Accesses configuration details of request types in Demand Management.
PPM supports user data on request types. All defined request type user data fields are represented in MREQ_REQUEST_TYPES view; there is a column for each request type user data field. The column name for each request type user data field is the same as the token name for that field.
A user data field with token name OWNER is defined for request types, to keep track of a PPM administrator responsible for maintaining each request type configuration.
A corresponding view column named OWNER will be present in MREQ_REQUEST_TYPES view:
Name Null? Type ------------------------------- -------- ---- REQUEST_TYPE NOT NULL VARCHAR2(30) REQUEST_TYPE_DESCRIPTION NOT NULL VARCHAR2(240) ... INITIAL_STATUS NOT NULL VARCHAR2(80) RESTRICTION NOT NULL VARCHAR2(30) OWNER VARCHAR2(200) CREATION_DATE NOT NULL DATE CREATED_BY_USERNAME NOT NULL VARCHAR2(30) ...
An SQL query based on this view might be used to determine how many requests were created prior to a configuration change for a particular request type.
For example, a request type named Work Order has undergone a significant configuration change that invalidates open work order requests that were created before the change. Therefore, a report is needed to determine the status of open work order requests that were created before the changes:
SELECT wo.request_id REQUEST_NUM, wo.request_status CURRENT_STATUS, wo.request_description DESCRIPTION FROM mreq_work_order wo, mreq_request_types rt WHERE wo.creation_date < rt.last_update_date AND rt.request_type = 'Work Order' ORDER BY 1;
Notice that you do not have to join the explicit request type name to the MREQ_WORK_ORDER view, because it is already implicit in the view definition—only work order requests are returned from that view.
