Cause

  • The error on RBP mainly occurs due to configuration issue in the data model specific to company instance;
  • Any kind of misconfiguration may lead to such error message;
  • For example - Two elements in data model are having same id or few fields are expected to have at least a value which is not in place.

Resolution

INSTRUCTIONS FOR PARTNERS:

  • Review data-model configuration for elements with duplicate ID's note that during the data model importing in provisioning, it will check if there are duplicate elements ids, however in EC BCUI page ‘Manage Business Configuration’, it will not check if there is any duplicate id when you try to Create.
  • Check if any recent changes have been made to data model configuration either from BCUI or data model directly this may help identify the configuration quickly. 
  • A common mistake made would be to have a background-element and a standard-element with the same ID in the data-model. Example:

    • One standard element:
      <standard-element id="talentPool" required="false" matrix-filter="false">

    • Further down, a background-element with same ID:
      <background-element id="talentPool" type-id="60">
  • If a duplicate element ID has been found, amend one of the ID's and re-import the data model.

Note that background-element with id ‘Competencies’ is reserved for Talent Search Field and if configurated as a background element this will also generate an assertion failed message. 

CUSTOMERS WITHOUT PARTNERS:

  1. Customers can check for duplicates from within BCUI " Manage Business Configuration directly.
  2. Check if any recent changes have been made to data model configuration either from BCUI or data model directly this may help identify the configuration quickly. 
  3. If you face issue locating the issue from within BCUI please open a support cases. 
  4. Ensure to include the error details and a screenshot of this issue. Specify if any recent changes were made to BCUI.
  5. As the error could be very specific to the instance, it is mandatory that SuccessFactors support staff reproduces the issue;
  6. Support staff will review internally and work with the respective engineering team to identify the root cause if required.
  7. Once analysis is completed we will inform customer about the error in configuration & changes required.
