Difference Between Fix Value and Value Mapping?


Can anyone explain me the major diiference bewtween Fix value and Value mapping with example?




Fix Vlaue and Value Mapping:

Fix values, value mapping are standarad functions available in Graphical mapping.

Fix values:

Fix values table will be created internally in IR, and define values for field mapping.

this function generally used for fixed value transfermations during message mapping based on key values.

Value mapping:

Value mapping table wil be created in ID and maintain values in value mapping table for value transfermations during message mapping.

You use the value mapping function to map different representations of an object to each other. You save the mapping rules for

different objects in a value mapping table.


Fix value function is used when your source field may contain certain set of values for which you want to produce values at target.

for example,

Country(Alphabetic) Country(Numeric code)

Source Target

IND 001

AUS 002

GER 008

For above mapping between source and target you can write fix value function,and in fix value function you specify source value as key

and value as target in the table

The main difference between fix values and value mapping is:

1. Fix value deals with defining mapping table at design time that is in IR whereas for value mapping

you need to specify this mapping table in ID.

2. Value mapping can be reused by specifying same party and agency but this is not the case with fix \


Hope this clears you
