Hi Balraj, Vigneshwaran ,
Welcome to Microsoft Q&A platform and thanks for posting your query here.
As per my understanding, you are trying to pass the key File as a parameter instead of passing the value directly in the linked service. Kindly let me know if my understanding is incorrect.
For the properties within linked service, which do not have 'Add dynamic content' option, you can try parameterizing it using the Advanced authoring option.
- In linked service creation/edit blade -> expand "Advanced" at the bottom -> check "Specify dynamic contents in JSON format" checkbox -> specify the linked service JSON payload.
- Or, after you create a linked service without parameterization, in Management hub -> Linked services -> find the specific linked service -> click "Code" (button "{}") to edit the JSON.
Refer to the JSON sample to add parameters
section to define parameters and reference the parameter using @{linkedService().paramName}
.
For more details, kindly checkout the following video: Parameterize Linked Services using Advanced section in Azure Data Factory
Hope it helps. Kindly let us know how it goes. Thankyou
