[CAP] Fiori Elements – Add section with PDFViewer
I have a CAP Service that provides a PDF file that I needed to display in a Fiori Elements frontend using the sap.m.PDFViewer. The viewer should be placed in a section on the object page after navigating from the ListReport main page.
My CAP Service has the following annotations to provide the PDF.
entity pdfFiles : cuid, managed {
content : LargeBinary @stream @Core.MediaType: mediaType @Core.ContentDisposition.Filename: fileName @Core.ContentDisposition.Type: 'inline';
mediaType : String @Core.IsMediaType: true;
fileName : String @mandatory;
}
Add a custom section to your view following this example: https://sapui5.hana.ondemand.com/test-resources/sap/fe/core/fpmExplorer/index.html#/customElements/customSectionContent
Two steps are necessary.
1. Add a new section via the manifest. The template path should match your app namespace.
"ObjectPage": {
"type": "Component",
"id": "ObjectPage",
"name": "sap.fe.templates.ObjectPage",
"viewLevel": 1,
"options": {
"settings": {
"editableHeaderContent": false,
"entitySet": "pdfFiles",
"content": {
"body": {
"sections" : {
"myCustomSection": {
"template": "sap.fe.core.fpmExplorer.customSectionContent.CustomSection",
"title": "{i18n>pdfSection}",
"position": {
"placement": "After",
"anchor": "StandardSection"
}
}
}
}
}
}
}
}
2. Add the section content by defining a new fragment in the file CustomSection.fragment.xml
<core:FragmentDefinition xmlns:core="sap.ui.core" xmlns="sap.m" xmlns:l="sap.ui.layout" xmlns:macro="sap.fe.macros">
<ScrollContainer
height="100%"
width="100%"
horizontal="true"
vertical="true">
<FlexBox direction="Column" renderType="Div" class="sapUiSmallMargin">
<PDFViewer source="{content}" title="{fileName}" height="1200px">
<layoutData>
<FlexItemData growFactor="1" />
</layoutData>
</PDFViewer>
</FlexBox>
</ScrollContainer>
</core:FragmentDefinition>
On the ObjectPage you will now have a new section containing the PDFViewer.

[SAP] Login to SAP for Me and other SAP Websites via Certificate
Go to https://me.sap.com/app/sappassport, request your certificate and install it in your Browser. Working with the BTP is much more convenient now, as you don’t have to enter your credentials all the time.
[CAP] CQL Expand Composition / Deep read
In the documentation they always use a star in string literals like this o => o.`*` to select all fields, but when running this it always failed. However, after some tests I found that this format works with brackets o => o.('*')
https://cap.cloud.sap/docs/guides/providing-services/#–-deep-read
entity myEntity: cuid, managed {
field1 : String;
comp : Composition of one myComposition;
}
aspect myComposition: cuid, managed {
myCompField: String;
}
const result = await SELECT.from(myEntity)
.columns(e => {
e('*')
e.comp(c => c.myCompField) //expand composition, but only select 'myCompField'
})
Update 14.09.2023: is now fixed (#)
[CAP] CQL Deep Update
A Composition of one can be updated via the Parent Entity, like we would do it, when dealing with an Association to one.
entity myEntity: cuid, managed {
field1 : String;
comp : Composition of one myComposition;
}
aspect myComposition: cuid, managed {
myCompField: String;
}
const { myEntity } = srv.entities
const EntityComposition = srv.entities['myEntity.myComposition'] // composition
srv.after('CREATE', EntityComposition , async (comp, req) => {
await UPDATE(myEntity, comp.ID)
.set({
comp : [{ myCompField: 'test' }]
})
})
A Composition of many must be updated via the actual Composition Entity.
entity myEntity: cuid, managed {
field1 : String;
comp : Composition to many myComposition;
}
aspect myComposition: cuid, managed {
myCompField: String;
}
const EntityComposition = srv.entities['myEntity.myComposition'] // composition
srv.after('CREATE', EntityComposition , async (comp, req) => {
await UPDATE(EntityComposition, { up__ID: comp.up__ID, ID: comp.ID }).set({ myCompField: 'test' })
})
[CAP] UploadSet http test file
How to create an uploadSet in combination with a CAP backend: https://blogs.sap.com/2021/08/18/my-journey-towards-using-ui5-uploadset-with-cap-backend/
You can test the uploadSet CAP backend part using these http calls:
### Create file
# @name file
POST http://localhost:4004/v2/admin/Files
Authorization: Basic admin:
Content-Type: application/json
{
"mediaType": "image/png",
"fileName": "picture.png",
"size": 1000
}
### Fill Variable from Response
@ID = {{file.response.body.$.d.ID}}
### Upload Binary PNG content
PUT http://localhost:4004/v2/admin/Files({{ID}})/content
Authorization: Basic admin:
Content-Type: image/png
< ./picture.png
### Get uploaded png
GET http://localhost:4004/v2/admin/Files({{ID}})/content
Authorization: Basic admin:
The picture.png file must be in the same folder as the http test file.
[CAP] Dynamically set destination in package.json for an external connection
"cds": {
"requires": {
"sfsf": {
"kind": "odata-v2",
"credentials": {
"destination": "<set during runtime>",
"path": "/odata/v2",
"requestTimeout": 18000000
}
}
}
},
/*
* Handover query to some external SF OData Service to fecth the requested data
*/
srv.on("READ", Whatever, async req => {
const sf_api_def = cds.env.requires['sfsf'] //defined in package.json
sf_api_def.credentials.destination = "myDestinationName" //set your Destination name, could come from a customizing table
const sfsfSrv = await cds.connect.to(sf_api_def)
return await sfsfSrv.run(req.query)
})
[CAP] Providing destinations locally using .env
The provided example
destinations="[{\"name\": \"TESTINATION\", \"url\": \"http://url.hana.ondemand.com\", \"username\": \"DUMMY_USER\", \"password\": \"EXAMPLE_PASSWORD\"}]"
didn’t work for me. I had to change it to the following format:
destinations=[{"name": "TESTINATION", "url": "http://url.hana.ondemand.com", "username": "DUMMY_USER", "password": "EXAMPLE_PASSWORD"}]
You can check the current value using:
process.env.destinations
