# Triggering SAP code from Looply

You can instruct your Looply workflow to make an HTTP request to SAP by using the *HTTP Request (SAP)* step. While you can make a request to any SAP endpoint, the ABAP Looply Add-On provides two endpoints with hook points to call your own custom code and these will be discussed here.

## POST Data to SAP

### Set-up on Looply

Configure your step as follows:

#### SAP Profile

Here you may Use the dropdown to select any of your pre-configured SAP Profiles that you have created and integrated with Looply. 

Often however you may want the workflow to send the request to the system in your landscape that it was triggered from, instead of maintaining a different workflow for your development, quality and production systems. You can do this by toggling the *Bind profile dynamically* switch and binding the *System ID* and *Client ID* fields with the respective fields in your payload. When Looply workflows are triggered by the /LOOPLY/CORE=>TRIGGER\_WF method, these fields are added to the payload automatically.

#### Service Path

Enter the following path: **/sap/opu/odata/looply/service\_srv/**

Note: If you have included a / at the end of the *Host URL* field in your SAP integration do not include it at the start of the service path as the values of the two fields are concatenated when the request is made.

#### Entity Name

Enter the following value: **DataInSe**t

#### Request Method

Select **POST**

#### Body

You may add the following fields to the request body:

<figure><img src="/files/Br2V5Lt2UCYHu7X2RSdR" alt=""><figcaption></figcaption></figure>

With the exception of field scenario\_id, the rest of the fields are optional and can be omitted. In the above screenshot, the first four fields are bound to fields in the payload (see section [Triggering a Looply Workflow](/integrations/sap-integration/triggering-or-resuming-a-looply-workflow-from-sap.md#triggering-a-looply-workflow) for more details) and will be used to determine the Z-function to be called once the request reaches the back-end. *data* contains additional data we want to send to the back-end and may include fields from the payload, information about a button the end-user clicked on, data entered into fields on the card (you can find more information on how to pass data from the card to the workflow [here](https://academy.looply.ai/integrations/sap-integration/pages/wgJsiyF3JzmHtJC4ZSj8#action.submit) ) etc. In this example we have used a function step which outputs a json string containing all these fields.

### Configuration in your SAP system

In your SAP system, create a new function module by copying sample function */LOOPLY/SAMPLE\_POST.* The function has the following signature:

<table><thead><tr><th width="175">Parameter Name</th><th width="78">Type<select><option value="7PeeNLqDkkwr" label="Import" color="blue"></option><option value="pPvjjLIx59Z2" label="Export" color="blue"></option></select></th><th width="116">ABAP Type</th><th>Description</th></tr></thead><tbody><tr><td>IM_DATA</td><td><span data-option="7PeeNLqDkkwr">Import</span></td><td>STRING</td><td>Data passed in from Looply workflow. (corresponds to request body field <em>data</em> above)</td></tr><tr><td>EX_SUBRC</td><td><span data-option="pPvjjLIx59Z2">Export</span></td><td>SYSUBRC</td><td>Subrc code passed back to the workflow</td></tr><tr><td>EX_MESS</td><td><span data-option="pPvjjLIx59Z2">Export</span></td><td>BAPIRET2</td><td>Message to be logged in the SAP log and passed back to the workflow</td></tr><tr><td>EX_DATA</td><td><span data-option="pPvjjLIx59Z2">Export</span></td><td>STRING</td><td>Data passed back to Looply</td></tr></tbody></table>

TIP:  To convert an incoming json string to an internal table or structure you can use method /ui2/cl\_json=>serialize. To convert an internal table or structure to a json string to be passed back to Looply you can use method /ui2/cl\_json=>deserialize.

