Dear Vikash ji,

If challan is showing in Mismatch status then it allows us to correct various fields viz date, tds amount, bsr code,challan no etc. 

which software you are using rpu not allow to modify other field.

Dear Lalitji,

It is RPU only Check first whether challan is showing in mismatch status.

Chllan is showing mismatch with light blue colour, I have called to nsdl help desk they suggested to me this can not be change only assessing officer can change the detail than I will have to contact to A.O.

but I want to know that, is this last option to change the challan details any other option is available or not?

i am unable to change dates.. message says only last row can be deleted.. complete correction is not possible ??
