I have a documentDownloadLink, when user click on the link, it always calls a white screen and last for few seconds, after white screen disappear, the document starts download. Is the white screen expected? Or can it be overcame somehow?

Can we leverage Appian as the backend for our external application developed using Blazor, enabling access to all Appian resources through APIs, including the standard Appian login, password reset, and password recovery functionalities

Can someone explain why datetext() is returning 2022-11-30 given the input of the date 12/1/2022. I came across this thread which states datetext() is no longer supported however it appears within the latest (24.4) All Functions list within Appian. community.appian.com/.../issue-with-using-datetext-function-in-appian-portals

Hello Community, Following situation: handover didn't go smoothly, so the password for the main Appian Oracle user which holds all tables was lost. The password was changed, and somehow the Data Source for the old configuration was gone in the Admin panel. Not sure how that happened, but I added it on all environments with the correct connection strings again. However, the Data Stores had to be configured anew. This luckily was no problem on Prod, but I am now facing an issue on Dev with a few distinct ones. When I select the Data Source and try to verify, I get this message: "An error occurred while attempting to verify the data store: Type definitions could not be found in the Appian data source for the following type ids: 5504 (APNX-1-4047-008)" So I tried checking the CDTs that are connected to it, and for each one I try I get this error: "HTTP Code: 500 APNX-1-4198-000 Error Evaluating UI Expression Expression evaluation error [evaluation ID = HCBTYGS5

Hello,  How can I download a document that is stored in Appian from an external system?Currently, I am document(documentId, "url") to get the document's URL, then storing that URL to a table. My external system is grabbing that URL and attempting to CURL the url to download the file. An HTML document requesting the user to sign in is returned, so I am assuming that I must authenticate to Appian. Is there any documentation that can be pointed out on this process? I could not find anything in the docs.  Thank you

I am new to the Appian platform and am currently exploring the Appian Portals. I have created a portal, but I am unable to publish it as I am being prompted to add a service account. However, I don't have access to create one. To create a service account, I believe I need access to the Administration Console, but I cannot see it in the menu. Is this limitation due to the fact that I am using the Community Edition? Does the Community Edition not provide access to the Administration Console?

Hi All, I have expression rule which contains HTML Code. How to insert Image into this HTML code which is stored Appian Folder without using HTML Template / converting image into base64 / passing web URL? Thanks, Ganesh.

I am currently using Smart Service "Import Excel to Database".  The process works fine if I upload an Excel file with correct column headers and data values. In the excel file I purposefully changed the data values like changing a date value to a text value XYZ, changing Text value to a date value. When I upload this modified excel file: 1. The process does not error out. Process Model is showing everything as success. 2. The incorrect data did not get inserted. But my question is, how do I catch such data errors? I thought the Smart Service "Import Excel to Database" is going give some information on the errors. Please advise this.  In the real world we will not have perfect data all the time. Hence trying to figure this out. Regards, Mahesh

I am just looking at this rule and find this unsupported function can anyone tell me that what is the behaviour of this function .reduce( update_unsupported(_,_,_),{},{} )what we can use instead of update_unsupported to remove (_,_,_)

I have a process for bulk action in a grid, in which there is a MNI, in each instance it writes records to db. I want all records auto update after user submit without extra refresh. How can I achieve this? Currently only one row can be auto updated, rest of all need a refresh to show latest record

Earlier today I was helping another developer understand an issue involving links using a urlwithparameters() function. They were experience an issue where a datetime passed as a query parameter was reading out one minute behind in the linked interface. When I investigated the issue I noticed that the query parameter was showing as a timestamp; however when I ran some small-scale tests I noticed when I passed datetimes as query parameters they were formatted appropriately (see screenshots for context). Ultimately what we discovered is that their use case they were passing two parameters, one an integer ID and the other the datetime. In my testing I was initially only testing with a datetime. When I included a similar integer parameter I was able to get the odd behavior to replicate. The solution for us was to cast the other parameters to strings. What is more interesting is that the behavior only occurs when the datetime is taken from a record. If I replace the datetime query param wit

I have configured showExportButton=true in my grid, I wonder if it is possible to specify the columns I need for export

We are planning to build an application using Appian that will be used by 5 to 10 users. According to pricing, we fall under the ≤ 200 users category, where each user costs $75. My questions are: Do we need to purchase licenses for each user (e.g., 5 users × $75), or is there a minimum user (threshold) purchase requirement that applies regardless of the actual number of users? If there is a minimum purchase requirement, what is the minimum number of users we would need to pay for?

