Purchase order display - short text in logon language

Hello,

The material description in our purchase orders are in the vendor language. For our foreign vendor, it's better to read the material description in our language.

But our internal requirement, is : how to display the material description in logon language using ME23N, ME2N, ME2M ... it's better for us to see the material description in user language to analyze the data.

I've seen this answer in the OSS note 491211 - FAQ: Purchase order (general)

Question: Why is the material short text not displayed in the logon language in the purchase order even though it is stored in the logon language in the material master?

Answer:When the purchase order is created, the short text is transferred in the document language and copied to the purchase order. Afterwards, the system displays this copied and possibly changed short text always in display mode regardless of the logon language.

what does this sentence mean exactly "possibly changed short text always in display mode regardless of the logon language" ?

is there any parameter to set ?

Thanks for your help

Regards

Grégory
