The XCO library offers classes such as XCO_CP_XLSX and methods for reading and writing XLSX content. You can find more information here. The following example demonstrates a selection of methods.
Expand the following collapsible sections for further information and example code.
🟢 Click to expand for more information and example code
The following example demonstrates a selection of methods and includes the following steps:
- Importing existing XLSX content into your SAP BTP ABAP Environment system (not related to the XCO library; just to have content to work with in the self-contained example below)
- This is a simplified, nonsemantic, and explorative RAP example (not delving into RAP as such; just using various ABAP repository objects related to RAP) solely for importing XLSX content to work with in the example.
- The import is done using an automatically created SAP Fiori Elements app preview, which provides a simple UI for uploading local XLSX content.
- The repository objects are automatically created in ADT when walking through a wizard. Refer to the prerequisite steps for details.
- Reading XLSX content into an internal table using XCO
- Writing XLSX content using XCO based on internal table content
- A demo class explores a selection of XCO classes and methods.
- Exporting the adapted XLSX content (not related to the XCO library; just to visualize newly created XLSX content using XCO)
[!NOTE] - Note this repository's disclaimer and the disclaimer in the documentation about XCO for security considerations when importing and processing external content. - IDE actions represent a simple way of file import. Find more information in section Excursion: Exploring Demo Display Class Using IDE Actions.
Prerequisite Steps for the XLSX Content Import into the SAP BTP ABAP Environment
The XLSX XCO module works with XLSX content in the form of an xstring. The following example assumes that you have XLSX content available as xstring. To try out the example, you can proceed as follows:
- In your ABAP Cloud project in ADT, create a database table in the desired target package. This example uses the name
ztdemo_abap_xlsx. - Give it a description, such as Demo table, and assign it to a transport.
- Set up the example database table as follows:
@EndUserText.label : 'Demo table'
@AbapCatalog.enhancement.category : #NOT_EXTENSIBLE
@AbapCatalog.tableCategory : #TRANSPARENT
@AbapCatalog.deliveryClass : #A
@AbapCatalog.dataMaintenance : #RESTRICTED
define table ztdemo_abap_xlsx {
key client : abap.clnt not null;
key id : sysuuid_x16 not null;
file_content : abap.rawstring(0);
file_name : abap.char(128);
file_mimetype : abap.char(128);
@AbapCatalog.anonymizedWhenDelivered : true
local_created_by : abp_creation_user;
local_created_at : abp_creation_tstmpl;
@AbapCatalog.anonymizedWhenDelivered : true
local_last_changed_by : abp_locinst_lastchange_user;
local_last_changed_at : abp_locinst_lastchange_tstmpl;
last_changed_at : abp_lastchange_tstmpl;
}
- Activate the database table.
- In the Project Explorer view on the left, locate your created database table and right-click on it. Choose Generate ABAP Repository Objects... from the top section of the context menu.
- This opens the Generate ABAP Repository Objects dialog box.
- Select OData UI Service. Find information on the right about the RAP-specific repository objects to be created. These objects include CDS entities, BDEFs, ABPs, service definition and binding, among others.
- Choose Next.
- Select the package and choose Next.
- The next screen in the dialog box lets you specify additional details for RAP repository objects, such as alias names. However, you can also leave it as is and choose Next.
- The following screen displays a list of artifacts set to be created. Choose Next.
- Then, select the transport request and choose Finish.
- The creation of the repository objects may take some time. Once completed, the service binding will appear. Keep it open, but refrain from making any adjustments at this point.
- Proceed to access the generated CDS entity. Note that two CDS entities are created. Access the one without the with projection on specification (the example entity name is
ZR_TDEMO_ABAP_XLSX). The specification appears as follows.
...
define root view entity ZR_TDEMO_ABAP_XLSX
as select from ZTDEMO_ABAP_XLSX
...
- Adapt the CDS entity as follows. It is essential that the
@Semantics annotations are specified and the provided names match.
