Thanks.. Gopi...
Sorry, it was my mistake. I mentioned crmt_object_guid instead of crmt_object_guid_tab. I'm getting the data now.
But, the problem is, when raise the DO_NOT_SAVE error, the fields on the view are getting disabled.
How can we display the error message and keep the view editable to allow the user to make corrections?
@Faisal: Can you please explain why we should use CRM_ORDER_READ_OW FM. I've been trying to figure out the difference between these two FMs.
Ans, I still would like to know how the GUID is getting populated before saving the order.
Thanks.
