FCCS Forms YTD Input Accumulation Issue When Months Entered Out of Sequence

In FCCS, YTD input forms are designed to accumulate values across months. This works correctly when data is entered in chronological order (January → February → March, etc.). However, if months are entered out of sequence, the system recalculates based on the latest entry and then adds prior months afterward, which can lead to inflated balances.

Illustration:

• February input = 25,000
• Later, January input = 15,000
• Result: February now shows 40,000 instead of the 25,000

Observation:
We have already advised the client to follow chronological month sequence when entering YTD inputs to avoid this behavior.

Query:
Is there any sub-variable, configuration option, or system setting available in FCCS to prevent YTD accumulation errors when inputs are entered out of sequence?
