I have 2 erronous records in a request PSA and I can't see what's wrong with them. The error Diagnosis shows (Sorry I replaced the real values with XXX for confidentiality reasons):
Data record XXXX & with the key 'XXXXXXXXX &' is invalid in value
'XXXXXX &' of the attribute/characteristic 0CUSTOMER &.
The concerned value was translated to upper cases as others values. All values were accepted except this one.
How can I know what's stuck a correct loading?
