Then you need to submit the form first before attempting to read the contents of the uploaded file. This is easy enough to do - just make it 2 separate forms; the upload on the start form, and the output on the subsequent User Input Task.

in this screenshot the file has just been uploaded but is not yet Submitted into the system. you'd need to submit it (usually via submitting the form in a process task), and only then call "read excel sheet" on it. some of this was already explained in earlier replies.

That's because you are trying to read a document which is not yet stored in Appian ,Initially it's gonna get stored in Temporary folder . Have a look into my reply where i explained how to read a document in the same interface.

I don't know whether this will work - the Update Constant Smart Service requires a reference to the constant, I don't think you can use a Constant Name instead.

Edit: sorry I was wrong. The smart service also accepts the constant's ID (as in, its integer-based environment-specific object ID, similar to a Process Model ID).

Getting the Constant's ID isn't super easy though - you have to use "get constant or rule UUID by name", then the "get content object details by UUID" function and extract the "ID". The quick-and-dirty expression, which could go directly in the "constant" field of the Update Constant smart service, could look like this:

extract( getcontentdetailsbyuuid( getconstantorruleuuidbyname("MY_CONSTANT_NAME")), "Id: ", ", Parent:")

You'd simply replace "MY_CONSTANT_NAME" with the actual constant name. You'd need to be sure the constant name actually exists, otherwise I expect the node would error.

(If anyone has an easier way to do this, i'd love to hear it.)

Yeah, I can understand that and I don't think so that any smart service is there to create constant.

bisheswar01 — Wed, 07 Aug 2024 10:01:49 GMT

what the scenario is , I will check for a constant if it is there in my application or not . If there is no constant then create a new one .

how to achieve this ?

RE: fetch data from uploaded file.

Prasanta Paul — Wed, 07 Aug 2024 09:38:51 GMT

I don't think so, you can update or increment the constant.

bisheswar01 — Wed, 07 Aug 2024 09:34:30 GMT

there is another question also . Is there any plugin or smart services in appian for creating constant ?

I searched in process model but did not get that .

If there is any can you please give me a reference to read more about that ?

Smart service

Bhargavi Prakash — Wed, 07 Aug 2024 00:50:31 GMT

Hi bisheswar01
This is Appian provided smart service you can check in process model , we need to provide two inputs for this constant one is name and the other is with what value we are going to update, please keep this node in a swim lane and the assignment of it should be run as who ever designed the model to avoid security issues.

David Jimenez — Tue, 06 Aug 2024 22:09:25 GMT

It's an smart service that you can use in your PM for updating constant values..

Do it as Bhargavi Prakash explain in his message...

When updating the constant value, take care of permissions

bisheswar01 — Tue, 06 Aug 2024 18:07:19 GMT

can you please explain or give me a summary of using update constant plug in ? Or any link to understand that

RE: fetch data from uploaded file.

Bhargavi Prakash — Tue, 06 Aug 2024 14:58:20 GMT

Hi bisheswar01

1) Provide a interface where user can update the excel file

2) Once user click on the submit button you can read the excel file using the plugin

readexcelsheet(
excelDocument: cons!OBJECT_LIST_TEST,
sheetNumber: 1,
startRow: 1
)

it return the ExcelSheetResultSet which contains the data in the excel sheet and success response.

3) You can use the ' Update Constant ' plugin to update the value of the constants. use the above result set and call this node as MNI for each value it should update the data.

Hope its clear.

Thanks,

Bhargavi P.

How you want the interface, you want it as a Startform ? Or standalone userinterface. If it's standalone interface where you gonna upload a File , use SubmitUploadedFiles (You can't use this in startform or task) to save the file into Appian and use readexcelwithPaging which comes with Exceltools plugin to read the uploaded file contents and show it on editable grid . After editing give user a option to run a processmodel to update the constant.

hi bisheswar01 Initially upload a file from UI, save the data of the file in a pv!variable, and pass that pv to UI from the same process model. show the data the UI in a grid format,make the edits for your data and then submit and save the data
