Problem:
The plant number is missing.

Error received: Document rejected, reject type: FORCED_AUTO, reason: - The factory number is not correct. Valid plant numbers can be found at: https://supplier.mercedes-benz.com/portal/zusammenarbeit/fo (for Cars plants in Europe: https://supplier.mercedes-benz.com/docs/DOC-3145) If you have a valid plant number printed on your document, please open a support case: https://basware.service-now.com/bw 

Solution:
The plant number (Werk) is a mandatory information for the types of invoice SL, SO, SP and FS. Without this specification, your invoices can not be processed.

Please always use a unique anchor word, such as "Plant number" or "Werksnummer" and make sure that it always has to be specified in 3-digit form.
e.g. WERK 000

This value can be placed along with other information on the buyer, e.g. next to buyer address.

Normally the unique indicator (the anchor word) should have been agreed during the test phase. It should be noted that this is ALWAYS to be used as agreed. Additional information can be found in your customer's Supplier Kit.
