Negative OptionSet value

Posted on by alireza.majma

Hello,

I have a question regarding OptionSet Value

We are using API to connect Dynamics and importing data to our system,

It is obvious that OptionSet value should be a positive number but we received -1 as OptionSet Value.

We know it is an invalid value and it should be ignored and consider as null.

My question is,

where this value comes from . how it was populated. is there and special scenario that Dynamic fill option set with -1

I appreciate your help in advance

from what you are describing to me looks like you are connecting to a custom API and not directly to Dynamics API.

Probably the custom API returns -1 under certain conditions, afaik it's not possible to receive a negative number for optionset values when using the OOB Dynamics API.

Can you please check if the CRM table contains the value as -1 in the Database ? You can use SQL4CDS in XRM Toolbox www.xrmtoolbox.com/.../

you can run a select query on the table in question and check what value is stored there (I will be surprised to see a -1 value stored as Optionsetvalue in CRM though)

Hello.

Please check the API which is returning the -1 value. You should check if optionset value is not set or null

I know this is an older post already, but I currently experience the same issue and it causes a problem when using Custom Forms showing a 'Invalid Data from Network' message.

I found that indeed the OptionSet can have a negative '-1' value based the user selecting/reverting to the '--select--' option in the default OptionSet Control, presumably when a user tries to clear the selected value. But the '--select--' is not part of the metadata configuration and there is no setting that will allow us to disable the '--select--' option.

In the end this does not result in a critical issue for this implementation, everything works as expected, only the message is shown when a Custom Form with a grid (gallery) is displayed. The value in the gallery showing the value for the OptionSet as a text value is blank as to be expected. Setting the OptionSet value to an actual OptionSet value will resolve the issue. Using a workflow to 'clear' the value (value is null) will also resolve the issue.

If anybody has a suggestion on how to suppress the 'Invalid Data from Network' message without difficult work-arounds that would complicate future maintenance let me know.
