Value 'Erste Hilfe ' (hex' ') of characteristic 0MATERIAL contains invalid

Dear All.

i am extracting the data from R/3 for infosource 2LIS_13_VDITM and during extraction it fails due to this single record which is marked as error.

Value 'Erste Hilfe ' (hex. ' ') of characteristic 0MATERIAL contains invalid character

when i check the record in the PSA in Material field instead of Material number this value was there i.e.

Erste Hilfe.

you advice to resolve this issue and tip on cleansing will be highly appreciated

Kind regards,

Zeeshan
