Create PDF/A documents

Dear,

currently we create document in SAP HR with Adobe Life Cycle designer. (pdf based print). This works fine.

Now, I want to save these documents as PDF/A documents.

Is this possible?

Can someone tell me which parameter I have to set and where I have to set it?

(remark: when I create a document manually via Adobe professional I use SAVE AS PDA/A)

Thanks for an answer.

Erwin
