In the mapper there are 2 new fields, From Occurrence and To Occurrence.
The entries for these should be in the form of number of occurrence (character to test). For example:
The initial string is:
9100 HWY 114^TS BSX 72^NEW YORK^TN^38374^WSA
To mask 9100 HWY 114, the first occurrence is left blank and the to occurrence is 1(^).
If you wanted to mask NEW YORK, the values are:
FROM OCCURENCE : 2(^)
TO OCCURRENCE: 3(^)
Please contact Support for the version of Fast Data Masker that contains this new functionality (FastDataMasker-184.108.40.206.zip or greater). Please note that it should be in the next GA after TDM 4.4. As is common practice, please verify with Support that this fix made it into the next GA after TDM 4.4.
