Transfer Posting between Stock Types in SAP MM | Unrestr. Use | Quality Inspection | Blocked Stock

Main ideas & lessons from the video

• Purpose of the lesson: Demonstrates transfer postings between different SAP MM stock types—specifically:
  • Unrestricted use stock
  • Quality inspection stock
  • Blocked stock
• Key distinction in SAP:
  • Stock transfer (physically moving inventory): Physical movement is mandatory (e.g., storage location/warehouse/plant/company code changes).
  • Transfer posting (changing stock identification/type): Physical movement is optional; the posting primarily changes the stock type/material identification in SAP.
• Practical scenario used throughout:
  • Receives material into all three stock types.
  • Then performs a sequence of movement types to move stock between types and shows how SAP enforces consumption rules.

Concepts explained

1) What is a stock transfer / transfer posting?

Organizations may need to:

• Move inventory between locations/warehouses, or
• Change the identification/availability status of material in SAP.

Examples given:

• Quality inspection flow: vendor receipt → mark as Quality Inspection → once accepted → change to Unrestricted Use
• Blocked flow: damaged/expired stock → mark as Blocked → prevents usage

2) Definitions of the three stock types

• Unrestricted use
  • Can be withdrawn for consumption/production
  • Allowed for “issue/consumption” movement type 201 (as demonstrated)
• Quality inspection
  • Not withdrawable for consumption
  • Represents stock pending quality checks
• Blocked stock
  • Not withdrawable for consumption
  • Represents stock that is unusable (e.g., damaged/expired) and not under quality inspection

3) Rule enforced by SAP for consumption

Goods Issue for consumption (movement type 201):

• Cannot be posted against Quality Inspection or Blocked stock
• Requires stock in Unrestricted Use
• If unrestricted stock is missing, SAP throws a deficit error

Methodology / step-by-step workflow (as shown)

A) Create PO and receive material into all three stock types (setup)

• Create Purchase Order

  • Transaction: ME21N
  • Example material: coffee, quantity 15 kg
  • Note: PO line has a stock type field (default often Unrestricted Use)

• Post Goods Receipt (GR) into multiple stock types

  • Transaction: MIGO
  • Choose Goods Receipt for the PO
  • Split receipt quantity into 3 lines using Distribute Quantity:
    • 5 kg → Unrestricted Use
    • 5 kg → Quality Inspection
    • 5 kg → Blocked Stock
  • Set/confirm storage locations as needed

• Verify stock

  • Transaction: MMBE (Stock Overview)
  • Confirm:
    • 5 kg Unrestricted
    • 5 kg Quality Inspection
    • 5 kg Blocked

B) Transfer posting: Quality Inspection → Unrestricted Use

• Movement type used: 321 Description shown: “Transfer quality to unrestricted”

• Steps:

  • Transaction: MIGO
  • Select Transfer posting
  • Movement type: 321
  • Enter:
    • material, plant, storage location, destination storage location (optional)
    • quantity
  • Post
• Verification:
  • After posting, MMBE shows:
    • Quality Inspection reduced (5 kg transferred out)
    • Unrestricted increased accordingly

C) Transfer posting: Blocked Stock → Unrestricted Use

• Movement type used: 343 Description shown: “Transfer from block to unrestricted”

• Steps:

  • Transaction: MIGO
  • Transfer posting
  • Movement type: 343
  • Enter material/plant/storage location and quantity
  • Post
• Verification:
  • Blocked becomes nil
  • Unrestricted increases (reflects transferred quantity)
• Accounting impact check:
  • Transfer postings do not create financial (FI) postings
  • Evidence: documents show “no subsequent document found in accounting.”

D) Reverse Quality Inspection → Unrestricted Use (i.e., Unrestricted → Quality Inspection)

• Reversal movement type used: 322 Reversal of 321

• Steps:

  • Transaction: MIGO
  • Transfer posting
  • Movement type: 322
  • Enter material/plant/storage location/quantity (example shown: 10 kg)
  • Post
• Verification:
  • Stock shifts from Unrestricted back to Quality Inspection

E) Reverse Blocked Stock → Unrestricted Use (i.e., Unrestricted → Blocked)

• Reversal movement type used: 344 Reversal of 343

• Steps:

  • Transaction: MIGO
  • Transfer posting
  • Movement type: 344
  • Enter details and quantity (example shown: 5 kg)
  • Post
• Verification:
  • Unrestricted reduced
  • Blocked increased

F) Move Blocked → Quality Inspection

• Movement type used: 349 Description shown: “Transfer block to QI”

• Steps:

  • Transaction: MIGO
  • Transfer posting
  • Movement type: 349
  • Enter details and quantity
  • Post
• Verification:
  • Blocked decreases
  • Quality Inspection increases

G) Move Quality Inspection → Blocked (reverse of 349)

• Reversal movement type used: 350 Reversal of 349

• Steps:

  • Transaction: MIGO
  • Transfer posting
  • Movement type: 350
  • Enter details and quantity
  • Post
• Verification:
  • Quality Inspection decreases
  • Blocked increases

H) Test consumption restriction using Goods Issue (movement type 201)

• Transaction: MIGO
• Choose Goods Issue (consumption)
• Movement type: 201
• Attempts:
  1. Try issuing from Quality Inspection stock
     • SAP error: stock type not allowed for movement type 201
  2. Try issuing from Blocked stock
     • Same kind of error
  3. Try issuing from Unrestricted Use
     • SAP allows only if unrestricted stock exists; otherwise deficit error occurs
• Conclusion:
  • Consumption is only possible from Unrestricted Use stock

I) Review material movements history

• Transaction: MB51
• Shows each movement with:
  • Negative quantity in the “from” stock type
  • Positive quantity in the “to” stock type
• Confirms sequence:
  • GR into 3 stock types
  • Transfer postings using 321 / 343
  • Reversals using 322 / 344
  • Block/QI flow using 349 / 350

Movement types emphasized (must-remember mapping)

• 321 = Quality Inspection → Unrestricted Use
• 322 = Reverse of 321 = Unrestricted Use → Quality Inspection
• 343 = Blocked → Unrestricted Use
• 344 = Reverse of 343 = Unrestricted Use → Blocked
• 349 = Blocked → Quality Inspection
• 350 = Reverse of 349 = Quality Inspection → Blocked

The video’s teaching shortcut: remember the “base” ones (321, 343, 349); reversals are the base + 1.
