Records

A service backed record syncs data in batches but its behavior is inconsistent, any idea where to check the logs what exactly its passing for each batch or any api calls its doing to fetch the data during run time?

HI everyone, I’m having a nested CDT that takes quite some times to query data. Thus, I though replacing it with query sync records using relationships between them can be a more time efficient solution. Below is how my record query looks like: a!queryRecordType( recordType: 'recordType!AAA CF Check List Instance SR',filters: a!queryLogicalExpression(operator: a!defaultValue(ri!filterOperator, "AND"),logicalExpressions: ri!logicalExpression,ignoreFiltersWithEmptyValues: true,filters: append({a!queryFilter(field: 'recordType!AAA CF Check List Instance SR.fields.isactive',operator: "=",value: ri!isActive),a!queryFilter(field: 'recordType!AAA CF Check List Instance SR.fields.checkListInstanceId',operator: "in",value: ri!id),a!queryFilter(field: 'recordType!AAA CF Check List Instance SR.fields.checkListId',operator: "in",value: ri!checklistId),a!queryFilter(field: 'recordType!AAA CF Check List Instance SR.fields.entityId',operator: "in",value: ri!entityId),a!queryFilter(field: 'recordType

 Hi all,Has anyone run into this with record list export where record has a column type Translation String field?I have a record type where one of the columns (e.g. `Label`) is of type Translation String. When I use the standard Download option on the record list, the export fails with:Query has failed: Cannot invoke "java.util.Map.get(Object)" because "translationProperties" is nullA few important details:- The record list itself renders fine in the UI; only the Excel/CSV download fails.- The error happens even if:- The Translation String column is not selected as a visible column on the record list, or  - The current filter returns only rows that don’t have Translation String values.- I see the same behavior on another record type that also has a Translation String column.It looks like the export logic is trying to read some internal `translationProperties` metadata for the Translation String field and finds it `null`, but I’m not sure what in the configuration would cause that.Has a

All the process variables currently contain null values:pv!currentCase pv!redeemedLoans pv!amortizationWe are using the following expression to exclude null values:reject( a!isNullOrEmpty(_), { pv!currentCase, pv!redeemedLoans, pv!amortization } )However, when all process variables are null, the expression returns an empty list, which causes the error. The input “Records” must not be null or empty.Is there an alternative way to configure the XOR gateway that it skips the write operation when all values are null?, since i dont want to increase number of node by adding xor gate ?

Hello, I'm trying to write a record event with specific data of the changed record, using record event as an audit table, but I'm not sure how to get the data of a specific record when I'm writing multiple record in the same node, there is any clue on it?

Hi,I’m working on a proof of concept for handling concurrent user updates using optimistic locking with a @Version field.This works well when using CDTs/Data Store Entities because Appian/Hibernate can use the version column to detect when a record has been updated by another transaction and prevent one user from overwriting another user’s changes.For synced Record Types, however, it does not appear that there is currently equivalent support for a version field that can participate in optimistic locking during record writes.Are there any plans to support @Version-style optimistic locking for synced Record Types / Write Records?The use case is to prevent lost updates when multiple users open and edit the same record at the same time, while still allowing us to detect conflicts and provide a merge/resolution experience to the user.If this is not currently planned, is there a recommended Appian-native pattern for implementing optimistic concurrency with synced Record Types?Thanks!

Hello everyone,  I have a table with several fields 'year_field' and 'month_field' forming the table's primmary key. It's mandatory that the fields remain as primary key. When I do that, Appian doesn't allow you create record or cdt associated with the data store. I have come up with a solution, but it might not be the optimal one. I will show it to you just in case either you have something to add or different way to make it better. The idea is to create a procedure to write, update and delete data in the table. Instead of using 'Write Record' node, the procedure would be triggered based on the operation you want to perform. For reading purposes, I have thought to create a 'Materialize View' where the view includes the primary key. That is my solution. If you have a smarter way to do this, please let me know. King regards and thanks

 We have a form called in the record action , a new row is added when the form is submitted in a grid. Based on the grid values we are displaying a card for above the grid for achievement rate. But card is refreshing with the current achievement rate only after manually refreshing page or switching tabs,its not updating immediately after this record action is completed.Where as for editing grid values and saving we are using a save button which is updating immediately after the process completion.How to solve this issue?  

