• What is the cause and solution for SAP error message WT126 - No target stock determined (target range of coverage <= 0) ?

  Certainly! Here's a detailed explanation of the SAP error message WT126: No target stock determined (target range of coverage <= 0) including its cause, solution, and related information.
  
  SAP Error Message WT126: No target stock determined (target range of coverage <= 0)
  1. Cause
  The error message WT126 occurs during the calculation of the target stock in the Warehouse Management (WM) or Inventory Management (IM) module, often in the context of replenishment or planning processes.
  
  The system tries to determine the target stock based on the target range of coverage (also called target coverage period or target coverage days).
  The target range of coverage is either zero or negative, which means the system cannot calculate a meaningful target stock.
  This usually happens because the target range of coverage parameter is not maintained or incorrectly maintained in the material master or the planning parameters.
  It can also occur if the demand or consumption data used to calculate the target stock is missing or zero, leading to a zero or negative target stock.
  
  2. Where it occurs
  
  During stock determination or replenishment planning in WM or IM.
  When running stock transfer orders, replenishment orders, or planning runs.
  In processes involving target stock calculation based on consumption or forecast data.
  
  3. Solution
  To resolve the WT126 error, check and correct the following:
  a) Check Target Range of Coverage
  
  Go to the Material Master (transaction MM02) and check the MRP 2 view.
  Verify the Target Range of Coverage (field: Target coverage or Target coverage days).
  Ensure that this value is greater than zero.
  If it is zero or blank, enter a valid number representing the number of days of coverage you want to maintain as target stock.
  
  b) Check Planning Parameters
  
  If the target coverage is determined via planning parameters or custom settings, verify those settings.
  For example, in WM replenishment, check the replenishment parameters or customizing settings that influence target stock calculation.
  
  c) Check Consumption Data
  
  Ensure that the consumption or demand data used for calculating the target stock is available and valid.
  If consumption is zero or missing, the system cannot calculate a target stock.
  You may need to check historical consumption or forecast data.
  
  d) Review Customizing Settings
  
  In some cases, the error can be related to incorrect customizing in WM or IM.
  Check the settings for target stock determination in SPRO under:
  
  Logistics Execution ? Warehouse Management ? Strategies ? Define Target Stock
  Or under MRP settings if related to planning.
  
  
  
  e) Re-run the process
  
  After correcting the target coverage or consumption data, re-run the planning or replenishment process.
