PAO File Validation Utility (PAO-FVU) for Contribution Files. 
 This utility is to be used for validation (format level) of PAO contribnution file before furnishing the file either online directly to NSDL or with a FC.
 The input screen of FVU has two fields viz; 'Input File' and 'Error/Upload & Control Sheet Report File'.

1.  Input File

1.1  Specify the name (with the .txt extension) of the input file (including the path) i.e. the name of the PAO Contribution File as per file format to be validated through the FVU.

1.2  Input filename should not be more than 12 characters (including the .txt extension) and should not contain any special characters eg. : , \ / etc.
For example Filename can be PAO1106.txt.



2.  Error/Upload & Control Sheet Report File

2.1  Specify the path where either an 'error' or 'upload & control sheet report files' generated by the FVU on completion of validation should be saved.
- The path can be same as the input file path or different.
- Do not specify any filename, only provide the path.

2.2  In case of an invalid file, an 'error file' will be generated. 
- This will be an html file (PAO1106err.html) with the same filename as the input file with err appended after the file name and html as extension. 
- The error file will contain details of erroneous records like Line no, record type, field name, DDO serial no. subscriber contribution detail no., along with the error code and the corresponding error description.
- The Accounts Officer will rectify the errors and validate the statement again through the FVU.

2.3  In case the input file is valid, FVU will generate three files:
- 'PAO Control Sheet Report' (PAO1106.html) which is a summary of the Contibution File validated by the FVU.
- 'Upload file' (PAO1106.fvu) which is generated with the same filename as the 'input file' but with extension .fvu. It is a valid statement containing values generated by the FVU which indicates that the file has been successfully validated through the FVU. No modifications should be made in the upload file (.FVU).
