The Document prefix panel is composed of the only field: Value. The field is intended to specify the value to be added to the document number.

Any value suitable for document numbers can be entered in this field to be added to automatically generated document numbers for the store.

To automatically add a store prefix to the document number, in the Number generators directory, select the required document number format for the selected document type. When creating a document number format in the Number settings directory, use the dnf_GetStoreSignature procedure in SQL queries to get store prefixes.
