I upload 0MATERIAL and have plenty of errors like :
Record XXXX 'Value XXXXXXX for sharacteristic 0STD_DESCR' contains invalid characters.
I open PSA table , select whole 0STD_DESCR (not only invalid character) , copy-paste into list of permitted characters (tran RSKC). But it does help and errors appears again at the same record.
What do you reccomend to do?
