Why are the Changes Made to the RMOATHTB Security Table not Taking Effect?
If there is a modified CA Deliver RMOATHUX exit in use, its contents will override anything in the RMOATHTB security table, which can appear as the table changes not taking effect.
If you reset the RMOATHUX exit to what was originally shipped with the product, then the RMOATHTB security table will take full effect.
