@WarrenBelz ,
Sorry for the pestering you in this.
Let me explain the process and what I have done.
I have created an excel file and converted it into Table and stored in a SharePoint Folder.

Next, I've created a PBI report by fetching data from the SharePoint Folder and published the report in a workspace.
In the PBI service I have created an Power Apps visuals containing the Req No. and Item fields to implement the write back functionality (i.e. Perform CRUD operation on the source file).
In the Power Apps I've imported the source file via Excel Online (Business).
Note: All the columns are are text datatype.
Please refer the below image for the Power Apps I'm trying to create. Highlighted formula in the Edit form is causing an issue.
My objective is to display the data selected data in the gallery into the edit form

Thank you @WarrenBelz , for being so patient and helpful. Let me know if you need anything else.
