How to use setGenric() method on EPMdocument ?

Hi All,

I have created a EPMDocument "TestA" and attach content to it through API.

I want to make this EPMDocument as a "Genric". for that i am using,

.setGeneric(true);   method, but i am getting below error , please help me to solve this.

Exception in thread "main" (wt.pom.pomResource/0) wt.pom.PersistenceException: A persistence error occurred. System message follows:

Nested exception is: (wt.epm.util.EPMResource/364) wt.util.WTException: Family table validations failed. Please contact PTC unless this occurred during a package import. Failures on package import may be due to a compatible generic not being available at time of import.

  at wt.epm.FTValidatorTransactionListener.validateObjects(FTValidatorTransactionListener.java:774)

Thank you,

Vivek
