Journals and Series

Understanding Documents: Journals and Series

To issue any document in the ERP system, you need to understand two core concepts: Journals and Series.

To make it simple, think of how a traditional office works with physical paper pads (blocks) bought from a bookstore.

What is a Journal? (The Type of Document)

The Journal defines what kind of transaction you are making. It is the category of the document. In the physical world, this is like having different shelves or drawers for each document type.

  • Invoice B2B Journal: The drawer where you keep only business invoices.
  • Retail Sales Receipt Journal: The drawer where you keep only retail receipts.
  • Delivery Note Journal: The drawer where you keep only shipping/delivery documents.

What is a Series? (The Specific Pad / Block)

The Series represents the actual, physical pad of paper you take out of the drawer to write on. Each pad has its own unique prefix (e.g., Series A, Series B) and its own independent, continuous numbering sequence (1, 2, 3…).

Even though two pads belong to the same Journal (document type), they do not mix their numbers.

Visual

Imagine your office desk has 6 distinct stacks (pads) of documents arranged like this:

  • If you issue an invoice from Invoice B2B -> Series A, the system will generate a number like INV-A-001.
  • If you issue the next invoice from Invoice B2B -> Series B, the system will look at that specific stack and generate a number like INV-B-001.
  • Selling to a retail customer? You must switch to a different drawer entirely: Retail Sales Receipt -> Series A.
