  The SAP error message /DSD/SL_COCI002 indicates that there is an attempt to create or process a line item in a document (such as a sales order, delivery, or invoice) that already contains a line with the same material item. This typically occurs in the context of the SAP Direct Store Delivery (DSD) module, where multiple line items are being processed.
  Cause:
  The error is caused by the following scenarios:
  
  Duplicate Entry: The same material item is being added to a document that already contains that item. This can happen if the user tries to add the same product multiple times.

  Check Existing Line Items: Review the document you are trying to create or modify. Look for existing line items that may already include the material item in question. If it exists, you may need to update the quantity of that line item instead of adding a new one.
  
  
  Modify the Document: If you need to change the quantity of the existing material item, do so instead of trying to add a new line. 
  
  
  Review Input Data: Ensure that the data being inputted does not contain duplicates. If you are using a program or interface to upload data, check the logic to prevent duplicates.
  
  
  Consult Documentation: Review the SAP documentation or configuration settings related to the DSD module to understand any specific rules or settings that may be causing this error.
