. Configurations related to Warehouse process type and Work Center Storage type
SPRO/ Extended Warehouse Management/ Cross-Process Settings/ Warehouse Task/ Define Warehouse Process Type
Warehouse process type ZTRP with Category 7 for posting change, Activity ZTRP
SPRO/ Extended Warehouse Management/ Cross-Process Settings/ Warehouse Task/ Determine Warehouse Process Type
ZTRP document type is assigned to ZTRP process type
SPRO/ Extended Warehouse Management / Master Data / Define Storage Type
IMPC storage type is configured as a work center storage type for posting changes
HU requirement is selected on for this storage type since stock should only be placed there in an HU during the changeover processing to the work center
The availability group DOC is used as mandatory to ensure that changed over stock will be F1 stock type (ROD (received on Dock-goods in putaway in ECC). This is to keep the stock as not-available-for-sale until it is put away.
SPRO/ Extended Warehouse Management / Master Data / Define Work Center
3. Configurations related to Storage Control setup for pick pack and putaway process
SPRO/ Extended Warehouse Management/ Cross-Process Settings/ Warehouse Task/ Process-Oriented Storage Control – External Storage Process Step
External step ZTRP is defined as picking category.
SPRO/ Extended Warehouse Management/ Cross-Process Settings/ Warehouse Task/ Process-Oriented Storage Control – Process-Oriented Storage Control
The external step PTWY and the source bins for IMPC assigned to the necessary putaway warehouse process types PTWY.
SPRO/ Extended Warehouse Management/ Cross-Process Settings/ Warehouse Task/ Process-Oriented Storage Control – Storage Process Definition
The storage process IMPC is defined as Internal Movement.
SPRO/ Extended Warehouse Management/ Cross-Process Settings/ Warehouse Task/ Process-Oriented Storage Control – Assign Storage Process Step
The storage process IMPC is assigned the 3 steps of ZTRP (Pick), PACK, and PTWY.
4. Configurations related to Strategies- search sequence for stock removal and putaway
/SPRO/ Extended Warehouse Management/ Goods Receipt Process/ Strategies/ Storage Type Search/ Specify Storage Type Search Sequence for Putaway
/SPRO/ Extended Warehouse Management/ Goods Issue Process / Strategies/ Determine Storage Type Search Sequence for Stock Removal
5. Configurations related to WOCR, Activity area and Master data setup
SPRO/ Extended Warehouse Management/ Cross-Process Settings/ Warehouse Order/ Define Packing Profile for Warehouse Order Creation
SPRO/ Extended Warehouse Management/ Cross-Process Settings/ Warehouse Order/ Define Creation Rule for Warehouse Orders
SPRO/ Extended Warehouse Management/ Cross-Process Settings/ Warehouse Order/ Define Search Sequence of Creation Rules for Activity Areas
Master data activities
Transaction /SCWM/SBST (or /SCWM/SRTUP)
Transaction /SAPCND/GCM – Condition Maintenance
Add the BULK packing profile if missing in application and maintenance group PAK for 0BDL condition type
Finally you would able to see the Posting change delivery process with warehouse process type ZTRP configured for post change in putwaay bin had WT’s created as shown below
Also see below posting change with a process type that had post change “POST” with in a bin had only material posting change WT
