Different Publish Paths for Different Forms

Hello Everyone,

I have a BP with a two-step workflow and each step have their own form . I need to have my attachment go in different folder on my DM. For this, I design publish path DE of my forms with different values.

It's working for the first step, but I discover that when I add an attachment on the second form, it will automatically use the value of the publish path DE of my first form.

Do you know why ?

Thank you in advance for your help.

Best Regards,

Thomas
