ML_Not Distributed Line in ML analysis


  1. Not distributed Line Item in ML analysis (CKM3)
PVTDJ3E75EN5

**'Not distributed' price differences can be due to four reasons:
A) System applied a 'Price limiter' logic (stock coverage check).
You can analyze this case using the value flow monitor transaction:
- for release 4.7 , transaction CKMVFM
- for release 4.6C, program SAPRCKM_VERIFY_PRICE_DET (note 324754 is required).
- for release < 4.6C: Program ZVERIFY_PRICE_DET (included in the note 324754) Or directly checking the field CKMLPP-PBPOPO manually.
In this case the value CKMLPP-PBPOPO is bigger than cumulative inventory.
If you still want these price differences to be distributed, you can switch off price limiter logic. Then all price differences are posted to stock, and the price difference account is cleared. You should decide for each material if you want to switch off price limiter logic or not. So you can achieve a compromise between realistic prices and clearing the balance of the price different account.
Price limiter logic can be switched off in the following way:
* Resetting the price limiter quantity
In release 4.7 this is done using transaction CKMVFM.
In release <= 46C using the program ZREMOVE_PRICE_LIMITER (see note 325406).
* Note 855387: Application of this note will create an additional selection parameter for step 'Single Level Price Determination' to switch on/off price limiter logic.
This option is the better way, as it simplifies the process and provides more flexibility (see the note for more information).



B) System applied a fallback strategy during price determination (see note 579216) to avoid a negative periodic unit price (PUP).
Please check the attached note 579216: If the regularly calculated PUP (based on 'Cumulative Inventory' line) would become negative, the system uses a different strategy to calculate the PUP:
The PUP is calculated with these priorities:
1. 'Cumulative Inventory' line (no fallback)
2. Receipts ('ZU') line (Info message C+ 135 in the log)
3. Beginning inventory ('AB') line (Info message C+ 138 in the log)
4. PUP-price of previous period (Info message C+ 136 in the log)
5. S-price (Info message C+ 137 in the log).
The fallback strategy is active by default for Single-Level price determination.
For multilevel price determination it must be activated with parameter 'Negative price: automatic error management'.
As a solution, you might check the postings of these materials if they really need to have such big negative price differences or if there is some kind of error in the posting or the production structure
If you find such errors, you might reverse the corresponding postings and post them in a correct way.
Or, you might use transaction MR22 (debit/credit material) in order to post an appropriate positive amount of differences to the concerned materials so that the resulting actual price would no longer be negative. This allows performing the period closing regularly. In the next period, you might remove this manual posted value from the materials (again with MR22) in order to correct the overall stock values back to their original amounts.



C) Execution of transaction CKMM.
The above situation may be produced because transaction CKMM was executed during the corresponding period.
When transaction CKMM is processed the system deletes the price differences for the material in the period and these differences are not longer in the period record tables.
See note 384553 for further details.
The fact is that the price differences are still visible in CKM3 (as not distributed). This is due to the missing reset of summarization records (MLCD).
This error is just a problem of CKM3 display, because the differences shown as 'not distributed' do not exist in the periodic records. The PUP of the material is calculated correctly.
The error is solved with note 838989:


D) A subsequent price change (LTPC).
In transaction CKM3 when a subsequent price change (LTPC) is carried out, the preliminary valuation and all differences are rescaled at category level. Additionally, the corresponding lines for price change documents are sorted and flagged with the text "Subsequent price change".
If a late price change is run with transaction MR21 and there were not a previous reversal of the consumptions already posted in the period, these documents cannot be rescaled by transaction MR21.
Therefore transaction CKM3 will show a "Not distributed line" although the PRDs are rescaled correctly. This is then a display side-effect in CKM3.
