ENUMERATION in SAP PI 7.1
Issue: While consuming a Web service that is provided by SAP PI 7.1/7.0, external application program that consumes the web service need to get the values for particular field restricted with list of values.
For example: For Country_Code field in outbound structure I need restricted 20 country codes (where my business is operative) and I want Country_Code field value to be in CAPs. Like IND, USA, AUS etc…
Consider creation of a customer in External System, and it is using web service generated by SAP PI, and updating customers in SAP ECC. The user must select only restricted company code values or a reconciliation account provided in the drop down as per their company.
In order to achieve this feature, PI 7.1/7.0 has provided us with data type enumeration in XSD Editor while creating Data Types.
Definition: The most abstract definition of an enumeration of a set is an exact listing of all of its elements (perhaps with repetition).
- W.r.t SAP PI, enumeration restricts the value range to a set of individual areas .The values must be separated by blanks or commas in the XSD Editor.
Implementation of enumeration in PI:
We Implement Enumeration in “Data type” level under Details column in the XSD editor or simply press the button provided in the XSD Editor. Data type enumeration is given below.
- Data Type Filed à Details à enumeration.
At the corresponding field level select the details column wherein enter the required enumerated values separated by a space or a comma as below.
Once we consume web service generated on this data type Company_Code field will shows a drop down list that holds enumerated values i.e. the restricted values are displayed as follows:
Here we have used Microsoft InfoPath as Web Client.
A drop down list is appeared with all restricted filed values for selection by using Enumeration in SAP PI 7.1
