A parent company could be defined as a large organization that manages and controls smaller subsidiaries. Hotels may want to report on the volume of business associated with a parent company and it's subsidiaries, so therefore will build profiles on parent companies and link the related subsidiary companies. Some hotels may not maintain this type of data. In some instances in IDPMS, the term 'Mother' may be used interchangeably with 'Parent' Parent Companies are not directly linked to a reservation. They are indirectly linked via their linked subsidiary companies. (Company relations linked to the Parent Company)
To create a Parent Relation Profile, go to the Relation menu and select Parent Company.
The following seek window will appear:
The option to seek for an existing parent profile or add a new one is available. To add a new one, select the add icon 
The 'New ' Mother Company window opens;
Name - The Name field is mandatory. Enter the name of the parent relation.
Mail address - Enter the mailing address. This address can be used for billing and confirmation letters.
Visit address - Enter the visit or street address.
Phone, Fax, Website and Email address - Enter applicable data.
Protect -can be checked to protect the profile from any unauthorized changes by an unauthorized user. Only a system administrator (super user) may be permitted to remove the check at a later date. Access is based on access rights set up in menu user access rights. The right is under Reservation Rights - "User can edit relation profile" This profile may still be changed in future if the box is not checked.
Market - is used to link a company to a specific Market type. This is useful if using the Mailing Wizard in IDPMS and the user wants to extract specific companies from the database that are linked to a specific 'market' type. See Market Code for more information on creating market code pick lists.
Source - is used to link the parent relation to a specific market source and is important for statistical data. This is useful if using the Mailing Wizard in IDPMS and the user wants to extract specific companies from the database that are linked to a specific 'source' type. See Source Code for more information on creating source code pick lists.
Memo is used to enter any relevant information about the Parent relation. The memo is for internal notes only. The memo text will not be copied over to individual reservations linked to the Parent Company via the linked company relation on a booking.
Save the changes using the green checkmark. The Parent Relation will then have a unique parent relation number. It will show the 3 character relation prefix used by the property for relation codes followed by MC and a unique number (XXX-MC###)
At the bottom of the relation profile window, there are two fields that show Created and Changed.
Created will identify the user that created the relation profile initially. The date created is also noted.
Changed - will identify the user that made the last change including the date of change.
