Guide to Transaction Code MMBE in SAP
The SAP MMBE transaction code is a powerful tool used
in inventory management for displaying stock overview. It gives detailed
visibility into the stock situation across different organizational levels
such as Company Code, Plant, and Storage Location.
Understanding Key Fields in MMBE
Unrestricted Use Stock
Unrestricted use stock refers to materials that are readily
available for use in production or to fulfill customer orders. These are
not blocked, under inspection, or reserved in any way.
-
Implications at Company Code Level: Reflects the total
quantity of stock available across all plants.
-
At Plant Level: Shows the stock available within a
specific plant.
-
At Storage Location Level: Gives a granular view of
available inventory at each physical storage location.
Note: Discrepancies between these levels could indicate
stock in transit, pending inspections, or reservations that haven't been
updated.
Open Order Quantity
This field indicates the quantity of stock that is scheduled
to arrive based on outstanding purchase orders. It helps procurement
and warehouse teams anticipate incoming goods and plan accordingly.
Receipt Reservations
Receipt reservations represent confirmed reservations
in the system. These are stock allocations made in advance for internal
consumption or production needs.
-
Ensures materials are set aside for specific needs.
-
Prevents stock from being accidentally issued elsewhere.
Stock Request
Stock requests consolidate open orders and deliveries and
offer the functionality to drill down into transactional details
for each item.
Reservations (as Part of LR Process)
This refers to non-procurement reservations, part
of the Logistics Requirements (LR) planning. These are memorandums used
to record internal material demands without generating a purchase document.
Company-Owned Special Stocks
These are materials owned by your company but stored at
an external location, such as a vendor or customer premises. Since
they are outside your direct control:
-
Managed at Plant Level only
-
Not assigned to a specific storage location
-
Can be classified as:
-
Unrestricted-use stock
-
Quality inspection stock
-
Cannot be marked as blocked stock.
Types in SAP:
-
Stock of Material Provided to Vendor: Sent to vendor
for subcontracting or processing.
-
Consignment Stock at Customer: Remains your property
until used by the customer.
-
Returnable Packaging Stock at Customer: Pallets or
containers delivered to customers but still owned by your company.
Externally-Owned Special Stocks
These are materials owned by vendors or customers but
stored at your facility. They're more tightly controlled and tracked.
-
Managed at Storage Location Level
-
Can be categorized as:
-
Unrestricted-use
-
Quality inspection
-
Blocked stock
Types in SAP:
-
Vendor Consignment: Stock supplied by vendors and
used as needed, payment only made after use.
-
Returnable Transport Packaging (RTP): Reusable containers
or pallets.
-
Sales Order Stock: Stock tied to a specific customer
order.
-
Project Stock: Reserved for specific internal or customer
projects.
Returnable Transport Packaging (RTP)
RTP refers to multi-trip packaging items like containers
or pallets that are returned after use.
-
Owned by Vendor
-
Classified only as Unrestricted-use stock
-
Cannot be put under quality inspection or blocked statuses.
-
Helps reduce packaging waste and cost.
Material Movements in MMBE
This view showcases the transaction history of a material,
providing:
-
Detailed records of stock in/out movements
-
Ability to sort by columns like movement type, date, or quantity
-
Customizable views for better insight and traceability
Frequently Asked Questions (FAQs)
1. What is MMBE used for in SAP?
MMBE displays stock overview at various organizational levels,
providing detailed information on inventory status across locations.
2. How is unrestricted-use stock different from blocked stock?
Unrestricted-use stock is available for immediate use, while
blocked stock is not usable due to quality issues, audits, or system holds.
3. Why are Company-Owned Special Stocks not managed at the
storage location level?
Because these stocks are not physically present in your warehouse,
they are only tracked at the plant level.
4. Can returnable transport packaging be blocked?
No, RTP is always classified as unrestricted-use stock and
cannot be placed under inspection or blocked.
5. What is the difference between reservation and stock request?
Reservations are pre-booked internal requirements, while
stock requests include all open demands and can be analyzed further.
6. How does SAP differentiate between vendor consignment
and project stock?
Vendor consignment is owned by the vendor and used on demand,
while project stock is company-owned but reserved for a specific project. |
