I am receiving a warning message when attempting to configure SSCUI ID 102501 for PO Accruals. I am attempting to assign a threshold variant to allow for review of accrual amounts. However, I am unable to assign a threshold variant to any of the item types (SACCRL, SCSTACT, SCSTPLN) without receiving a warning message. Please see screenshots for warning messages. How does SAP intend for threshold variants to be assigned?