I have connected to the proctor and confirmed my details related to my exam. My proctor asked me to open the camera video, but the camera froze in between the verification process. The proctor asked me to restart my system but the same error is going on. i have try many times but not able to solve the problem, i did not aware with this error before. than proctor told me to connect to the support for retake the exam due to this condition and problem. can i get a reschedule coupon for it

When I try index({1,2,3},{3,4},"") returns {3,null} whereas index({1,2,3},{3,4},{}) returns {3,1}. Looks like when curly brace is put in default parameter, when there is no 4th index, it goes back to start and picks the first index. i don't think this behaviour is captured in documentation either.

I had exam today due to some reason I lost my Internet Connection and proctor told to me we cant start exam due to inconsistency of my Internet and she marked it Incomplete.I have sent email on Appian Certification and Appian Support to have it rescheduled but I haven't heard anything yet. If anyone help me that would be great.Thanks

I can't find my exact issue, so I'm starting a new thread.  I created two interfaces - one that shows a single survey and its answers in a grid and the user can download the data to Excel. That works fine. Then I made a copy of the interface and instead of filtering on a survey the grid displays ALL surveys and answers. However, when you try to export to Excel, I get the error "Couldn't Download - Network Issue". The number of records is LESS THAN  20 and so it's not a size issue. This happens in the DEV environment. I haven't tried it in the TEST environment because I'm not ready to push my code yet. Any thoughts why? 

A very helpful addition to SAIL programming would be single-line commenting. The current block commenting method creates hassles when commenting and uncommenting chunks of code for troubleshooting, or when nesting comments, should we follow best practice and document functionality with /* Dev Notes */. We are currently unable to block-comment with single /* and */ around a section containing actual comments (nested), the first trailing */ ends the surrounding block comment early. This occurs when collapsing a large section spanning a few pages, and add these 2 lines around the collapsed section, which is sometimes easier than highlighting multiple pages for ctrl+/. Example: /* a!boxLayout( label: "Submitter Info", marginBelow: "STANDARD", contents: { /* Submitter Info */ a!textField( value: loggedInUser(), readOnly: true ) } ) */ Additionally, if you highlight a section containing comments, ctrl+/ to comment all, then ctrl+/ to uncomment all after troubl

Good morning, We have an Appian configuration with three servers. I would like to know if anyone knows whether I can access the log data-metrics/system.csv from the other two servers from any of the three servers, and how I could do it? Thank you very much

I’m currently exploring the benefits of the Appian Instructor-Led Course and wanted to get some insights from those who have participated in it. Specifically, I’m curious about the following:  Does the course provide access to an upgraded instance similar to a real-world production-like environment, or is it limited to the Community Edition for practice exercises? Benefits over the online free course provided other than personalized training

Hi Everyone, I have a use case where I need to get the date difference between two dates ; but using the calender available in Appian. Due to some performace issues, all date differences I am doing in stored procedure and calling the same from Appian to get the value. But If I have to consider Appian calender, how to pass to the stored proc, so it will provide me the correct date difference considering the calender. Regards, Ghanashyam

Hello All I want call Procedure that take more than 300 seconds.   when call it using expression rule the result is (ORA-01013: user requested cancel of current operation) and maximum timeout is 300 second how can I call this procedure?? Is there a plug-in that increases the maximum timeout?

In the Pricing Model of Appian Software, it mentions - This represents the entitlement per application for Standard User, Advanced User, and Premium User. For Platform - Standard User, Platform - Advanced User, and Platform - Premium User, this represents the total entitlement across all applications. What exactly is the difference between a "Platform User" and an "Application User" ? 

Lets say I have an Interface with 2 Dropdowns. Lets call them Dropdown1 and Dropdown2. Both have Values Yes and No. If User selects Dropdown1 with Value Yes, then Dropdown2 should automatically be set to No and it should be greyed out or disabled so that User cannot change it to Yes. Please advise how we can accomplish this. Regards, Mahesh

HI All, Example -- I am forty-five years old. from above text i need to get 45 in integer form. How to achieve this? Thanks, Ganesh.
