IDO REST API – Forcing Use Fixed Schedule to False in Current Operations

c-zuniga

Hello,

I’m working with the Current Operations form via the IDO REST API, and I’ve run into some behavior I can’t reconcile with the documentation.

Specifically:

• When I send UseFixedSched/UseOffsetHrs = false in my API payload, the field is automatically reset back to True when I retrieve the record (RefreshItems).
• I attempted to control this by adjusting JshSchedHrs/JshOffsetHrs.
  • If I set it to -1, the input mask rejects it.
  • If I set it to 0, the system resets it to 0 and still flips Use Fixed Schedule back to True.
• In the UI, I can clear the checkbox manually, but I haven’t found a way to achieve this through the API.

From the documentation I understand:

• If Use Fixed Schedule is selected, the Scheduler Rule is forced to Fixed.
• If it’s cleared, the rule should revert to Per Piece.
• Outside operations always enforce Use Fixed Schedule = True regardless (though in my case, the work center is not outside).

Questions:

• Is there a hidden dependency where FixedSchedHrs or another field forces Use Fixed Schedule = True, even if I send false?
• Through the IDO REST API, is there a way to truly “clear” the FixedSchedHrs field (null it out), rather than sending 0?
• Has anyone successfully managed to keep Use Fixed Schedule = False when creating/updating operations via the API?

Any guidance or confirmation would be greatly appreciated.

Thanks,
Carson

Note that the input mask for JshOffsetHrs is >>>>9.99, meaning the field accepts up to five digits before the decimal and two after, but it cannot be Null or negative.

However, UseOffsetHrs is derived as such:

CASE
WHEN JshOffsetHrs >= 0.00
THEN 1
ELSE 0
END

It seems impossible to disable UseOffsetHrs via API?
