  SAP Error Message:
  WRF_APC_INB160 Duplicate entry (PUR_TAB) Vendor: &1 POrg: &2 PGroup: &3 CVAL: &4
  
  Meaning / Cause:
  This error occurs during the inbound processing of vendor master data (usually in SAP APO or SAP ERP integration scenarios) when the system detects a duplicate entry in the purchasing data table (PUR_TAB) for a vendor.
  
  Vendor: The vendor number for which the duplicate entry exists.
  POrg: Purchasing Organization.
  PGroup: Purchasing Group.
  CVAL: The conflicting value (usually a key field or combination of fields that should be unique).
  
  The system expects unique combinations of vendor, purchasing organization, and purchasing group in the purchasing data table. If the same combination appears more than once, the system throws this error to prevent inconsistent or redundant data.
  
  Typical Causes:
  
  Duplicate entries in the inbound IDoc or data file.
  Data inconsistency in the source system.
  Incorrect or repeated data mapping during data transfer.
  Manual creation or update of vendor purchasing data leading to duplicates.
  Incomplete or incorrect data cleansing before data upload.
  
  
  Solution / How to Fix:
  
  
  Check the inbound data:
  
  Review the inbound IDoc or data file to identify duplicate entries for the vendor, purchasing organization, and purchasing group.
  Remove or correct duplicates before reprocessing.
  
  
  
  Check existing vendor master data:
  
  In SAP ERP, use transaction XK03 or MK03 to display vendor master data.
  Check the purchasing data tab for the vendor to see if duplicate entries exist.
  If duplicates exist, clean up by deleting or correcting redundant entries.
  
  
  
  Data cleansing:
  
  Ensure that the source system or middleware sending the data does not send duplicate records.
  Implement validation checks in the data transfer process.
  
  
  
  Reprocess the inbound data:
  
  After correcting the data, reprocess the inbound IDoc or data file.
  
  
  
  Check customizing and mapping:
  
  Verify that the mapping logic in the middleware or integration tool correctly handles vendor purchasing data.
  Ensure no duplication occurs due to mapping errors.
