• Message number: 707

• Message text: Supply source determination only possible when redefining all master data

What causes this issue?

You have chosen to use supply source determination. However, you did
not choose to redetermine all master data. Redetermining all master
data is, however, a prerequisite of supply source determination.

System Response

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 WT707 - Supply source determination only possible when redefining all master data ?

  Certainly! Here's a detailed explanation for the SAP error message WT707: "Supply source determination only possible when redefining all master data":
  
  Error Message:
  WT707 - Supply source determination only possible when redefining all master data
  
  Cause:
  This error occurs during the Warehouse Task (WT) creation or processing in SAP Extended Warehouse Management (EWM) when the system tries to determine the supply source for a warehouse request or warehouse task, but the configuration or master data setup does not allow partial redefinition of master data.
  More specifically:
  
  The system is configured to redefine all master data (such as product master, storage bin master, source determination rules, etc.) during supply source determination.
  However, the current process or customization attempts to perform supply source determination without redefining all master data.
  This inconsistency leads to the error because the supply source determination logic requires a full redefinition of master data to work correctly.
  
  
  When does it typically occur?
  
  During supply source determination in warehouse processes like stock removal, internal movements, or production supply.
  When customizing or implementing supply source determination in EWM, especially if you have set the system to require full master data redefinition.
  When there is a mismatch between the supply source determination settings and the actual master data available or the way the system is called.
  
  
  Solution:
  
  
  Check Supply Source Determination Settings:
  
  Go to the customizing path in SAP EWM:
  SPRO -> Extended Warehouse Management -> Cross-Process Settings -> Supply Chain Execution -> Supply Source Determination
  
  Verify the settings related to master data redefinition.
  Ensure that the system is configured consistently to either:
  
  Redefine all master data during supply source determination, or
  Allow partial redefinition if that is supported.
  
  
  
  
  
  Adjust Master Data Redefinition Flag:
  
  If the system requires full master data redefinition, make sure that the process or program triggering supply source determination complies with this.
  If partial redefinition is needed, adjust the configuration or program logic accordingly.
  
  
  
  Review Custom Code or Enhancements:
  
  If you have custom developments or user exits/enhancements related to supply source determination, check if they are handling master data redefinition properly.
  Ensure that the custom code does not bypass or conflict with the standard supply source determination logic.
  
  
  
  Check Master Data Completeness:
  
  Verify that all relevant master data (product master, storage bins, source determination rules, etc.) are correctly maintained and consistent.
  Missing or inconsistent master data can cause the system to fail in supply source determination.
  
  
  
  SAP Notes and Support:
  
  Check for any SAP Notes related to WT707 for your specific SAP EWM version.
  Sometimes, patches or corrections are provided by SAP to handle specific scenarios.
  
  
  
  
  Related Information:
  
  
  Supply Source Determination in SAP EWM:
  
  It is a process to find the appropriate source location or stock for fulfilling warehouse requests.
  It depends heavily on master data like product master, storage bin master, stock information, and source determination rules.
  
  
  
  Master Data Redefinition:
  
  Refers to the process of refreshing or reloading master data during supply source determination.
  Full redefinition means all relevant master data is reloaded to ensure accurate source determination.
  Partial redefinition might only reload some data, which can lead to inconsistencies if not supported.
  
  
  
  Transaction / Program Involved:
  
  The error might appear during warehouse task creation (e.g., via transaction /SCWM/TO_CONF or during background processing).
  It can also appear in custom programs or interfaces that trigger supply source determination.
