the Link in SAP Business One describes the structural relationship between various business objects such as documents, master data and analysis elements and thus ensures end-to-end process transparency and the complete traceability of business transactions in SAP Business One. SMEs-environment.

In SAP Business One, linking is the fundamental concept for the document and value flow. This allows related documents to be linked systematically so that users can recognise at any time how a process develops from the first entry to the last subsequent document. In addition, the Linkage plan as the primary tool, displays these relationships graphically and shows the entire document flow or value history of a transaction.
In the linking plan, the colour indicates the status of the documents. For example, a green symbol indicates that a document is closed or completed. In contrast, orange or yellow borders mark Open vouchers, especially if their due date is imminent. The system also highlights the currently open document in blue, while a light blue border indicates a document reference. Users can therefore quickly determine the processing status of the linked documents via the visualisation.
Users call up the link plan directly from the respective document. This allows the history and subsequent documents of a transaction to be identified immediately. This makes it clear, for example, whether an order has been delivered and invoiced in full. This view also supports the control of process chains in almost all sales and purchasing documents.
In practice, links are created at different levels. The most common form is based on the copy functions Copy from and Copy to. When a base document such as a quotation or sales order is copied to a target document such as a delivery or outgoing invoice, the process chain is automatically established. Consequently, this chain is retained and is clearly visualised in the linking plan.
Users can also manually link documents that are outside the direct logical flow. The field Reference document, via which, for example, a credit amount is referenced with the original outgoing invoice as a gesture of goodwill. In addition, when duplicating a data record, it is often possible to automatically store a reference to the original document. This ensures that the relationship between the documents is documented transparently, even in special cases.
Furthermore, links play an important role in analysis functions and financial accounting. About Views the detailed view of a master data record can be linked to a filtered list view of another object. Specifically, the system automatically displays all outgoing invoices that belong to the business partner whose master data record is currently open. This gives users a contextualised view of all relevant documents without having to make additional selections.
In financial accounting, the system uses the field Origin, to identify the underlying document of an automatic journal entry. An abbreviation of the document type that caused the posting is saved there (e.g. „RE“ for outgoing invoice). The navigation arrow takes users directly from the journal entry record to the originating document. This means that the link between the financial posting and the operational business transaction can be traced at all times.
Demarcation:
The context provided describes the link as an overarching mechanism for connecting business objects and delineates it internally through various characteristics such as copy functions, referencing via reference document, views and the Origin field, without defining other independent terms or concepts outside of this context.
