Mask Format

Mask Format

Configure a mask format to limit each character in the output column to an alphabetic, numeric, or alphanumeric character.
If you do not define a mask format, the
Data Integration Service
replaces each source character with any character. If the mask format is longer than the input string, the
Data Integration Service
ignores the extra characters in the mask format. If the mask format is shorter than the source string, the
Data Integration Service
does not mask the characters at the end of the source string.
The mask format contains uppercase characters. When you enter a lowercase mask character, Test Data Manager converts the character to uppercase.
The following table describes mask format characters:
Character
Description
A
Alphabetical characters. For example, ASCII characters a to z and A to Z.
D
Digits. From 0 through 9.
N
Alphanumeric characters. For example, ASCII characters a to z, A to Z, and 0-9.
X
Any character. For example, alphanumeric or symbol.
+
No masking.
R
Remaining characters. R specifies that the remaining characters in the string can be any character type. R must appear as the last character of the mask.
