Peoplesoft Attachment

Hello,

I have written peoplecode to generate attachements to a physical storage location using the code below. The problem is if there are attachments with the same file name, the already existing ones would get over written on the file server. Is there anyway to generate unique file names for the files generated?

&UC_Rs = CreateRowset(Record.UC_TV_RQST_ATCH);
&UC_Rs.fill("WHERE UC_TV_REQ_NBR = :1 AND UC_TV_ATT_TYPE='PD'", &uctv_req_nbr);
For &i = 1 To &UC_Rs.activerowcount
   &UC_Attachsysfilename = &UC_Rs.getrow(&i).getrecord(Record.UC_TV_RQST_ATCH).ATTACHSYSFILENAME.value;
   &UC_Attachuserfile = GetEnv("PS_SERVDIR") | "\files\PD\" | &UC_Rs.getrow(&i).getrecord(Record.UC_TV_RQST_ATCH).ATTACHUSERFILE.value;
