Don't see 'ACME AUTO' application for hands-on activity of Developers Learning Path

I’m doing Appian Learning Path. I don’t see ACME AUTO application in my community edition for Hands-on Activity of ‘Appian Essentials’ course. How can I access it?

Write to data store using forEach

Vladislav Morozov — Sun, 03 May 2026 16:27:13 GMT

Hello, I'm trying to write an array of data using foreach in a write to multiple data store entities, but it gives me error without specifying what could be wrong: here is the code and the error:

a!forEach(

items: pv!getDocuments,

expression: {

a!entityData(

entity: cons!CM_REF_CLAIM_DECLARATION_DOC,

data: 'type!{urn:com:appian:types:CM}cm_ref_claim_declaration_doc'(

idClaimDeclDoc: index(fv!item, "documentId", null),

idDoc: index(fv!item, "documentId", null),

idClaimDecl: pv!id_claim_declaration,

createdBy: index(fv!item, "documentLoadUser", null),

createdOn: index(fv!item, "documentLoadDateTime", null)

)

if(

or(

a!isNotNullOrEmpty(fv!item.letterTemplate),

a!isNotNullOrEmpty(fv!item.letterCreationDate)

a!entityData(

entity: cons!CM_DSE_LETTER,

data: 'type!{urn:com:appian:types:CM}cm_letter'(

idClaimDecl: pv!id_claim_declaration,

idClaim: pv!claimDeclaration.idClaim,

idRisk: pv!claimDeclaration.idRisk,

sentDate: index(fv!item, "letterSentDate", null),

idDoc: index(fv!item, "documentId", null),

createdBy: index(fv!item, "letterCreationUser", null),

createdOn: index(fv!item, "letterCreationDate", null),

receivedDate: index(fv!item, "documentReceptionDate", null)

)

{}

a!entityData(

entity: cons!CM_DSE_DOCUMENT,

data: 'type!{urn:com:appian:types:CM}cm_document'(

idDoc: index(fv!item, "documentId", null),

docName: index(fv!item, "docName", null),

docDescription: index(fv!item, "documentDescription", null),

receiptDate: index(fv!item, "documentReceptionDate", null),

uploadedDate: index(fv!item, "documentLoadDateTime", null),

uploadOwner: index(fv!item, "documentLoadUser", null),

idDocMacroCategory: index(fv!item, "documentIdMacroCategory", null),

idDocMicroCategory: index(fv!item, "documentIdMicroCategory", null),

status: index(fv!item, "letterStatus", null),

sendLetterDate: index(fv!item, "letterSentDate", null),

createdBy: index(fv!item, "documentLoadUser", null),

createdOn: index(fv!item, "documentLoadDateTime", null),

enrichDate: now()

)

}

)

Is the "forEach" a problem? How should I write it then?

RE: Write to data store using forEach

manojtumulu — Fri, 08 May 2026 04:34:03 GMT

Before write to DB, add a temporary rule input:

=a!localVariables(
local!data: <your expression>,
local!data
)

Inspect:

Any null
Any duplicates (primary key value)
Any unexpected {}

and make sure flatten the structure bcz write to Multiple Data Store Entities expects

[
entity1,
entity2,
entity3,
...
]

Use Insert->Code to enter code lines for better readability in Community

RE: Write to data store using forEach

Shubham Aware — Thu, 07 May 2026 05:43:44 GMT

Write to Multiple Data Store Entities smart service expects a flat list of a!entityData() - but a!forEach returns an array of arrays (one array per iteration), which breaks the smart service input.

use a!flatten():

a!flatten(
a!forEach(
items: pv!getDocuments,
expression: { ... }
)
)

and keep {} for the false branch, not null.

Urgent: Community Edition Access Needed for Certification Re-attempt (India Region | No Response for around 2 Weeks)

sagniknandi — Thu, 23 Apr 2026 15:10:10 GMT

Hello everyone,

I am currently preparing for the Appian Associate Developer Certification and urgently need access to a Community Edition (CE) environment.

