How To Fix WT314 - Target stock calculated dynamically: target range of coverage must be > 0

SAP Error Message - Details

• Message type: E = Error

• Message class: WT - Retail: Replenishment

• Message number: 314

• Message text: Target stock calculated dynamically: target range of coverage must be > 0

What causes this issue?

The MRP type you used means that the target stock is calculated
dynamically based on forecast data. The target range of coverage has to
be greater than zero.

System Response

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

How to fix this error?

Maintain the target range of coverage or use a different MRP type.

• What is the cause and solution for SAP error message WT314 - Target stock calculated dynamically: target range of coverage must be > 0 ?

  Certainly! Here's a detailed explanation for the SAP error message WT314: "Target stock calculated dynamically: target range of coverage must be > 0":
  
  Error Message:
  WT314 - Target stock calculated dynamically: target range of coverage must be > 0
  
  Cause:
  This error occurs during the calculation of target stock in SAP's Warehouse Management (WM) or Inventory Management (IM) when the system tries to dynamically calculate the target stock based on a coverage period, but the target range of coverage (usually a time period like days or weeks) is set to zero or a negative value.
  In other words, the system expects a positive value for the coverage period to calculate how much stock should be kept as a target, but it finds zero or no value, which is invalid.
  
  Where it typically occurs:
  
  In Inventory Management or Warehouse Management when using dynamic target stock calculation.
  When setting up or running stock determination, replenishment, or planning processes that rely on coverage periods.
  During material master or storage location settings where target stock is calculated dynamically based on coverage days.
  
  
  Solution:
  
  
  Check the Target Range of Coverage Setting:
  
  Go to the relevant customizing or master data where the target stock coverage is defined.
  For example, in Material Master (MM), check the MRP parameters or WM storage bin settings where the coverage period is specified.
  Ensure that the target range of coverage (e.g., days of coverage) is set to a positive integer greater than zero.
  
  
  
  Adjust the Coverage Period:
  
  If the coverage period is zero or blank, enter a valid positive number.
  Typical values depend on business requirements but must be > 0.
  
  
  
  Check Customizing Settings:
  
  In SPRO under Warehouse Management or Inventory Management, verify the settings related to target stock calculation.
  For example, in WM, check the target stock calculation method and ensure the coverage period parameter is correctly maintained.
  
  
  
  Review User Exits or Enhancements:
  
  If there are any custom developments or user exits influencing target stock calculation, verify that they do not set the coverage period to zero or an invalid value.
  
  
  
  Re-run the Process:
  
  After correcting the coverage period, re-run the stock calculation or planning process.
  
  
  
  
  Additional Information:
  
  Target stock calculation is often based on historical consumption and coverage days to ensure sufficient stock is available.
  The coverage period represents how many days/weeks of stock should be maintained.
  A zero or negative coverage period logically means no stock is required, which conflicts with the dynamic calculation logic.
  This error helps prevent incorrect stock levels that could lead to stockouts or overstocking.
