We have done a setup for an Inventory Organization.
Everything was working fine.
Values were showing everywhere.
We have lot of transactions done in the org also.
But suddenly yesterday when I was trying to open the Organization Parameter form for that specific organization, the form came up as blank and in the bottom the error is Query caused no records.
I have checked data is there in the base table mtl_parameters.
Value is coming for other organizations. Only one specific organization is having this issue.
Even in Examine, I have taken the last query run on that form and ran the same in back end database, I can see all values are there in the database.
But in frontend screen the values are not showing. even organization code also not showing.
Navigation is: Inv Super user --> Setup --> Organization --> Parameter
Have you checked Organization Access to ensure that no one restricted that org?
Or shipping grants and roles?
I think there are quite a few places that you can restrict access.
