What You’re Trying to Do (in simple terms)
You're uploading your inventory from a legacy system into SAP so that everything’s in place by November 1st go-live. You're using Movement Type 561, which is perfect, it’s designed for initial stock entries. But here's the twist: SAP treats materials differently depending on whether they are using Standard Price (S) or Moving Average Price (V). That affects how inventory values are calculated and what happens behind the scenes in accounting.Standard Price vs. Moving Average: What Really Happens
Standard Price (Price Control = ‘S’)
- SAP assumes you trust the standard price you’ve maintained in the material master.
- So whatever quantity you upload is multiplied by this standard price, that becomes your inventory value.
- If you enter a different price during the upload (batch input), SAP won’t silently accept it. Instead, it posts the difference to a price difference account.
If standard price = $10
You upload 100 units at $12 each → SAP will value at $10 x 100 = $1000
The $200 extra? → Goes to price difference account
Moving Average Price (Price Control = ‘V’)
- This is more flexible. SAP says, “Sure, I’ll take your value and adjust the MAP accordingly.”
- Whatever value you input in batch upload is used to calculate the new moving average.
If you upload 100 units for $1500 → SAP sets MAP = $15 BUT if you don’t enter any value, SAP just uses the current MAP in the material master, and MAP stays unchanged.
How to Actually Do the Upload
You’ll use transaction MB1C (or MIGO in newer SAP versions) with Movement Type 561. This is inventory without PO. Here's the workflow:Path in SAP GUI:
Logistics → Materials Management → Inventory Management → Goods Movement → Goods Receipt → OtherInput Fields:
| Field | Value |
|---|---|
| Document Date | Today’s date |
| Posting Date | Today’s date |
| Movement Type | 561 (defaulted) |
| Plant | e.g., 3000 |
| Storage Location | e.g., 0001 |
Then:
- Click on Movement type → Receipt → Initial Stock Entry (Own) → To Unrestricted
- Enter materials with Material Number and Quantity
- Press SAVE
Common Error: G/L Account Blocked
If you get an error like:“G/L account 399999 blocked for posting in company code 3000”, here’s the fix:
Fixing It:
1. Go to: Accounting → Financial Accounting → GL → Master Records → Individual Processing → CentrallyAlso check 79999 if you're uploading Finished Goods.
2. Enter:3. From the menu:
- G/L Account: 399999
- Company Code: 3000
- Choose GL account → Block
- Deselect all block boxes
- Save
Important: Do this in the master client, not a test or sandbox one.
Pro Tips
1. Double-check your price control (S or V) before uploading anything.
2. For MAP materials, enter a value in the batch input if you want the MAP to update.
3. For Standard Price materials, don’t bother inputting a value, it won’t change anything (but could cause GL difference postings).
4. Use LSMW or BAPI if you have hundreds or thousands of materials, easier than MB1C one-by-one.
5. After upload, reconcile inventory reports using MB52 and MM03.
TL;DR Cheat Sheet
| Scenario | Input Price in Upload? | Valuation Based On | Notes |
|---|---|---|---|
| Standard Price (S) | Optional (ignored) | Standard Price in master | Difference posted to price diff account |
| Moving Avg Price (V) | Yes (recommended) | Your input value | MAP will be recalculated |
