MB-310 Manage Budgeting Practice Question
A Fabrikam controller creates a budget transfer in the budget register. The transfer moves 50,000 from the Operations budget account to the Marketing budget account. Both accounts are under budget control with the same budget model and budget cycle. After posting the transfer, the controller notices that budget control availability for Operations decreased, but Marketing availability did not increase. What is the most likely cause?
⚠ Common exam trap
The trap here is assuming that because both accounts are named in budget control, every dimension combination on a transfer line will automatically match the rule.

Correct answer & explanation
✓
The transfer line for Marketing used a budget class of Transfer In, but the budget account's dimension combination did not match the budget account defined in the budget control rule.
Budget control matches register entries to rules by the budget account dimension combination. A transfer-in line whose dimensions do not match a budget account in the rule is not counted toward Marketing's available budget, while the transfer-out line that does match reduces Operations. Verifying the dimension combination on the transfer line against the budget control rule resolves the discrepancy.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The budget transfer used a budget register entry type that is excluded from budget control.
Why it's wrong here
If the entry type were excluded from budget control, neither the decrease for Operations nor the increase for Marketing would appear in availability. Since Operations availability did decrease, the entry is clearly included in budget control. An excluded entry type would leave both accounts unchanged, so this does not explain the asymmetric result.
- ✗
The Marketing budget account is not included in the budget control rule's budget group.
Why it's wrong here
If Marketing were not in the budget control rule's budget group, the transfer would not affect Marketing availability at all, but it would also not be checked against Marketing's budget. However, the scenario says both accounts are under budget control, which contradicts this. The asymmetric result is better explained by the dimension value combination used on the transfer line, not by group membership.
- ✗
Budget control checks only decrease entries, so increases are never reflected in availability until the next budget cycle.
Why it's wrong here
Budget control evaluates both decreases and increases. Increases such as transfer-in entries and original budget entries reduce the consumed amount and therefore increase available budget. The claim that only decreases are checked is incorrect and would make budget control unusable for transfers and revisions. This is not the reason Marketing availability stayed unchanged.
- ✓
The transfer line for Marketing used a budget class of Transfer In, but the budget account's dimension combination did not match the budget account defined in the budget control rule.
Why this is correct
Budget control matches budget register entries to budget control rules by the budget account's dimension combination. If the Marketing transfer line carries a dimension combination that does not exactly match a budget account included in the rule, the increase is not recognized for availability checking. The Operations decrease still matches its rule, producing the asymmetric result described.
