It provides a single, validated accounting structure<\/strong> that combines the General Ledger account with multiple accounting dimensions into one usable accounting record.<\/p>\n\n\n\n

In iDempiere, this is known as a Valid Combination<\/em>, and it represents the exact account that will be posted to accounting in iDempiere<\/strong>.<\/p>\n\n\n\n

Purpose of the Account Combination<\/strong><\/h2>\n\n\n\n

iDempiere does not post transactions using only a single GL account. Instead, it posts using a combination of dimensions<\/strong> such as Account, Organization, Product, Project, Business Partner, Activity, and others.<\/p>\n\n\n\n

The Account Combination window brings all these dimensions together and validates them as a single accounting identity. This ensures consistency, control, and accuracy in financial postings.<\/p>\n\n\n\n

Relationship between dimensions and accounting postings<\/strong><\/h2>\n\n\n\n

Each Account Combination represents one unique set of accounting dimensions. When a transaction is posted<\/p>\n\n\n\n

    \n
  • The system derives the required dimensions from the document (for example, product, project or organization)<\/li>\n\n\n\n
  • These values are matched to a valid account combination<\/li>\n\n\n\n
  • The posting is made using that combination<\/li>\n<\/ul>\n\n\n\n

    If a valid combination does not exist, iDempiere can either create it automatically or block posting, depending on configuration.<\/p>\n\n\n\n

    Why account combinations are needed<\/strong><\/h2>\n\n\n\n

    Without account combinations, iDempiere would have to dynamically build accounting entries every time a document is posted. Instead, it uses predefined or auto-generated combinations to<\/p>\n\n\n\n

      \n
    • Enforce accounting rules<\/li>\n\n\n\n
    • Prevent invalid dimension usage<\/li>\n\n\n\n
    • Maintain clean and auditable accounting data<\/li>\n<\/ul>\n\n\n\n

      This approach is especially important in multi-project and multi-organization environments.<\/p>\n\n\n\n

      How combinations are created and maintained<\/strong><\/h2>\n\n\n\n

      Account combinations can be<\/p>\n\n\n\n

        \n
      • Automatically generated<\/strong> by iDempiere during posting<\/li>\n<\/ul>\n\n\n\n

        Once created, a combination is reused whenever the same set of dimensions appears again. This avoids duplication and ensures consistent postings across documents.<\/p>\n\n\n\n

        Controlling which dimensions are used<\/strong><\/h2>\n\n\n\n

        The dimensions available in the Account Combination window depend on<\/p>\n\n\n\n

          \n
        • The Accounting Schema<\/li>\n\n\n\n
        • Enabled accounting dimensions (such as Project, Product, Organization)<\/li>\n<\/ul>\n\n\n\n

          Optional dimensions may be empty, while mandatory dimensions must be present for the combination to be valid. This explains why some postings include many dimensions while others include only a few.<\/p>\n\n\n\n

          By centralizing all accounting dimensions into validated combinations, the Account Combination window ensures accurate postings, strong control, and flexible financial reporting<\/strong> in iDempiere. It forms the foundation that connects operational transactions to structured, auditable accounting data.<\/p>\n","protected":false},"excerpt":{"rendered":"
