You use the Member Name box of the Member Name dialog box to enter or edit member mappings for partitions.
You can enter or edit only one member name at a time.
You must enclose in quotation marks member names that begin with a numeral (for example, "100-Blue") and member names that include any of the following characters: ampersand, asterisk, at sign, backslash, brace, bracket, colon, comma, dash, equal sign, exclamation point, greater than sign, hyphen, less than sign, minus sign, parentheses, percent sign, period, plus sign, semicolon, slash, or tilde.
For duplicate members, you must enter qualified member names. Qualified member names are identified in Outline Viewer, in the Member Properties dialog box. If you use the member selection tool to select a duplicate member from the outline tree, the qualified member name is inserted automatically.
For information about advanced, area-specific member mappings, see Defining Area-Specific Member Mappings in Partitions (Optional).
