Duplicate Business Objects Which Should be Unique in P6 Can Be Created Through Web Services or the Integration API

(Doc ID 2105464.1)

Last updated on AUGUST 28, 2017

Applies to:

Primavera P6 Enterprise Project Portfolio Management - Version 8.3.2.0 and later
Primavera Web Services - Version 8.3.2.0 and later
Information in this document applies to any platform.

Symptoms

When creating new business objects using P6 Web Services or the P6 Integration API duplicates can be created when running multiple instances of the application. Ids for business object like Projects and WBS must be unique in P6, but when running multiple instances of a P6 Web Services or a P6 Integration API client application duplicates are getting created in the P6 database. 

Duplicates can also be created when the client application is multithreaded. 

STEPS
-----------------------
The issue can be reproduced at will with the following steps:

  1. Write code that adds Projects and WBS levels. 
  2. Run more then one instance of the code simultaneously.
  3. Notice that duplicates are created
