OpenText VIM transaction /OPT/AR_COA read only

Dear experts,

I have a very basic question regarding the display of the COA table in VIM.

My customer is using the transaction /OPT/AR_COA to maintain the coa table. To support them, I need access to the COA settings in P-System, but only with display rights.

Is there a transaction to display the COA table?

I´ve created a role which contains the transaction /OPT/AR_COA and I´ve set all authorization objects regardings this transaction to activity 03, but in testing it is still possible to enter changes. Do you have any experience with this?

Is it maybe possible to get the information from tables with SE16?

thank you,

Matthias
