Final answer:
The RBL (Requisitioning Objective Level) may be less than the approved minimum or fixed level during emergencies and unforeseen contingencies, as well as during budget constraints and fiscal reviews. d. During budget constraints and fiscal reviews
Step-by-step explanation:
The two instances where an RBL (Requisitioning Objective Level) may be less than the approved minimum or fixed level are during emergencies and unforeseen contingencies and during budget constraints and fiscal reviews.
During emergencies and unforeseen contingencies, the RBL may be lowered temporarily to address the urgent needs of the situation. For example, if there is a sudden increase in demand for a particular product or service due to a natural disaster, the RBL may be adjusted to ensure an adequate supply.
Similarly, during budget constraints and fiscal reviews, organizations may have to make budget cuts and reduce their spending, which can lead to lowering the RBL. This is done to align the procurement process with the available resources and financial constraints.
