How do you configure a Time Calculation Rule (TCR) formula and template to enable the TCR rule to display process results and a validation message…

In Fusion Time & Labor, only Time Entry Rule (TER) formulas can raise validation or warning messages that appear on the time-card UI, whereas Time Calculation Rule (TCR) formulas return calculated time attributes.

To surface both kinds of information from one rule, embed (call) a TER formula inside a TCR formula with the Fast Formula SUBFORMULA/RETURN mechanism, pass the TER’s MESSAGECODE and MESSAGETEXT back to the TCR, and expose both the calculation results and the returned message in a custom TCR template. Because the message originates in the TER but is returned through the enclosing TCR, users see a single rule that delivers the process result line and the associated validation message on the Outputs train stop.

B – Reverses the allowed call hierarchy; a TER can’t invoke a TCR and still expose calculation results.

C – Uses two independent rules; messages are shown by TER, not “from the same rule” as required.

D – TCR templates don’t accept a TER template as a selectable parameter; no framework support exists.

E – There’s no “WFM validation utility” callable by a TCR; only TER formulas contain the validation API.
