Friends, While preparing e-tds/e-tcs return, now mobile number is mandatory in RPU 2.2 or RPU 2.3. In the absence of Mobile Number, fvu (File Validity Utility) file is being rejecting by NSDL or any nodal office. No doubt that Mobile Number is not marked as (*) for mandatory option, but without it's feeding, uploading of fvu is not possible.
Major Solution for acceptance of e-tds/e-tcs return
Enter Mobile Number ,create FVU and get success.
