• What is the cause and solution for SAP error message MB_CROSS_SYSTEM004 - Postings with automatic lines are not possible ?

  The SAP error message MB_CROSS_SYSTEM004 indicates that there is an issue with posting transactions that involve automatic accounting entries across different systems. This typically occurs in scenarios where you are trying to post a document that requires automatic accounting entries to be generated, but the system detects that these entries would involve different systems (e.g., different company codes or different SAP systems).
  Cause:
  
  Cross-System Posting: The error usually arises when you attempt to post a document that involves automatic postings (like inventory movements) that span across different systems or company codes that are not configured to allow such transactions.
  Configuration Issues: There may be configuration settings in the SAP system that prevent cross-system postings, such as settings in the document types, company codes, or controlling areas.
  Inconsistent Master Data: If the master data (like material master, vendor master, etc.) is not consistent across the systems, it can lead to this error.
  Missing Authorizations: Sometimes, the user may not have the necessary authorizations to perform cross-system postings.
  
  Solution:
  
  Check Configuration: Review the configuration settings for the relevant company codes and document types. Ensure that they are set up to allow cross-system postings if that is the intended functionality.
  Use the Same System: If possible, ensure that all postings are done within the same system or company code to avoid this error.
  Review Master Data: Ensure that all relevant master data is consistent and correctly set up in both systems. This includes checking for any discrepancies in material numbers, vendor numbers, etc.
  Authorization Check: Verify that the user has the necessary authorizations to perform the posting. If not, work with your SAP security team to obtain the required permissions.
  Consult SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional guidance on configuration settings.
