What does Receipt applications validated exception mean in lockbox

Hello

While processing lockbox files we occasionally receive the following exception messages: Receipt applications validated

I check here for the list of lockbox error messages, and it is a valid message, however no explanation of what caused it or how to correct it, and maybe there is some other issue in the validation process that failed but triggered this exception.

Would greatly appreciate any suggestions on how to address this type of an exception.

Regards,

Sergei
