You need to create a new document type for a document category in SAP Materials Management. What do you need to define?

To create a new document type for a document category in SAP Materials Management, it is essential to define the linkage of document types. This linkage allows the new document type to interact appropriately with other document types in the system, ensuring that they can be recognized and processed correctly within various procurement and inventory processes.

Establishing this linkage is crucial for maintaining a coherent flow of data and document handling across different document categories, such as purchase orders or contracts. It helps to set up the relationships between different documents, allowing for functionalities like referencing or integrating information from one document type to another efficiently.

In contrast, defining the assignment of the document type for a purchasing organization, function authorizations for document types, or permitted item categories, while also important, does not directly pertain to the fundamental requirement of linking the new document type to existing ones for optimal operational integration. These aspects can follow but the initial step hinges on correctly establishing the linkage of document types.
