Hello,
the version number of the trip is depending from the status of the trip.
If you create a business trip the version number is 099. It will not change if you apporve settle, transfer to FI and post the trip.
After this pcomplete process: If you change now and save again the posted trip: a new version 098 will be created. The reason: Both versions will be compared to find out the difference- this is needed for the posting process.
Example: receipt = 15 USD will be settled, transfer, posted to FI
I change now the trip and change the receipt amount to 16 USD. The posting amount is now the difference: 1 USD (coming from the compare of version 99 and 98)
Otherwise: If you now delete the changed trip you will get back the version 99 of the trip with the first status (posted to FI).
Hope thsi clarifys the system behaviour.
BR
Klaus
