Article summary

The following table provides a list of wildcard characters(used to define complex translations) allowed when defining translations along with a description of each.

Wildcard CharacterUsage PatternActionDescription

%

123%

Allow

All source segments beginning with 123.

%123

Allow

All source segments ending with 123.

%123%

Allow

All source segments containing 123.

123%%

Deny

More than one ‘%’ not allowed in sequence.

?

123‌?

Allow

All 4 digit source segments beginning with 123.

?123

Allow

All 4 digit source segments ending with 123.

?123?

Allow

A 5 digit source segments containing 123 in the middle.

123??

Allow

Multiple ‘‌?’ are allowed in sequence. All 5 digit source segments beginning with 123.

~

100~200

Allow

All source values from 100 to 200 (both numbers inclusive).

~300

Deny

‘~’ is not allowed as the first value in a source definition.

500~

Deny

‘~’ is not allowed as the last value in a source definition.

200~100

Deny

To value must be > than From value.

100~200~300

Deny

Multiple ‘~’ not allowed in a single source definition.

100~~200

Deny

Multiple ‘~’ not allowed in a sequence.

100~??

Deny

‘~’ cannot be used with any other wild card character.

%~100

Deny

‘~’ cannot be used with any other wild card character.

%

100%? or 100?%

Deny

'%’ & ‘‌?’ cannot be used In a sequence.

%100?

Allow

All source segments containing 123 in the middle and one character after.

?10%1

Allow

All source segments containing 10 in the middle and one character before and ending in 1.

If an incorrect combination of wildcard characters is used in Translation Lines, exceptions are generated when you save.

The precedence of wildcard characters for applying Translation Rules is %, ~, ‌ and specific\exact character match. This means the system will first apply % to all applicable Translations, followed by ~, ‌ and exact character match.

In Practice

Translation lines are defined with wildcard characters as follows.

Source Segment

Target Segment

  • 10%

  • 1010

  • 1000 ~ 1999

  • 2010

  • 10‌?

  • 3010

  • 1050

  • 4010

In data loads, the source segment is automatically mapped based on the Translations. Each time the Translation Rule is applied, the previous values for Segment Mapping are updated with the latest values.

  • 105

  • 1010

  • 3010

  • 3010

  • 1004

  • 1010

  • 2010

  • 2010

  • 1050

  • 1010

  • 2010 

  • 4010

  • 4010

In Practice

Translation lines defined with wildcard character ‌'?':

Source Segment

Sub Account

Target Segment

  • 101

  • 2001

  • 1010

  • 1??

  • ???

  • 2010

In data loads, the source segment is automatically mapped based on the Translations. In this case, because line #1 is more specific that line #2, Source Segment 101 is mapped to 1010 instead of 2010.
