Answer 1

There is a lot of difference between fixed value mapping and Lookup:
Fixed value mapping is used when you need to populate the some differnt target value based on some inpur value.
Take example
I have used fixed value M:
My input is ABC
Now for this input I wanted to poupulate some different values.
Suppose when A comes in File it should map the target value to America.
When B come it should map to Belgium
and C -> California
Now come to Looup:
What is Lookup and why we need:
Within an XI mapping it is a common requirement to be able to perform data lookups on-the-fly. In particular, there may be a need to look up some data that is maintained in an R/3 application.
In the error handling topic we have seen the different validations which need to be performed on file. This can be done through Lookup.
Some use cases:
• Look up material number from table MARA.
• Look up cost center budget.
• Look up employee information.
• Look up unit-of-measure (UOM) information from table t006a.
• Lookup for raising an alert.
The purpose of the lookup may be:
• To perform application-level validation of the data, before sending it to the backend.
• To populate fields of the XML document with some additional data found in the backend application.
This is a form of value transformation.
The "value mappings" offered by XI are not adequate in this case, since the data would have to be manually entered in the Integration Directory.
There are two ways in which we can do lookup:
• Call lookup method from GUI mapping.
• Call lookup method from XSLT mapping.
I think u got ur answer