Next, make a configuration entry via the following IMG transaction: \
SPRO->General Application Functions->Looply->Process Determination\
Insert the values passed into the request body for fields *Scenario, Scenario ID, Version, Step* and the name of your newly created function module in field *Function.* You may leave fields *Workflow ID* and the non-key *Version* field blan&#x6B;*.* When the request reaches the back-end, the configuration table will be read based on the *Scenario, Scenario ID, Version and Step fields* and your function module will be called dynamically.&#x20;

## Download file from SAP

In certain scenarios, you may wish to include a button or a link to download a file/attachment from your sap system in a Microsoft Teams card. You can achieve this in the following way:

### Example - Adaptive Card

Insert a Container to your card. (You can use any container type that that has a "*Selection action*" property like a *ColumnSet* or *TableCells* if you have multiple attachments)

<figure><img src="/files/vFnPfrtDrtcce9M011WW" alt=""><figcaption></figcaption></figure>

If a gateway service endpoint which fetches the file already exists on your sap system you may use a url to that service. (Stelo users for example can include a url to Stelo service /STELO/APP\_SERVER\_SRV/AttContentSet to retrieve attachments in their payload. For example:\
[https://\<host>/sap/opu/odata/stelo/app\_server\_srv/AttContentSet('\<attachment cms document>')/$value](https://demo05.arch.co.uk:44300/sap/opu/odata/STELO/APP_SERVER_SRV/AttContentSet\('ACL-TID2-E-00-1000004307-0002-01'\)/$value) ) &#x20;

In other scenarios, an endpoint that fetches the file you want to download might not exist. In such cases you can use a url to the endpoint provided by the Looply ABAP add-on: [https://\<host>/sap/opu/odata/looply/service\_srv/AttSet(scenario='\<scenario>',scenario\_id='\<scenario\_id>',version='\<version>',step='\<step>',data='\<data used to get file>')/$value](https://fiori-dev.sunderland.gov.uk/sap/opu/odata/LOOPLY/SERVICE_SRV/AttSet\(scenario='WI',scenario_id='WS93000012',version='2',step='002',data='10400921__0045000241'\)/$value)

Using a url with the above format will allow you to call your own Z-function to return a file.  You can create such a Z-function by copying  sample function */LOOPLY/SAMPLE\_GET\_FILE.* The function has the following signature:

<table><thead><tr><th width="175">Parameter Name</th><th width="78">Type<select><option value="7PeeNLqDkkwr" label="Import" color="blue"></option><option value="pPvjjLIx59Z2" label="Export" color="blue"></option></select></th><th width="116">ABAP Type</th><th>Description</th></tr></thead><tbody><tr><td>IM_DATA</td><td><span data-option="7PeeNLqDkkwr">Import</span></td><td>STRING</td><td>String from 'data' url parameter</td></tr><tr><td>EX_SUBRC</td><td><span data-option="pPvjjLIx59Z2">Export</span></td><td>SYSUBRC</td><td>Subrc code passed back to the workflow</td></tr><tr><td>EX_MESS</td><td><span data-option="pPvjjLIx59Z2">Export</span></td><td>BAPIRET2</td><td>Message to be logged in the SAP log and passed back to the workflow</td></tr><tr><td>EX_XDATA</td><td><span data-option="pPvjjLIx59Z2">Export</span></td><td>XSTRING</td><td>File data in XSTRING format</td></tr><tr><td>EX_MIME_TYPE</td><td><span data-option="pPvjjLIx59Z2">Export</span></td><td>STRING</td><td>File Mimetype</td></tr><tr><td>EX_FILENAME</td><td><span data-option="pPvjjLIx59Z2">Export</span></td><td>STRING</td><td>Filename</td></tr></tbody></table>

Next, make a configuration entry via the following IMG transaction: \
SPRO->General Application Functions->Looply->Process Determination\
Insert the values that match the url parameters for fields *Scenario, Scenario ID, Version, Step* and the name of your newly created function module in field *Function.* You may leave fields *Workflow ID* and the non-key *Version* field blan&#x6B;*.* When the request reaches the back-end, the configuration table will be read based on the *Scenario, Scenario ID, Version and Step fields* and your function module will be called dynamically.&#x20;
