How to generate or get key file for released reports?

Dear Experts,

I was finally able to find the program RCVDCREO with which mass download of MSDS seems possible. However Mass download was needed to comply with Chemtrec regulations and sending these MSDSs to chemtrec ftp after downloading it from SAP. Chemtrec wants a key file for each MSDS and these MSDS are almost 40,000 in number. No idea how to create Key files for them in the below mentioned format.

DTY =SDB

SID =000000000006

PRN =IS 279 496 US SanitIP red PP25KG

STA =V

LAC =D
