It provides a structured way to control time-based accounting, posting, and reporting<\/strong>. In iDempiere, the Calendar<\/strong>, Year<\/strong>, and Period<\/strong> define when transactions can be recorded, which periods are open or closed, and how financial reports are grouped. This ensures accurate accounting control and regulatory compliance in iDempiere<\/strong>.<\/p>\n\n\n\n

Relationship between Calendar, Year, and Period<\/strong><\/h2>\n\n\n\n

The Calendar is the top-level structure that defines an organization\u2019s financial timeline. A Calendar contains one or more Years<\/strong>, and each Year is divided into Periods<\/strong>.<\/p>\n\n\n\n

This hierarchy works as<\/strong><\/h3>\n\n\n\n
    \n
  • Calendar<\/strong> \u2192 defines the overall fiscal structure<\/li>\n\n\n\n
  • Year<\/strong> \u2192 represents a fiscal year (for example, FY 2025\u201326)<\/li>\n\n\n\n
  • Period<\/strong> \u2192 represents a smaller time unit within the year (month)<\/li>\n<\/ul>\n\n\n\n

    All accounting activity is validated against this structure.<\/p>\n\n\n\n

    \"\"<\/figure>\n\n\n\n

    Year \u2013 defining the fiscal year<\/strong><\/h2>\n\n\n\n

    A Year in iDempiere represents a fiscal or accounting year, which may or may not align with the calendar year. The Year defines:<\/p>\n\n\n\n

      \n
    • Whether the year is active and available for posting<\/li>\n\n\n\n
    • The periods that belong to that year<\/li>\n<\/ul>\n\n\n\n

      Organizations can define multiple years in advance to support future postings and planning.<\/p>\n\n\n\n

      \"\"<\/figure>\n\n\n\n

      Period \u2013 controlling when transactions can be posted<\/strong><\/h2>\n\n\n\n

      Periods are the most critical control point. Every transaction date falls into a specific period, and iDempiere checks the period status<\/strong> before allowing posting.<\/p>\n\n\n\n

      Each period defines<\/p>\n\n\n\n

        \n
      • The Period name<\/li>\n\n\n\n
      • Start date<\/strong> and End date<\/strong> of the period (For example: 01\/01\/2025 \u2013 01\/31\/2025)<\/li>\n<\/ul>\n\n\n\n

        It also defines two period types<\/p>\n\n\n\n

          \n
        • Standard Calendar period<\/li>\n\n\n\n
        • Adjustment Calendar period<\/li>\n<\/ul>\n\n\n\n
          \"\"<\/figure>\n\n\n\n

          An adjustment calendar period<\/strong> is a special timeframe used in accounting systems for final year-end entries, adjusting balances, and closing books after regular periods, allowing for precise corrections without affecting live operational data.<\/p>\n\n\n\n

          Period control by document types<\/strong><\/h2>\n\n\n\n

          iDempiere allows periods to be controlled per document type<\/strong> (for example, Purchase Invoice, Sales Invoice, GL Journal). This means<\/p>\n\n\n\n

            \n
          • One document type can be open while another is closed<\/li>\n\n\n\n
          • Finance teams can phase-close periods gradually<\/li>\n<\/ul>\n\n\n\n

            This provides flexibility during month-end and year-end closing.<\/p>\n\n\n\n

            \"\"<\/figure>\n\n\n\n

            How periods affect document processing<\/strong><\/h2>\n\n\n\n

            When a document is completed or posted<\/p>\n\n\n\n

              \n
            1. iDempiere checks the document date<\/li>\n\n\n\n
            2. The system identifies the corresponding period<\/li>\n\n\n\n
            3. The period status is validated for the organization and document type<\/li>\n<\/ol>\n\n\n\n

              If the period is not open, the system blocks completion or posting. This prevents backdated or unauthorized accounting entries.<\/p>\n\n\n\n

              Year-end closing and rollover<\/strong><\/h2>\n\n\n\n

              At year end<\/p>\n\n\n\n

                \n
              • All periods are closed<\/li>\n\n\n\n
              • Final adjustments are posted<\/li>\n\n\n\n
              • The next year\u2019s periods are opened<\/li>\n<\/ul>\n\n\n\n

                iDempiere ensures that once a year is closed, historical data remains unchanged, protecting financial integrity.<\/p>\n\n\n\n

                By using Calendars, Years, and Periods together, iDempiere enforces strong time-based control over accounting and reporting<\/strong>. This structure prevents unauthorized postings, supports accurate period closing, and enables reliable financial analysis across fiscal years.<\/p>\n","protected":false},"excerpt":{"rendered":"
