Have not seen the case you mention; on the implementation I worked on we had separate files for each OU.
If the cards are only active for one OU, wouldn't it work to create 3 programs and then upload the same file for each? Only those relevant for the OU should upload.
Oracle has created an enhancement request for the same. The program auto creates the card and loads the data in the same OU. We are doing a customization to handle the same.
Lords'm new in this forum, I would entedimento and help from you guys. I'm initiating setting to card credito and ask that me send all documentations initial, the steps to make this settings. Thank you for your attention and espertise of you in the system.
