SAP Note 28027 - ME41: Material description in incorrect language

Symptom:

When you create a request for quotation, the material description is not issued in the language of the vendor.
The request for quotation is created, for example, with language indicator 'D' (German) (EKKO-SPRAS). The material description is then also issued in language 'D' (German). If you then, for example, enter a vendor in language 'E' (English), the request for quotation is still printed with a material description in German. The material description is also displayed in German, even if you log on in another language.

Other terms

ME41, ME42, ME43

Reason and Prerequisites

You cannot change the language after you have entered items of a request for quotation. As soon as a material description was issued in one language, you can no longer change the language. The language of the document and not the language of the vendor is the decisive language when printing the form. In purchase orders, the language of the vendor is proposed as document language; in requests for quotation, however, this is not possible.

Solution
Recommendation:
For English vendors log on to the system again with document language E (English). You can use a request for quotation that has already been entered in German as a reference; the short texts are then displayed in English.
Procedure:
Transaction ME41; Change language (EKKO-SPRAS); Button 'Item overview'; RFQ -> Create w. reference -> To ref. document (as of Release 4.0: RFQ -> Copy); enter the previous request for quotation and copy the items.
