Fast formula not work when add code to get holiday information when add time card

Hi All,
I tried to add a formula to my time rule like follow:
1.Only 8 days is allowed everyday.
2.Weekends do not check about the hour limitation in step1.
3.Public holiday do not check about the hour limitation in step1.

I already achieved the 1 and 2 step refer standard formula:ORA_WFM_TER_PERIOD_MAX_WITH_MSG_MEASURE_FORMAT_OPTION_AP and it works fine when adding time card.
I added following code for step3, after I added it and update the rule set/processing profile settings. The fast formula not trigger at all (including the step 1 and 2) and Time card saved successfully when adding time card.
