FDM.4:4.3 - Establish what actually occurred

Inspect the evidence relevant to that rule and effect. Match the parties, arrangement, amount and occurrence. Distinguish an instruction from its execution and a provider’s local result from the recipient’s result where those differences matter.

Retain the dates needed to interpret the action: occurrence, effective date, posting or actual availability can differ. Obtain only the dates that can change the present answer. Evidence sufficient for “instruction received” may be insufficient for “recipient can use the funds”.

If sources disagree, first compare their subjects, dates and meanings. Then investigate the remaining factual discrepancy. Do not select a source as decisive merely because its application is the most familiar one.
