• Message type: E = Error

• Message class: W_DSD_01 - Global message class for DSD

• Message number: 025

• Message text: There are material/store combinations without a main suppl. assignment

What causes this issue?

At least one material/store combination does not have a main vendor
assignment.

System Response

Every material/store combination must have exactly one main vendor
assignment at the given key date. Hence, it is not allowed to remove a
main vendor assignment without selecting another vendor to be the main
vendor for this material/store combination.

How to fix this error?

You must select one vendor as main vendor for those material/store
combinations that currently have no main vendor assignment.
You can use the toolbar function "Show/Hide Missing Main Vendors" to
display the material/store combinations that do not have a main vendor
assignment. In this filtered view, you also have the option to set all
missing main vendors in one step, by using the function "Set Missing
Main Vendors". If required, these main vendor proposals can be adjusted
manually.

• What is the cause and solution for SAP error message W_DSD_01025 - There are material/store combinations without a main suppl. assignment ?

  SAP Error Message:
  
  W_DSD_01025 – There are material/store combinations without a main supplier assignment.
  
  Cause:
  This warning message occurs in SAP when certain material and plant (store) combinations do not have a main supplier assigned in the system. In the context of SAP's Distribution and Supply Chain processes (especially in modules like SAP Retail or SAP MM), each material stored at a particular plant or store should have a designated main supplier to ensure proper procurement and supply chain management.
  If the system detects that some material/store combinations lack this main supplier assignment, it triggers this warning to alert the user that the master data is incomplete or inconsistent.
  
  Explanation:
  
  Material/Store combination: Refers to a specific material (product) assigned to a particular store or plant.
  Main supplier assignment: The primary vendor or supplier responsible for supplying that material to the store.
  
  Without this assignment, procurement processes, replenishment, and vendor evaluation may be impacted.
  
  Solution:
  
  
  Identify the affected material/store combinations:
  
  Use the report or transaction that triggered the warning to get a list of materials and stores missing the main supplier.
  Alternatively, use standard SAP reports or queries to find materials without a main supplier in the relevant plants.
  
  
  
  Assign a main supplier:
  
  Go to the material master data maintenance transaction (e.g., MM02).
  Navigate to the Purchasing view or the relevant view where supplier assignments are maintained.
  Assign the main supplier for the material at the plant/store level.
  Alternatively, use vendor master data and source list maintenance (transaction ME01) to assign source of supply.
  
  
  
  Check source list and info records:
  
  Ensure that source lists and purchasing info records are maintained correctly for the material/store combination.
  This helps in automatic determination of the main supplier.
  
  
  
  Re-run the process/report:
  
  After assigning the main suppliers, re-execute the process or report to confirm that the warning no longer appears.
  
  
  
  
  Related Information:
  
  
  Transactions:
  
  MM02 – Change Material Master
  ME01 – Maintain Source List
  ME11 – Create Purchasing Info Record
  MM03 – Display Material Master (to check current assignments)
  Custom or standard reports related to supplier assignment checks
  
  
  
  Master Data Consistency:
  
  This warning is part of master data validation to ensure procurement processes run smoothly.
  Missing main supplier assignments can cause issues in purchase order creation, automatic replenishment, and vendor evaluation.
  
  
  
  SAP Modules:
  
  Common in SAP MM (Materials Management), SAP Retail, and SAP SCM environments.
  
  
  
  
  Summary:
  
  Cause: Material/store combinations lack a main supplier assignment.
  Effect: Procurement and supply chain processes may be disrupted.
  Solution: Assign main suppliers to all material/store combinations via material master and source list maintenance.
  Check: Use relevant SAP transactions and reports to identify and correct missing assignments.
