During nov,20 flipkart has filed TCS collection which is autopopulating in my tds/tcs credit received tile and I accepted resulting to credit in cash ledger.During dec,20 the same amount is also populating in tcs credit received tile and I accepted.As I had wrongly accepted the credit,I reversed the said amount through DRC03 on 15.2.21.
Now on 1.4.21 my cash ledger again debited by same amount having descripttion- amount recovery due to tcs credit taken twice in two different return period.When I verified the Tdc/ tcs credit tile filed for dec,20,the action column shows- counter party already amended.What does it mean?how the cash balance automatically debited?
