Hi Andrew,

We have already prevented posting to the control account in the A/R module. The error occurred during importing transactions with a CSV file. I believe that there was an error on the load file into the A/R module - it gave the person an error message at the time, so she thought it didn't post to the customer's A/R subledger account and so re-posted the transaction with a corrected load file. When she then checked the customer's account, the transaction was posted twice. The original posting is the one that seems to be causing the issue though.
