What causes this issue?

You have selected a vendor-store-material relationship for sales price
calculation, but the selected vendor is not the main vendor for this
relationship.

System Response

If you have assigned multiple vendors to a specific material and store
for the same period of time, the system performs the sales price
calculation for the main vendor only, as you cannot calculate sales
prices for multiple vendors. This is due to the fact that only one sales
price per material and store can be saved. Therefore, the system uses
the purchase price of the main vendor to calculate the sales price.

How to fix this error?

Select another row for this material and store, where the corresponding
vendor is marked as main vendor.

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.

  SAP Error Message:
  W_DSD_01011 Supplier &1 is not a main supplier for material &2 and store &3
  
  Cause:
  This warning message occurs in SAP when you try to perform a transaction or process involving a supplier who is not defined as a main supplier for the specified material (&2) and plant/store (&3). In SAP, the concept of a "main supplier" is used to identify the primary or preferred supplier for a material at a particular plant or store.
  The system checks the supplier master data and material master data to verify if the supplier is assigned as a main supplier for the material in the given plant. If the supplier is not assigned as a main supplier, this warning is triggered.
  
  When does it typically occur?
  
  During purchase order creation or goods receipt when the supplier is specified.
  When using vendor evaluation or source list checks.
  In DSD (Direct Store Delivery) scenarios or other specialized procurement processes where main supplier assignment is critical.
  
  
  Solution:
  
  
  Check Supplier Assignment:
  
  Verify if the supplier (&1) is assigned as a main supplier for the material (&2) in the specified plant/store (&3).
  Use transaction MM02 (Change Material Master) or MM03 (Display Material Master) to check the purchasing data.
  Check the Source List (transaction ME01, ME03) to see if the supplier is listed as a source of supply for the material and plant.
  
  
  
  Assign Supplier as Main Supplier:
  
  If the supplier should be the main supplier, assign them accordingly.
  In the material master purchasing view, assign the supplier as the main supplier for the plant.
  Alternatively, maintain the source list to include the supplier as a valid source.
  
  
  
  Adjust Process or Ignore Warning:
  
  If the supplier is not intended to be a main supplier, and the warning is acceptable, you may proceed with caution.
  Sometimes this warning can be ignored if the business process allows using non-main suppliers.
  
  
  
  Check Customizing Settings:
  
  In some cases, the system behavior regarding main supplier checks can be controlled via customizing.
  Check if the warning can be downgraded or suppressed if business requirements allow.
