Attributes of Infoobject 0Material (DTP Problem)

Hello Experts,

I have an issue with a DTP thats loads the attributes of the Master Data 0Material.

The DTP fails and I am getting this error:

Diagnosis:

Data record 18 & with the key '000000000000000122 &' is invalid in value

'PPP:XYXY/PA_MP3*777+3.76&-98#88 &' of the attribute/characteristic

0MANU_MATNR &.

System Response:

The system has recognized that the value mentioned above is invalid, and

has processed this general error message. A subsequent message may give

you more information on the error. This message refers to the same

value, even though it does not state this explicitly.

This error is due to a modification in R/3, in fact we must use some special characters.

This special characters are accepted in R/3 but not in the BW, and i must load this special char in BW (no conversion)

The field MATNR (R/3) and 0Material (BW) have the same properties Char 18.

Do you have any ideas to fix this issue? Someone already met this error?

Thanks.

Amine

PS: I thought to implement a converion routine in the Infoobject properties (General tab), but as i explained, we have the constraint to keep the value in its origin form.
