Hi acar atmaca
Thank you for your reply, I have resolved the requirement.
A deeper study on this technology, I will refer to your blog.
My solution is:
1, create a QR CODE in TCODE SE73, examples of reference online
2, copy a PROGRAM RSPO0031 (SE73 EXECUTE PROGRAM) is derived from the TCODE SE73
3 using RSPO0031 form brltest_preview except print part (sapmssco's form)
4, rewrite the form brltest_preview , add export bitmap file part
