Archive Employee for Info type 0008

Hi Experts.

I have a requirement liek, i need to archive the personal number for info type 008.

We have an Object PA_LDOC. The write program is RPAR3W00.

I need to modify the write program, which should accept the data from flat file to create the record and archive the created record for Info type 008.

Please let me know how can i go a head, since i dont have parameters for personal number and infotype in the selection screen.

Thanks,

Sriram.
