SMSF recontribution and actual electronic transaction records

Hi,
I have a fully segregated single member SMSF, part in pension phase and part in accumulation phase. Last FY I requested a lump sum payment (partial commutation?) from the Accumulation phase (letters minutes etc in place) which was to be accomplished electronically via 3 separate transactions. However at the last minute, I decided to recontribute back a small amount from the final payment, and thoughtlessly, the final payment and recontribution were combined into one resultant transaction. (i.e. there is no electronic trail showing the contribution, but rather the actual full payment is less than the agreed sum by that contributed amount).

It has now been indicated to me that the ATO requires a full electronic transaction trail, despite the existence of signed agreements and minutes, so this transaction has to be recorded for accounting purposes solely as a lump sum payout with no recontribution. Is that the undisputed position, or are there alternative arguments?

Thanks for any assistance, for what I suspect is a common situation.
