Content Type "Item", used in Custom List, comes by default with the column "Title" in it. However in many cases, the name “Title” is meaningless to the purpose of the list. (in some cases the type of column might not be appropriate too).
I shall create a Custom List that contains a list of clients (it will be used in conjunction with a Lookup column (in various subsites’ libraries). The list shall contain the columns “ClientID”(a text like XYZ123), “ClientShortName” (a text like ABC), “ClientFullName” (a text like "ABC-Dummy Limited"). The Custom List and the Columns will be created in the top site of the Site Collection.
The root question is: Shall I rename “Title” to my own name for example “ClientID” (to fit the purpose of my list, ie “ListOfClient”) or shall I hide “Title” (HowTo hide Title column in Custom List) and add my own column for example “ClientID”? What are the consequences of both choices?
Then come the Lookup column that will be used in the document library to supplement a file with additional metadata. For a user experience that metadata shall be representing the ClientID. I would naturally name the corresponding Site Column “ClientID”. Dilemma: There is already a column “ClientID” (either the renamed “Title” or my own column “ClientID” used in the Custom List). Both have the same name but are indeed a different column for a different purpose. The practical way I found to solve this is to name the column used in the Custom List “_ClientID” and create a Lookup column “ClientID” (that points to the _ClientID of the Custom List “ListOfCLient”).
Is there a more elegant way to do it?
