Resource allocation not generated for a Resource Assignment

I am working on an issue where a Resource Assignment is missing Resource Allocation data which should be there as per the OOB functionality . I need to understand if there is a way probably a fix script to generate Resource Allocation for Resource Assignments which are missing allocations ? A quick help would be much appreciated ?


Thanks & Regards,

Subham Shaw

Hi @SUBHAM_SHAW_SN ,

By design, when a Resource Assignment is created, the system should automatically generate the corresponding Resource Allocation. If allocations are missing, it usually indicates either a data integrity issue or a customization interfering with the OOB process.

There isn’t an out-of-the-box fix script provided by ServiceNow to retroactively generate allocations for existing assignments. However, you can:

  1. Recalculate Allocations: Try the “Recalculate Resource Allocations” job (available in Resource Management) to see if missing records are generated.

  2. Check Business Rules / Workflows: Verify if any customizations are preventing allocation creation.

  3. Custom Fix Script: If needed, a scripted solution can loop through Resource Assignments without allocations and insert the missing Resource Allocation records. This would need to replicate the logic of the OOB creation process (dates, FTE, hours, etc.). I’d recommend testing thoroughly in sub-prod before applying.

  4. Open a Support Ticket: If this occurs on an unmodified OOB setup, it may be a platform issue and worth raising with ServiceNow Support.
