BIP5455
Severity
20 : Error
Message
Occurence (<insert_0>) of ACORD AL3 Element (<insert_1>) at offset (<insert_2>)is invalid in the bitstream.
Explanation
An earlier occurence of repeating Element (<insert_1>) has been marked as not present. In an ACORD AL3 message, once an occurence of a repeating element has been marked as not present then no subsequent occurrences of that repeating element may be present. The presence of a '?' in the left most position of an element's data is used to signify that the element is not present.
Response
Check that your model definition is correct and that the maximum occurences for Element (<insert_3>) is correct. If the model is correct, make sure that the incoming message is a valid ACORD AL3 TDS message.
