• What is the cause and solution for SAP error message KM179 - EC-PCA document contains either no document number or no logical system ?

  The SAP error message KM179 indicates that there is an issue with the EC-PCA (Enterprise Controlling - Profit Center Accounting) document, specifically that it either lacks a document number or a logical system. This error typically arises during the processing of documents in the EC-PCA module, which is used for internal accounting and reporting purposes.
  Cause:
  
  
  Missing Document Number: The document being processed does not have a valid document number assigned to it. This could happen if the document was not created properly or if there was an error during the document creation process.
  
  
  Missing Logical System: The logical system, which is necessary for identifying the source of the data, is not defined for the document. This could occur if the configuration for the logical system is incomplete or if the document is being processed in a system that does not recognize the logical system.
  
  
  Data Transfer Issues: If the document is being transferred from another system (e.g., during a data migration or integration process), there may be issues with the data transfer that result in missing information.
  
  
  Solution:
  
  
  Check Document Creation: Verify that the document was created correctly. Ensure that all required fields, including the document number and logical system, are populated during the document creation process.
  
  
  Review Configuration: Check the configuration settings for the logical system in the SAP system. Ensure that the logical system is correctly defined and that it is associated with the appropriate client.
  
  
  Data Consistency Check: Run consistency checks on the documents in the EC-PCA module to identify any inconsistencies or missing data. This can help pinpoint the specific documents that are causing the error.
  
  
  Reprocess the Document: If the document was created incorrectly, you may need to delete it and recreate it with the correct information.
  
  
  Consult SAP Notes: Check the SAP Support Portal for any relevant SAP Notes that may address this specific error message. There may be patches or updates that resolve known issues related to this error.
  
  
  Debugging: If the issue persists, consider debugging the process to identify where the document number or logical system is being lost. This may require assistance from a technical consultant or SAP support.
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as KE5Z (Display Profit Center Document) or KE5Y (Display Profit Center Document: Line Items) to analyze the documents in question.
  SAP Documentation: Review the official SAP documentation for EC-PCA to understand the requirements for document creation and processing.
  User Exits and BAdIs: If custom logic is implemented in your SAP system, check for any user exits or BAdIs that may affect the document processing.
  
  By following these steps, you should be able to identify the root cause of the KM179 error and implement a solution to resolve it.
