Direct Posting Accounts Not Copied to GL in Another Company Code

Hi,

I'm trying to copy the GL from a company code to a new company code using OBY2. There were 98 accounts in the first company code but I only successfully copied 94 accounts to the new one. I checked the COA and it shows that there are 4 inventory direct posting accounts not copied. Why this happened and how can I fix this? Thanks!!
