Hi
The consumption journal entries are created by the "Calc. Consumption" report so if you want to affect the date that appears when you run the calculate consumption function this is where it will need to be done, this however is a function that creates journal entries
Be Very Very careful, modifying code that affects postings and journals can cause a ton of trouble, crazy errors and many late nights trying to figure out what went wrong, don't modify posting, journal or financial code unless you are extremely sure you know what the possible effects could be.
Cheers
