@Radoslav Magal Were you able to resolve this? You will need a full studio developer license to edit a BAPI based script in the Direct Module.
The Direct scripts eventually are TXR filetype, so you were able to run it with a transaction license.
If you want to upgrade to full studio, please contact your account executive to get pricing. Full studio gives you access to transaction, query and direct modules.
hi Jayasri, thanks for offer, I did it with transactional script(delete all and recreate only those I needed). Thanks @Vanessa Kutasi for explanation.
