Mapping lookup concept in SAP PI

Hello experts,

I am new to this mapping lookup concept in SAP PI. Can anybody explain me the basic idea and the scenario in which this mapping lookup can be used?

I referred this below link but not able to understand exact meaning and purpose of mapping lookup in SAP PI. Also would be helpful if any scenario is used an example for the explanation

Thank you!

    Hello Omkar,

    Lookup is used to fetch values from external system in to the mapping.

    There are possibilities.

    1.RFC

    2.JDBC

    3.SOAP

    Even file lookup is possible I guess.

    For example you have customer number you wish to pick customer name, you can make a RFC lookup from mapping and fetch the values and send it to target.

    Check the below link

    Hi Omkar,

    The lookup concept is when you need a value or a set of them at mapping level. For example you have a file and you want to send their values to an ECC but you have in an external DB or a third system a set of values to complete the information originally in that file, then at mapping level you can access to the with the lookup. For example you have a second codification for materials in a third system and you want to have in in the ECC endpoint these values and in the file you have one codification, in that third system you can have the union between the source and the ECC system codification.

    Regards.

    Hi Omkar,

    Mapping lookups are used to fetch or enhance business data that is not present in the original message.

    In its strictest sense (as intended by SAP), it should only be used in retrieving data. 😊

    Hi Omkar,

    Lookups used to access values in a back-end system when the mapping program is executed (runtime). By using a mapping lookup, a mapping program can call functions from other application systems while a mapping program is being executed.


    please, have a look of RFC lookup step by step process. you will get clear idea about this.
