• What is the cause and solution for SAP error message WS665 - Cross-application document numbering is not active; CoCode &1, DocType &2 ?

  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  WS665 - Cross-application document numbering is not active; CoCode &1, DocType &2
  
  Cause:
  This error occurs when you try to post a document in a company code (CoCode) and document type (DocType) for which cross-application document numbering is not activated. In SAP, cross-application document numbering means that documents across different application components (e.g., FI, MM, SD) share a common numbering sequence.
  If this setting is not active for the specified company code and document type, the system expects document numbering to be handled separately within each application. Attempting to post a document with cross-application numbering enabled (or expected) without proper configuration triggers this error.
  
  Explanation:
  
  Cross-application document numbering allows multiple SAP modules (FI, MM, SD, etc.) to use a common document number range.
  If this is not activated, each module manages its own document numbering independently.
  The error indicates that the system expects cross-application numbering to be active but it is not configured for the given company code and document type.
  
  
  Solution:
  To resolve this error, you need to activate cross-application document numbering for the relevant company code and document type.
  Steps to activate cross-application document numbering:
  
  
  Go to SPRO (SAP Reference IMG):
  
  SPRO ? Financial Accounting (New) ? Financial Accounting Global Settings (New) ? Document ? Cross-Application Components ? Activate Cross-Application Document Numbering
  
  
  Activate the setting for the company code and document type:  
  
  Select the company code (CoCode) and document type (DocType) for which you want to enable cross-application numbering.
  Mark the checkbox to activate cross-application document numbering.
  
  
  
  Assign Number Ranges:  
  
  Ensure that the number ranges assigned to the document type are set up for cross-application numbering.
  You can check and maintain number ranges in transaction FBN1 (Number Range Maintenance for Accounting Documents).
  
  
  
  Save and test:  
  
  After activation, try posting the document again.
  
  
  
  
  Additional Information:
  
  
  Transaction Codes:
  
  FBN1 – Number Range Maintenance for Accounting Documents
  OBYR – Define Document Types for Cross-Application Document Numbering
  SPRO – SAP Reference IMG for configuration
  
  
  
  Notes:
  
  Activating cross-application document numbering affects how document numbers are assigned and can impact integration between modules.
  Make sure to coordinate with your SAP FI and MM/SD teams before making changes.
  Backup current settings before changes.
