Source String Characters

Source String Characters

Configure source string characters to choose the characters that you want to mask.
For example, if you set the number sign (#) as a source string character, it is masked every time it occurs in the input data. The position of the characters in the source string does not matter, and you can configure any number of characters. If you do not configure source string characters, the masking replaces all the source characters in the column.
The source characters are case sensitive. The PowerCenter Integration Service does not always return unique data if the number of source string characters is fewer than the number of result string characters.
The following table describes the options that you can configure for source string characters:
Option
Description
Mask Only
Masks characters in the source that you configure as source string characters. For example, if you enter A and b as source string characters, every instance of A and b in the source data will change. A source character that is not an A or b will not change.
Mask all except
Masks all characters in the source except for source string characters. For example, if you enter "-" as the source string character, every character except for "-" will change.
