SAP Execute

In this article

Overview

You can use this Snap to execute the SAP Business API (BAPI) with the given input data. The BAPI input schema and output schema must correctly map data into the SAP BAPI.

SAP BAPIs for Integration

BAPI technology in SAP is based on import and export parameters that determine the parameters that must be provided (import) and parameters to be returned (export). You can test the BAPI's in the SAP client through transaction code SE37.

Import parameters contain data to be transferred from SnapLogic to the BAPI. Specific values must be provided as import parameters for the BAPI to execute and return the desired data.
Export parameters contain data to be transferred from the BAPI back to SnapLogic. The data returned can be of the following types:

  • S = success message

  • E = error message 

  • W = warning message 

  • I = information message 

  • A = termination message (abort)

The list of BAPI's in a particular SAP client varies depending on the level of customization. However, an exhaustive set is delivered as standardized BAPI's which provide basic functions and can be used to read and write or change data for most SAP Business Objects. 

BAPIs for Reading Data

The following BAPIs provide you with read-only access to data in the associated business object:

  • GetList: Select a range of object key values, for example, company codes and material numbers.

  • GetDetail: Retrieve details of an instance (one specific occurrence) of a business object and returns this data to the calling program. This information is reported back to the calling program.

  • GetStatus: Query the status of an SAP Business Object, for example, the processing status of a sales order. This BAPI is used only for displaying the status of an object and does not retrieve full details like the BAPI GetDetail.

  • ExistenceCheck: Checks whether an entry exists for an SAP Business Object, for example, whether the customer master has been created. 

BAPIs for Creating or Changing Data

The following BAPIs can create, change or delete instances of a business object:

  • Create or CreateFromData: Creates an instance of an SAP Business Object, for example, a purchase order.

  • Change: Changes an existing instance of a SAP Business Object, for example, a purchase order.

  • Delete and Undelete: Deletes an instance of an SAP Business Object from the database, for example, a purchase order. The BAPI Undelete removes a deletion flag. 

  • Add<sub-object> and Remove<sub-object>: Adds a sub-object to an existing object instance and the BAPI and Remove<sub-object> removes a sub-object from an object instance.

Snap Type

The SAP Execute Snap is a Write-type Snap.

Prerequisites

  • Set up the user (the SAP BASIS administrator should create the user) to be used in the appropriate SAP clients with a specific set of authorizations. To execute a BAPI as part of your application program, you must have the appropriate authorizations set up in respective master records. The documentation provided with the BAPI contains information about the required authorizations. Any attempts to execute a BAPI that fail as a result of insufficient authorization are reported back to the calling application.

Input

Document

Min: 0
Max: 1

  • Mapper

Document that conforms to the input view schema of the Snap. The document attributes are matched to the SAP BAPI metadata, and the matching attributes are provided to the BAPI program at execution, and any non-matching attributes are ignored.
The attributes can be tabular and structured or scalar. The Snap makes an API call for each document. If there is no input document, the Snap calls the BAPI with no input data.

Only some BAPIs may be able to process without input. Refer to your BAPI documentation for the BAPIs that correctly processes with no input data.

Output

Document

Min: 1
Max: 1

  • JSON Splitter

  • Mapper

  • Any document processing Snap

Document which represents the record structure of the retrieved BAPI output definition. The documents are populated using the result data of each BAPI call for each document passed into this Snap. If the Snap has no input document, only one output document result is created. 

Error

Error handling is a generic way to handle errors without losing data or failing the Snap execution. You can handle the errors that the Snap might encounter while running the Pipeline by choosing one of the following options from the When errors occur list under the Views tab. Learn more about Error handling in Pipelines.
The available options are:

  • Stop Pipeline Execution: Stops the current pipeline execution when the Snap encounters an error.

  • Discard Error Data and Continue: Ignores the error, discards that record, and continues with the rest of the records.

  • Route Error Data to Error View: Routes the error data to an error view without stopping the Snap execution.

SAP BAPIs do not enforce standard error messaging, so error views of Snaps that are downstream of the SAP Execute Snap should be set to Discard Error Data and Continue. Else, your Pipeline will fail to run.

BAPI*

Default Value: N/A
Example: BAPI_MONITOR_GETLIST

 

String/Expression/Suggestion

Specify the BAPI on the SAP server to be executed. This is the ABAP name. 

 

Start Stateful Call Sequence

 

Default Value: Deselected

Checkbox

Select this checkbox to create a stateful session for calling one (or more) BAPIs. A Session ID is required if you want to create a stateful call sequence.

Commit after BAPI execute

 

Default Value: Deselected

 

Checkbox

Select this checkbox to end the stateful session and commit when no exception is raised; otherwise, the BAPI controls the commits.

Session ID

 

Default Value: N/A
Example: xyz987

String/Expression

Specify the string to identify a specific session.

All Snaps in a specific stateful call sequence must be in the same session ID, and there should be only call sequence running in a session at a time. If you do not provide any session ID, the Snap runs in its own session.

 

Date conversion format

 

Default Value: yyyyMMdd
Example: yyyyMMdd

 

String/Expression

Specify the format to convert string input values into SAP date/datetime fields in SimpleDateFormat.
If you do not specify any value, then no conversion is done and the SAP client displays an error when an input view string is mapped to SAP date/datetime field.

 

Output date time as Text

Default Value: Deselected

Checkbox

Select to output date and time as a String data type instead of a DateTime object.

