The e-Mandate registration may fail due to various reasons:
· Incorrect login ID and password provided during registration.
· The bank account linked to the mandate may have been closed.
· The Mandate ID generated may have expired before the registration attempt. (Mandate IDs typically have a validity period of 90 days.)
· The bank may not support the Net Banking autopay feature required for e-Mandate registration.
· The user's trading account may not be in active status, which is necessary for the mandate registration process to proceed successfully.
