Multiple Concrete Class pointing to one DB Table Giving Error on Test Connection. {PEGA 7.4}
Hi All,
We are using Buliding Application in which we have multiple Concreate Class which is pointing to one database table.
The following is working fine when we try to push data and retrieve the following,
however if you try to do test connection form the Class rule from it will give the following error.
Error: Class ClassName1 is mapped to table Name in DBName.
This is an Obj-external class. You may access the class with Obj- activity methods.
Issues:
External data table TableName in database DBName has more than one concrete class mapped to it; these classes include ClassName1 and ClassName2
Need to Understand why this is throwing this error, as far I understand we create a concrete class it just need a table in Database.

Hi ,

Do you see the same error while you click Test Connectivity from both the class rules? How did you create the Class mappings to database table? Is it through External Database Table Class Mapping Wizard?

You can also try to trace while Testing Connectivity to check where it is breaking.

Regards,

Waseem Khan

The error message doesn't appear to suggest that there's an error (apart from being prefixed with "Error")

Do both classes have a pxObjClass and is the associated with a column of the same name?

For the Exposed table we cannot use pxobjclass column as directly reference and thus we have processing class column which is similar to pxobjclass.

Please let me know how I can refer pxobjclass property to the exposed column as its giving error that total exposed table cannot use px,py,pz property.