My registered work email is: sagnik@alumnux.com
I am attempting to access the platform from the India region.

I had previously been provisioned a CE workspace under this email, but it was later deactivated due to inactivity. I have since raised multiple requests for a new environment and also emailed the Community Edition team over two weeks ago, but have not received any response.

I would also like to mention that I attempted the certification exam on 21-Apr-2026 but was unable to clear it, primarily due to lack of sufficient hands-on practice in the Appian environment.

I am now preparing for a re-attempt and require CE access to complete the exercises in the learning path and strengthen my practical understanding.

If any moderators or Appian team members could please assist in re-provisioning access or guiding me on the correct next steps, it would be extremely helpful.

Thank you in advance for your support.

Regards,
Sagnik Nandi

Cannot insert records to use "Write Records Smart Service" in Process Model

shanguiy394945 — Sun, 19 Apr 2026 15:59:58 GMT

Hi everyone,

As the title suggests, I am having trouble inserting data using the "Write Records" in smart service.

I have configured the node according to the official documentation, but I keep encountering an error that prevents the data from being inserted.

I would appreciate it if anyone could help me identify the cause of this issue.

RE: Cannot insert records to use "Write Records Smart Service" in Process Model

shanguiy394945 — Mon, 20 Apr 2026 07:06:01 GMT

Thank you so much! I ensured the Process Variables were populated before reaching the Write Records node as you suggested. That fixed the issue!

RE: Cannot insert records to use "Write Records Smart Service" in Process Model

Shubham Aware — Mon, 20 Apr 2026 05:44:56 GMT

Your pv! LAWloanApplication has No Value. Write Records needs a populated record type instance, not an empty PV.
Assign values to the PV before the Write Records node using a Script Task.

if you are using a grid you could try something like this:

a!localVariables(
/* Example data to load into the TravelReimbursement record type.
Replace the field names with your actual record fields. */
local!dataToLoad: a!forEach(
{
a!map(
employeeId: 1001,

tripStartDate: today() - 5,
tripEndDate: today() - 3,
destination: "Chicago",
amount: 420.50,
currency: "USD",
status: "Submitted"
)
},
cast(
/* Use your travel reimbursement record type here */
recordType!TravelReimbursement,
fv!item

),

/* Track whether we've already written the data */
local!submitted: false,

/* Refresh the grid data when local!submitted changes */

Unable to Store data entered in interface to the data store

swaroopk07 — Thu, 09 Apr 2026 09:47:27 GMT

I am creating the workflow for the travel imbursement.

The data entered in the interface is not being stored in the Database.

I am using latest version (26.3) of community edition India region.
Can I get solution for this or alternate way for this.

RE: Don't see 'ACME AUTO' application for hands-on activity of Developers Learning Path

Harsha Sharma — Tue, 14 Apr 2026 13:20:42 GMT

okay then you should be able to deploy the app to your workspace using the Steps Shubham has mentioned already.
Community Edition home-> App Catalogue -> Acme Automobile Applications -> Deploy App to workspace.

I opened the ‘Appian Designer’ from Home Screen under the ‘BUILD YOUR FIRST APP’. I can see the ACME AUTO now.

In the hands-on activity, instructions are to open the navigation from top right menu

Screen shots from hands-on Activity (to open navigation from top right menu) and from where I opened the 'Appian Designer' are below

Thank you everyone!

Once you log in to the Appian Community Edition designer, click the waffle icon and go to Community Edition Home. On the right side, you will see the App Catalog option, and under that, you can find the Acme Automobile applications.

RE: unable to access database/create a datamodel in appian community

Shubham Aware — Fri, 10 Apr 2026 12:03:02 GMT

The page's interface contains a Record List grid (readonly) with an error. Since the grid has an issue, the interface fails to render.
Fix the grid error in the Record Type first, then the preview will load.
