&FUNCTIONALITY&
This function module was generated from
object <LS><(>&<)>1</> and method <LS><(>&<)>2</>
, for BAPI calls using ALE.
The interface of the module was defined as a standard API in ALE. The
data is provided by the ALE layer.
The function module is executed in the inbound system by the ALE layer.
It converts the data from the IDoc into BAPI parameters and calls the
BAPI in the inbound system. For more information about this BAPI, see
>>>>DOCULINK<(><<)><(><<)><(><<)><(><<)>.
When this module is executed, a new IDoc status is written. This status
indicates either that the BAPI was called successfully in this system
(status 53) or that errors occurred (status 51).
BAPI return parameters specify how the ALE layer writes the IDoc status.
If errors occur, the ALE layer is responsible. How the BAPI return
parameters work:

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

If the BAPI return parameter is an EXPORTING parameter, one single IDoc
status record is written. If the message has type A or E, the IDoc is
given status 51 (application document not posted). Otherwise (for
message types W, I, or S), the IDoc is given status 53 (application
document posted).
If the return parameter is a tables parameter, multiple IDoc status
records can be written. Message types determine the IDoc status. If a
message has type A or E in the table, status 51 is written for the IDoc
(application document not posted) for all entries except those with the
type S (entries with types A, E, W, or I). For messages with type 'S',
no IDoc status appears. If a message in the table has type 'A' or 'E',
status '53' (application document posted) is written for 'W', 'I' or
'S'. The status records are written to the database in the same sequence
as the messages in the return parameter.
If the return parameter is empty, the BAPI call was successful. In this
case, an IDoc status record with status 53 (application document posted)
is written by the ALE layer.
If errors occur, the application must ensure that the data is
consistent, for example by rolling back unwanted changes.
You can use the ALE error handling functions (create a work item) to
process any errors.

• What is the cause and solution for SAP error message B1566 - BDBG: Dummy for Documentation of Inbound Function Module ?

  The SAP error message B1566, which states "BDBG: Dummy for Documentation of Inbound Function Module," typically occurs in the context of Business Application Programming Interfaces (BAPIs) or when working with inbound function modules in SAP. This message is not an error in the traditional sense but rather a placeholder or a documentation message indicating that the function module is not fully implemented or lacks the necessary documentation.
  Cause:
  
  Incomplete Implementation: The function module may not have been fully developed or implemented, leading to the dummy message.
  Documentation Placeholder: The message serves as a reminder that the function module is intended for documentation purposes and may not perform any actual processing.
  Development Environment: This message can appear in a development environment where the function module is still under construction.
  
  Solution:
  
  Check Function Module: Review the function module in transaction SE37 or SE80 to ensure it is fully implemented. If it is a dummy function, you may need to implement the required logic.
  Consult Documentation: If you are using a standard SAP function module, check the SAP documentation or notes for any updates or changes related to that function.
  Contact Development Team: If you are not the developer, reach out to your development team to clarify the status of the function module and whether it is intended to be used in production.
  Testing: If you are testing an integration or interface, ensure that you are using the correct function module and that it is intended for your use case.
  
  Related Information:
  
  Transaction Codes: Use SE37 to view and edit function modules, and SE80 for a broader view of the development objects.
  SAP Notes: Check SAP Notes for any known issues or updates related to the specific function module you are working with.
  Debugging: If you are debugging and encounter this message, it may be helpful to set breakpoints in the function module to understand its flow and identify any missing logic.
