Stoleway – are you still confused why its 1,400 ?
If so then there is my attempt to help explain
Firstly the Booker did this JE
DR AR 700
CR Bank 700
We know this is wrong as CR Bank is reducing the bank balance instead of increasing it
Next the right JE is this.
DR Bank …. 700
CR AR …. 700
In order to correct this you need to post the the correct JE twice
Once to cancel the effect the incorrect JE had and the second one to book it the right way.
You can also instead of two doing JE's to correct the situation do one JE ins tea
DR Bank 1,400 ( One set of 700 to reverse Mistake and one set of 700 to book it the right way)
Cr AR 1400
