How To Fix WSTI_CALC066 - Item written off but recalculation would result in a different book inv.

SAP Error Message - Details

• Message type: E = Error

• Message class: WSTI_CALC - Physical Inventory Messages: Book Inv. Calc. at Count Time

• Message number: 066

• Message text: Item written off but recalculation would result in a different book inv.

What causes this issue?

The book inventory for the count time has been calculated for this item.
The item has a book inventory of &V1& &V2&. However, if you were to
repeat calculation of the book inventory for the count time for this
item, this would mean &V3& &V2& the quantity of relevant POS
transactions would change. However, since the difference has already
been written off, which means that physical inventory is completed, no
further changes can be made to the item.

System Response

The system displays this message as the result of an analysis when the
POS transactions are displayed for the inventory document.

How to fix this error?

Check why the quantity of relevant POS transactions for this item in the
inventory document has changed. This might, for example, be for one of
the following reasons:
The book inventory for the count time was calculated for this inventory
document and the inventory differences were then written off. Further
POS transactions, which are relevant for calculating the book inventory
because they are in the corresponding period, were then transferred from
your POS system to the ERP system.
In this case, an error has occurred and can only be corrected by
repeating physical inventory for the material. In the future, make sure
that all the relevant POS transactions are transferred to the ERP system
before you calculate the book inventory.
The book inventory for the count time was calculated for this inventory
document and the inventory differences were then written off. The
relevant POS transactions were then reorganized.
In this case, the book inventory for the count time is correct but the
list of POS transactions displayed in the overview may be incomplete.

Procedure for System Administrators

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

• What is the cause and solution for SAP error message WSTI_CALC066 - Item written off but recalculation would result in a different book inv. ?

  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  WSTI_CALC066
  
  Text: Item written off but recalculation would result in a different book inventory.
  
  Cause:
  This error occurs during the inventory valuation or goods movement process when an item has been written off (e.g., due to scrapping or loss), but the system detects that if it recalculates the inventory value or quantity, the resulting book inventory (stock quantity or value) would differ from what is currently recorded.
  In other words, the system is trying to ensure consistency between the physical stock, the book inventory, and the valuation. If an item is written off, the system expects the recalculation to confirm the book inventory. If it doesn't, it raises this error to prevent inconsistencies in inventory valuation.
  Common scenarios causing this error include:
  
  Manual adjustments or postings that cause discrepancies between physical stock and book inventory.
  Incorrect or incomplete movement types or valuation class assignments.
  Issues in the material master data, such as incorrect valuation settings.
  Problems during inventory closing or period-end closing where recalculation is triggered.
  Partial write-offs or scrapping where the system expects the recalculation to match the written-off quantity/value.
  
  
  Solution:
  To resolve this error, consider the following steps:
  
  
  Check Material Master Data:
  
  Verify the valuation class, price control (standard price or moving average price), and other valuation-related settings.
  Ensure that the material master data is consistent and correctly maintained.
  
  
  
  Review Inventory and Stock Data:
  
  Check the stock quantities and values in the system (using transactions like MMBE, MB52).
  Compare physical stock with book inventory to identify discrepancies.
  
  
  
  Analyze Movement Types and Postings:
  
  Review the movement types used for the write-off or scrapping.
  Ensure that the postings are correctly done and consistent with valuation.
  
  
  
  Run Inventory Recalculation or Adjustment:
  
  Use transaction MIRO or MBRL (for scrapping) carefully.
  If discrepancies exist, perform inventory adjustments or revaluation to align book inventory with physical stock.
  
  
  
  Check for Open or Incomplete Documents:
  
  Sometimes open or incomplete material documents can cause recalculation errors.
  Clear or complete these documents.
  
  
  
  Consult SAP Notes and Support:
