In Tally 7.2, the most common problem is any time data got corrupted and you can’t log in to the company.
Solutions to that problem was to take back up frequently of your work however again you have to re enter all your entries since last back up time which is a big hazard
The best solution to the problem is migrate to tally.erp 9 as till date I never see any single instance of this problem and I never lose any my single entry after migrating to tally.erp 9 in spite of so many power disturbance or any other reason
One another good feature of tally.erp 9 is that u can take back up (by copy paste method) at any time even if you are working on it, viewing any ledger or printing or making entry which was not possible in earlier version of tally.
However, if due to some reason, you still love to stick to outdated version of tally 7.2 and if your data corrupted, then here is an another solution to this.
Start your tally and go to main menu. (if your tally load the company by default then disable it by editing tally.ini file)
Now PRESS alt+ctr+R ( R means Re-write ). This option is well known as Re write books of account.
You will be prompted to select the company to re-write. Select and confirm.
It will display the process in progress, wait until it finish 100%
If your luck is good then the process will finish 100% and you will be able to get your data back and can work again otherwise, tally will quite and you have to restore your old data back up if the same is handy, but if not then you have no option except writing all the entries again.
