Problem:
When using the GUI Interface Mapping Toolkit within Net Express to create a Web Service mapping for a COBOL subprogram which will be run as a service, the drop-down list of possible data types is a bit confusing.
The IMTK currently allows you to create mappings between fields in a programs linkage section or within a BMS screen or COMMAREA.
These can be mapped to services such as Web Services, EJB's COM Serrvers or .NET WinForm/WebForm front end.
Resolution:
Please look at the attached table in a Word document format named "COBOL Data Item.DOC".
This will show the best fit selection for a data type from the dropdown list of data types in the Interface Mapping Toolkit.
Although you can choose a different data type then what is used in the sending program and receiving Web Service there is always a chance that if you specify the incorrect type then invalid data might occur or an invalid parameter might occur because of truncation of the data item by moving too large of a value into too small of a receiving field.