 

Error handling


 

 

Use this field set to define the error path and values for handling errors. If any error paths and their error values match a corresponding value in the output document, then the document is routed to the error view (if enabled), or the Snap fails (if the error view is disabled).

If you do not define the error handling, the Snap will not by default fail or route anything to the error view if the RETURN[*].TYPE value is 'E'.

 

Error path


Default Value: $RETURN[*].TYPE
Example: $RETURN[*].TYPE

String/Expression

Specify the error path to which the errors should route.

 

Error value


Default Value: E
Example: R

String/Expression

Specify the value for the error.

 

Max request attempts*

Default Value: 3
Example:5

 

 

Integer

Specify the maximum number of SAP connection attempts to make in case of a failure. When you specify 0, the Snap makes infinite connection attempts. 

 

Request retry interval


Default value: 5
Example: 5

Integer

Specify the time in seconds to wait before retrying the request.


 

Route errors


Default value: Deselected

Checkbox

Select this checkbox to write configuration errors to the error view. If the error is non-recoverable, the errors (especially connection errors such as exception handling) are routed to the error view with relevant information.

 

Reload Function Metadata


Default value: Deselected

Checkbox

Select this checkbox to reload the metadata (latest schema) for the current BAPI function before executing the BAPI function.

 

Round to SAP decimal*

 

 

Default state: Deselected

Checkbox

Select this checkbox to round the decimal value to match the number of decimal places defined in the SAP target field. This prevents a conversion error if the number of decimal places exceeds the value defined in SAP.

If you deselect this checkbox and the Snap tries to write a decimal value that either exceeds the length or the number of decimal places defined in the SAP packed decimal field, a conversion error is displayed.

Snap Execution


Default value: Execute only
Example: Validate & Execute

Dropdown list

 

Examples


The following examples demonstrate how to retrieve data, insert data in SAP using the applicable BAPI, and display an error.

In the first example we will read a list of all sales orders in SAP by Sales Organization and Customer using BAPI_SALESORDER_GETLIST and then split the data by Sales Order # (SD_DOC), format the data to Excel and ultimately write the data to SLDB.

We will start with a JSON Generator Snap which provides Customer and Organization ID which is input for the Mapper Snap where we map the relevant details such as CUSTOMER_NUMBER and SALES_ORGANIZATION to prepare as your input data.

The SAP Execute Snap is configured to use  BAPI_SALESORDER_GETLIST.  I have renamed the Snap "SAP Execute - BAPI" for the purposes of this example. 

 

The results are returned from SAP, which match the input criteria (Sales Organization and Customer).

 

Next, we split the data by Sales Order using a JSON Splitter. The JSON Splitter can use the SALES_ORDERS path to split the incoming document into individual output documents for each sales order and then write the results to an Excel file using Excel Formatter.

 

We create an actual sales order in the second example. We use the following JSON as the input to the BAPI_SALESORDER_CREATEFROMDAT2 BAPI.

[ { "ITM_NUMBER": "1", "ORDER_HEADER_IN": { "SALES_ORG": "3020", "DIVISION": "00", "DISTR_CHAN": "30", "DOC_TYPE": "TA", "PURCH_NO_C": "000004454" }, "PARTN_NUMB": "0000003041", "PARTN_ROLE": "AG" } ]

 

Then we map the input into the schema for the BAPI_SALESORDER_CREATEFROMDAT2 BAPI .

The image below shows the SAP Execute Snap configuration:

The execution returns the RETURN attribute (and others) which shows the status. TYPE: 'S' indicates a success and provides additional messages.

 

 

Errors are identified in a BAPI as type "E" in the RETURN message. If the BAPI is not able to process the data provided in the input, the message returned should indicate  the corrective action required as in the following example from BAPI_SALESORDER_CHANGE. 

 

The following Pipeline demonstrates a sequence of 3 BAPI calls on service notifications using an SAP instance.

Download this Pipeline.

 

In this example Pipeline, a Mapper (Feed Notification Data) is used to prepare the sample attributes for the notification.

The output displays the notification attributes.

We are using three SAP Execute Snaps to call the following BAPI functions in that sequence.

  1. BAPI_SERVNOT_CREATE : To create a service notification using Create Svc Notification Snap.

  2. BAPI_SERVNOT_SAVE : To save a service notification using SAP Execute Snap.

  3. BAPI_TRANSACTION_COMMIT: To execute external commit when using BAPIs using Save Svc Notification Snap.

SAP Execute Snap to call BAPI_SERVNOT_CREATE and create an SAP
service notification.

SAP Execute Snap to call BAPI_SERVNOT_SAVE and save the SAP
service notification.

  • Select the Start Stateful Call Sequence check box to indicate the  
    beginning of the BAPI sequence.

  • Do not select the Commit after BAPI execute check box.

  • Do not select both the checkboxes in this Snap, as this BAPI is
    an intermediate call in the BAPI sequence.

Mapper Snap to extract the notification number from the saved notification.

SAP Execute Snap to call BAPI_TRANSACTION_COMMIT and commit
 transaction (save service notification).

JSON Formatter Snap to format the output after committing
the transaction.

  • Do not select the Start Stateful Call Sequence check box.

  • Select the Commit after BAPI execute check box in this Snap to 
    indicate the end of the BAPI sequence.

 

File Writer Snap to write the formatted output into a file New_BAPI_Seq_PL_Output.JSON
