Client is missing part of a posting in GL. AR Cash batches were posted and retrieved. GL batch status report shows 83 transactions with a total of 390,439.69.

AR Cash batch Status shows 83 transactions (in 8 batches)and a total of 389,961.49. (difference of 478.20)

The client tells me some of the transactions are missing.
The posting was cleared but using a source journal to recreate the GL batch, I can find only 33 of the transactions. This represents the first 4 and 2/3 batches from AR.
I used broad parameters on the source journal.
Data integrity is fine.
