Callback is not working on remote but working locally in SAP CRM
The issue lies in the class you are using for making a method call. This class is basically making RFC callback with the help of SAP GUI. So, when you are using the function builder, it works well because it has an SAP GUI connection present. But when you are using an external system, the GUI is missing and it doesn't work. Understanding the Problem When working with SAP CRM, callbacks rely on the SAP GUI framework for proper execution. In a local environment, the SAP GUI provides the necessary interface layer for RFC (Remote Function Call) ...
Read MoreBAPI to upload documents to SAP system is throwing an exception
When using a BAPI to upload documents to an SAP system, you may encounter exceptions indicating that the function module is trying to access GUI-related functions. As mentioned in the exception message, this occurs because the function module attempts to access GUI-related functionality, which doesn't support BAPIs. This suggests the issue stems from either a custom RFC module or a bug in SAP coding, and you should open a support ticket with SAP. Understanding the Root Cause The primary issue arises from improper use of GUI services in non-GUI operations. When developing BAPI functions, you shouldn't use GUI ...
Read MoreUsing SAP Tables from C# application - RFC_READ_TABLE
The RFC_READ_TABLE is a widely used Remote Function Call (RFC) that provides generic access to SAP tables from external applications like C#. This function module allows developers to read data from any SAP table without creating custom ABAP code. Key Considerations for RFC_READ_TABLE Many users use RFC_READ_TABLE as the primary API for generic table access from C# applications. Joins are not directly supported in RFC_READ_TABLE − However, this limitation can be overcome by implementing joins in your C# application logic. If you encounter complex requirements, you can request your ABAP developer ...
Read MoreRequest Timeout while using Odata call to a gateway in SAPUI5 application
When encountering request timeout issues while making OData calls to a gateway in SAPUI5 applications, the problem often lies in the server-side timeout configurations rather than the client-side code. This typically occurs when ICM (Internet Communication Manager) and Web Dispatcher timeout settings are insufficient for your application's requirements. Understanding SAP Timeout Parameters In SAP systems, ICM and Web Dispatcher control different types of timeouts through specific parameters − Connection timeout: icm/conn_timeout − Controls the timeout for opening a connection Request timeout: icm/traffic_control − Controls the timeout for receiving ...
Read MoreRFC returns exception while using SAP RFC_READ_TABLE to output data to software
When working with SAP RFC_READ_TABLE function module, you may encounter RFC exceptions that prevent data extraction to external software. You can check if there are any short dumps in the SAP system using T-Code: ST22. When there are short dumps, it leaves the ABAP Processor in an invalid state. This results in a failed call with an unspecified error message. Checking Short Dumps in SAP To diagnose RFC exceptions with RFC_READ_TABLE, follow these steps − Step 1: Access the SAP system and navigate to transaction code ST22 (ABAP Runtime Error Analysis). Step 2: Review ...
Read MoreRetrieve list of linked documents in SAP
When working with SAP systems, retrieving linked documents is a common requirement for various business processes. SAP provides several RFC (Remote Function Call) modules specifically designed to fetch document lists and their associations with business objects. Available RFC Functions for Document Retrieval There are multiple RFC functions available to fetch the list of documents in SAP. You can try any permutation and combination to identify which suits your specific requirement − BAPI_MATERIAL_GETLIST − Retrieves material documents and their associated links ...
Read MoreExecuting an inner join over RFC on database tables in SAP system
You can execute inner joins over RFC on database tables in SAP systems using several approaches. You can do this by creating your own function module that can perform selection as per the requirement. Methods to Perform Inner Joins Method 1: Custom Function Module Create a custom function module in SE80 or SE37 that performs the inner join logic and returns the required dataset. This approach gives you full control over the join operations and performance optimization. FUNCTION Z_CUSTOM_INNER_JOIN. SELECT a.field1, b.field2 FROM table1 AS a ...
Read MoreExisting RFC to load table data, and to get list of tables and list of BAPI's in SAP
I am not sure that there exists a BAPI to see list of all BAPI's in SAP system. You can use the Function module RFC_FUNCTION_SEARCH to search for function modules starting with BAPI*. Getting List of BAPIs You can call Function Module BAPI_MONITOR_GETLIST to get list of all available BAPI's. This function module provides comprehensive information about Business Application Programming Interfaces available in your SAP system − CALL FUNCTION 'BAPI_MONITOR_GETLIST' EXPORTING OBJECTTYPE = p_ojtpe SHOW_RELEASE = ...
Read MoreUsing table parameter in SAP RFC Function module
When working with RFC enabled function modules in SAP, you should use a structure as line type for the table parameter. This approach ensures proper data handling and type safety when transferring tabular data between systems. Creating the Dictionary Structure First, you should declare a dictionary structure Z_MY_PARTS_DATA with a single field DESCRIPTION TYPE CGPL_TEXT2. This structure defines the layout of each row in your table parameter. TYPES: BEGIN OF z_my_parts_data, description TYPE cgpl_text2, ...
Read MoreUser rights required to make a call to SAP RFC Function Module RFC_SYSTEM_INFO from JAVA application
When you use Java connector you need basic authorization to read metadata of Function Module. S_RFC is an authorization object for the RFC call.This object contains the following fieldsRFC_TYPE Type of the RFC object you want to protect. You can pass the value 'FUGR'- function group) or 'FUNC'- function module.RFC_NAME Name of RFC to be protected. This file contains a value of the function group or of function modules.CTVT ActivityThis field may take the value 16.In case you want a user to be able to call function modules in-group 'ABCD' remotely, following user authorization is required ...
