Hi Goutam & Rawish,
I went to try what you have suggested, but I haven't had luck not sure what other details I can provide to help, but perhaps the below assists?
If I find the entity in the customizations section and try to change the forms' managed properties, it's already set to true.
The entity appears to be "Solution History Data Source" and the form appears to be the card. I'm guessing this because I went to try what Rawish suggested, but couldn't exactly follow all the lingo in the article.
From the failure log: 01:49:11.12 Form msdyn_solutionhistorydatasource Solution History Data Source Solution History Data Source Failure 0x8004F026 The evaluation of the current component(name=SystemForm, id=bbc892b7-896b-480c-ace7-fdf69340d215) in the current operation (Create) failed during managed property evaluation of condition: Managed Property Name: isparentcustomizable; Component Name: SystemForm;
From the customizations XML file: but I have not idea which one two switch so I didn't touch.
