"operation not allowed" when I try to delete on table

I need to delete some users in the CMDB’s but it show the following error:

ERROR: CM: operation not allowed: you cannot execute DELETE on this table
CONTEXT: PL/pgSQL function _cm3_trigger_card_prepare_record() line 37 at RAISE

When there are more than 1 row in the result to select, we can delete the rest of the row except the first

In this case, first row show there error when I execute the delete

Could you explain me why happen it?
