Clarity PPM On Premise

Issue/Introduction

Allocations can be lost when XOG write is performed to update some allocation segments (not all) for a resource.

Steps to Reproduce:

  1. Add a resource to a project team with one year duration, say from January to December 
  2. Set Work Effort = % Availability
  3. Set %Default Allocation to 0%  
  4. XOG in 30% allocation data for April; XOG is successful and data is correct  
  5. XOG in 40% allocation data for the month of July and August Only; do not include April
Expected Result: July and August data get updated with 40% and April allocation data is intact
Actual Result: July and August data get updated with 40% but April allocation data has been deleted

 

Cause

  • This is working as designed.
  • XOG update of allocation cannot be partial, all allocation segments must be present in the write file. 

Environment

Release: All Supported Releases
Component: Clarity PPM XOG

Resolution

Best practice which will prevent this issue:
  1. Perform a XOG read first and update the file with any needed change
  2. Then use the same file to XOG write back to Clarity PPM.
  3. This will prevent data loss or corruption.
