SAP Error Message - Details

• Message type: E = Error

• Message class: OC - IS-Oil: BDRP Bulk Distribution Requirement Planning messages

• Message number: 512

• Message text: At least one duplicate entry was deleted from the uploaded data

What causes this issue?

A duplicate entry was found in the LVCC data that was uploaded from a
local file. This was probably due to linear constant entries in the
local file having a greater number of decimal places than specified in
the 'Nr Dec places' field. The system formats the linear constant
entries to the specified decimal place mask. If the incoming data
contains entries with a greater number of decimal places than available
in the mask, truncation will occur.

System Response

Processing continues, but with a reduced set of entries.

How to fix this error?

Determine the maximum number of decimal places used in the linear
constant of the LVCC data in your local file. Set the number of
decimal places on the 'Change lin/vol conversion (strapping) data'
screen to this number before uploading the local file.

• What is the cause and solution for SAP error message OC512 - At least one duplicate entry was deleted from the uploaded data ?

  The SAP error message OC512, which states "At least one duplicate entry was deleted from the uploaded data," typically occurs during data uploads or data processing activities in SAP systems. This message indicates that the system has detected duplicate entries in the data being uploaded and has automatically removed at least one of those duplicates to maintain data integrity.
  Cause:
  
  Duplicate Data: The primary cause of this error is the presence of duplicate records in the data file being uploaded. This can happen if the data source contains repeated entries or if the same data is inadvertently included multiple times.
  Data Validation Rules: SAP has built-in validation rules that check for duplicates based on specific fields or criteria. If the data being uploaded violates these rules, the system will flag the duplicates.
  Configuration Settings: Certain configurations in the SAP system may enforce strict data integrity checks, leading to the automatic deletion of duplicates.
  
  Solution:
  
  Review the Data Source: Check the source of the data being uploaded to identify and eliminate any duplicate entries before the upload process. This can be done using data processing tools or scripts to filter out duplicates.
  Data Cleansing: Implement data cleansing techniques to ensure that the data is unique. This may involve using Excel, SQL queries, or data management tools to identify and remove duplicates.
  Adjust Upload Settings: If applicable, review the settings of the upload process to see if there are options to handle duplicates differently (e.g., allowing duplicates, merging records, etc.).
  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines on handling duplicate entries in the context of the particular module or transaction you are working with.
  Testing: After making changes to the data or settings, conduct a test upload with a smaller dataset to ensure that the issue is resolved before proceeding with larger uploads.
