The entry which you typed here ... can't be explain because you have to look the above entries by which you could relate things.
For Example - Hemansh purchase goods for ₹ 10,000
Hemansh returned goods worth ₹ 2000.
So, in here.. the entry would be.
Cash A/c Dr. ₹2000
To P/R ₹2000
P/R or Purchase Return has Credit Balance.
So, the main thing is that you have to relate the previous Entries to got know that whether is it purchase or sale return.
