It seems like the date portion of ‘PlannedDueDate’ can’t be updated. Only the time portion can be updated. You are not updating the date from the Workflow are you? If you can you show how VarDate is set that might be helpful.

Hi @Lahirumala de Mel 

This is not true as I have another workflow that can update this date completely fine.

I have tested this workflow multiple times and it works. The only issue is the other workflow, which has the exact same call. The only difference is that the input for the date in this call is for the wanted delivery date, and the input for the problematic workflow is varDate, which I define in the following:

var wantedDate = new Date(execution.getVariable('WantedDeliveryDate'))
var currDate = new Date()
varDate = new Date()

if (wantedDate.getTime() > currDate.getTime()) {
execution.setVariable('varDate', wantedDate)
} else {
execution.setVariable('varDate', currDate)
}

varStrDate = varDate.toJSON().substring(0,10);

varStrDate += '-00.00.00.0000000'

execution.setVariable('varDate', varStrDate);

The Workflow team at RnD tried this out but it seems to give the same result in postman as well. This seems to be related to the business logic performed in the API. Might be helpful to understand how the validations are handled in the API. I’m afraid I’m not the person to comment on that.

Hi @Lahirumala de Mel 

Did you ever bring this up to RnD on how to handle this?

Thanks,

Hi @Lahirumala de Mel 

A workaround that is working for us is to change the planned delivery date, which indirectly changes the planned due date without modifying the wanted delivery date (which we dont want to change).

Thanks,