@AccessControl.authorizationCheck: #NOT_REQUIRED
@Metadata.allowExtensions: true
@EndUserText.label: 'Demo CDS Entity'
define root view entity ZR_TDEMO_ABAP_XLSX
as select from ztdemo_abap_xlsx
{
key id as Id,
@Semantics.largeObject: { mimeType: 'FileMimetype',
fileName: 'FileName',
contentDispositionPreference: #ATTACHMENT }
file_content as FileContent,
file_name as FileName,
@Semantics.mimeType: true
file_mimetype as FileMimetype,
@Semantics.user.createdBy: true
@UI.hidden
local_created_by as LocalCreatedBy,
@Semantics.systemDateTime.createdAt: true
@UI.hidden
local_created_at as LocalCreatedAt,
@Semantics.user.localInstanceLastChangedBy: true
@UI.hidden
local_last_changed_by as LocalLastChangedBy,
@Semantics.systemDateTime.localInstanceLastChangedAt: true
@UI.hidden
local_last_changed_at as LocalLastChangedAt,
@Semantics.systemDateTime.lastChangedAt: true
@UI.hidden
last_changed_at as LastChangedAt
}
- Activate the CDS entity.
- Return to the service binding located in your package under Business Services -> Service Bindings (e.g.
ZUI_TDEMO_ABAP_XLSX_O4). - Choose the Publish button for the Local Service Endpoint. The publishing may take some time.
- After publishing, locate the Service Version Details section on the right. Under Entity Set and Association, right-click the newly created entity set and select Open Fiori Elements App Preview.
- This action opens the SAP Fiori Elements app in a new browser window.
- Within the app, choose the Create button.
- You should see a Browse button in the FileContent field.
- Choose this button and select a local XLSX file. Note: You can use the example XLSX content provided below. Only with this content does the example class work properly. For your own explorations, adapt the class code accordingly.
- After uploading the file, choose Create at the bottom to save the entry.
- Refer to the comments in the example class below. You can either exit the app now, leaving one entry in the database with the XLSX content, or use the UUID value of the created entry in the
WHERE clause of the SELECT statement at the beginning of the main method implementation below.
[!NOTE] - If there are issues with the UI (e.g. you cannot upload), try out UI V2. - Create a new service definition, e.g. right-click the Service Definition folder and choose New Service Definition. - Provide a name (e.g. ZUI_TDEMO_ABAP_XLSX_O2) and description. Choose Next. - The code should look as follows: ``abap @EndUserText.label: 'Service Definition' define service ZUI_TDEMO_ABAP_XLSX_O2 provider contracts odata_v2_ui { expose ZC_TDEMO_ABAP_XLSX; } ` - Activate it and create a new service binding, e.g. by right-clicking the service definition and choosing <em>New Service Binding</em>. - Create the binding (e.g. with the same name as the service definition ZUI_TDEMO_ABAP_XLSX_O2`), and select OData V2 - UI as Binding Type. - Activate and publish the local service endpoint. - Access the preview app as described above.
📝 Example XLSX content
- Copy and paste the following data into your demo XLSX file. The example only uses simple character-like values. Note the information in the documentation about value transformation when processing the XLSX content. - Your XLSX creation program may have a feature, such as text to column, that can help you divide the text into separate columns. In this case, the first four columns are filled. - The delimiter is a comma, indicating that there are four columns to be filled with the demo data. - Name the first worksheet (where you insert the demo data) Sheet1. `` AA,American Airlines,USD,http://www.aa.com AC,Air Canada,CAD,http://www.aircanada.ca AF,Air France,EUR,http://www.airfrance.fr BA,British Airways,GBP,http://www.british-airways.com CO,Continental Airlines,USD,http://www.continental.com DL,Delta Airlines,USD,http://www.delta-air.com LH,Lufthansa,EUR,http://www.lufthansa.com JL,Japan Airlines,JPY,http://www.jal.co.jp NW,Northwest Airlines,USD,http://www.nwa.com QF,Qantas Airways,AUD,http://www.qantas.com.au SA,South African Air.,ZAR,http://www.saa.co.za SQ,Singapore Airlines,SGD,http://www.singaporeair.com SR,Swiss,CHF,http://www.swiss.com UA,United Airlines,USD,http://www.ual.com ``
Exploring the XCO XLSX Module
Assuming you have the XLSX content created and uploaded above on your system, you can explore the following example using the XCO classes/methods. To try it out, create a demo class named zcl_demo_abap. If it already exists, reuse it. Otherwise, create a new class with a different name. Paste the code into it. If you choose a different class name, update the class name in the code snippet accordingly. After activating it, choose F9 in ADT to run the class. The example is designed to show output in the console.
[!NOTE] - Refer to the comments in the code for information. - If you have used different names than those in this example, make sure to replace those names in the code. - If your artifacts have a different setup, names, or XLSX content, the example class will not function properly. You willl need to modify the class code to match your specific requirements.