I am using a!eventHistoryListField() with comments enabled and the mentionableUsers parameter so that users can @mention colleagues in record event history. However, in our production environment end users do not have access to Tempo at all. They only use Sites.The problem:When a user is mentioned in the event history comments, Appian automatically sends the built‑in @mention notification email. The link in that system email takes them to Tempo → Record → Summary, not Site → Record → Summary. Since they have no Tempo access, clicking the link results in an error. We would like to keep the @mention search/picker behavior, but: Either replace the built‑in @mention emails, or Use the mentions only as a way to identify users and then send our own custom email with a Site-based record URL. ( with no automated emails)  

I am currently facing an issue where record actions configured at the interface level are completely inaccessible.Security settings: Checked and verified,all configurations appear correct.This behaviour started occurring within last few days.Has anyone else faced this recently?(For workaround  we have set “securityOnDemand “ parameter to false to all recordActionFields which are using at interface level) 

Hi everyone,We're using the native Export to Excel feature on a records-powered read-only grid, and we've noticed that export time increases significantly as the number of columns grows, even when the row count stays roughly the same. I wanted to check with the community on a few points: Does the native export re-execute the underlying query? When a user clicks "Export to Excel," does Appian re-run the same query that populates the grid (re-fetching data from the data source), or does it reuse the dataset that's already loaded/paginated in the grid? Where can we check logs for this? Is there a specific log (e.g., tomcat-stdout, application server log, or a dedicated export log) where we can see the actual query being run during export, along with timing/duration details? We'd like to confirm whether the slowdown is on the query side (DB) or on the Excel-generation/serialization side (building the workbook itself). Thanks in advance!

Today all my query entity started giving below error suddenly even I tried with batch size 2 Not sure if this is an issue in DB or in appain. connected system is getting verified  Expression evaluation error at function a!queryEntity_22r2 [line 21]: An error occurred while retrieving the data. Details: Unexpected error executing query (type: [MRCPFCompanyDT63035], query: [queryentity expression], order by: [[Sort[defaultOrder asc]]], filters:[(active = TypedValue[it=26,v=1])])

Hi, I need help understanding why record sync is not occurring when using the "Write to Datastore" smart service in one environment, while the latest data appears in the records in another environment. In the environment where sync is not happening, a manual sync is required to view the latest data. Can someone help me understand the cause of this issue?

Hi All,I need to show some details when i place cursor on the sample id which is a clickable link .Is it possible to show tooltip for a record action Field function or are there any other alternates.a!gridColumn(label:”Sample Id”,value:a!recordActionField(display:”LABEL”,style:”LINKS”,openActionsIn:”NEW_TAB”,actions:{a!recordActionItem(action:recordType.task,identifier:index(fv!row,sampleId,null)})

Hello Appian Support Team,I am using the Appian Community Edition environment for learning.When I try to create a new Record Type using the “From Scratch” option, I receive the following error:“The data source cannot be reached or its configuration is invalid. Please contact your system administrator.”Could you please check whether there is an issue with the database/data source configuration in my environment?I would appreciate your help in resolving this issue so I can continue with the learning exercises.Thank you.

The related actions are not working, when I click on it is showing the loading icon, but they are not working as expected and not displaying the list of related actions. 

Hi,Could you explain me why the mix of relationShips and fields in “index/value”, does not work in a a!update() function  please ?Do I have any other choice but to call 2 consecutive a!update()?/* Works fine: */a!update( data: local!data, index: { recordType!Project.fields.createdBy, recordType!Project.fields.createdOn } value: { "my.user", now() })/* Works too: */a!update( data: local!data, index: recordType!Project.relationships.Document, value: local!docs)/* Does not work: */a!update( data: local!data, index: { recordType!Project.relationships.Document, recordType!Project.fields.createdOn } value: { local!docs, now() })Regards

Hello All, I’m currently using a View-based synchronized Record Type in Appian to display data on the front end(Dash Board). While the underlying data in the source has been updated and the latest information is visible in the database view, the changes are not being reflected in the Record Type as expected. Could anyone share suggestions or best practices for ensuring that modified data is refreshed and synchronized correctly within the Appian Record Type? Any guidance on how to retrieve the latest updates efficiently would be greatly appreciated. Thank you in advance for your support and insights.

How to create a record type from scratch?

Hello The instance has got paused at the write node the record value is not going as empty there was no error msg also after running the instance again i have got this error msg ERROR:Work item cancelled (Data Inputs) 

I am new in Appian application development. Can any one please help me to know how can I get and use the Import CSV to Database smart service? Should I use any Plug-ins? If yes where from I can get it? I searched for it but did not get it.

Hi All,I have a record type with one of the filters on this record is a Date Range filter on a due date field.Several departments want to save a view where the filter always defaults to "Today". but when Users save the filter with today's date selected, it saves the literal date (12-08-2026) rather than a relative reference. So the saved filter becomes stale the next day instead of always reflecting the current date. ( Default in the user filters doesn't make much sense because users will combine this due date filters with several other filters).Is there a way to save a Date Range filter so it stores a relative value rather than a fixed date, so it stays dynamic across days?As a option B, I'm considering adding a new filter with a dropdown that offers options like "Until today" / "Future Cases," which I could implement with relative date logic. But that would mean maintaining two separate filters for the same column (the original Date Range plus this new dropdown), which isn't my prefe

I know Appian internally tracks the Last Sync Time for synced record types and displays it in the Monitor View → Record Sync Status and Sync History screens. However, I haven't found any documented or supported way to access this information programmatically within an application. Specifically, is there an expression function, query API, record metadata API, or other supported mechanism that exposes a record type's last successful sync timestamp for use in interfaces, process models, or expression rules?If not, what is the recommended approach for applications that need to display or validate the most recent sync time?
