The days of wading through thousands of function modules are over. Whether you need more information about a particular function module or just want to see what's out there, you've come to the right place. This book is packed with only the most-used function modules in the SAP system. Make your coding easier and view logic in a whole new way! 1. Most-Used Function Modules Find only what you need. After exhaustive research of where-used lists and Google hits, thousands of function modules have been narrowed down to hundreds of the most important and commonly used. 2. Topic Groupings Don't know what you're looking for? No problem. Function modules are grouped into different parts, based on usage and topics like authorizations, IDocs, and BAPIs. 3. User-Friendly Layout Information at a glance: Each function module contains a description, example, and list of parameters and their description for optimal use. 4. Extensive Index Looking for something specific? Search the index not only by function module name, but also by key word, functionality, related SAP program, and more. 5. Transaction Codes Make connections. Search for common transaction codes in the index to link your functional knowledge with insider programming know-how.

In this part of the book, we refer to system as the SAP ERP or SAP NetWeaver system. This part deals with more of the Basis-related operations that can include calling a new transaction, calling SAP NetWeaver from legacy systems such as Java or Visual Basic, or from an FTP server or a remote location.
Function modules (FMs) are important when working with the system because it helps get the system information—such as the IP address, user authorizations, user login and logoff—by calling a transaction in another window without interrupting the execution of the current window. In this part, we’ve included the important FMs that are commonly used and interact in some way with SAP systems and Basis operations.
1 ABAP4_CALL_TRANSACTION
This FM is used to call a transaction code in the same task or a separate task (i.e., in the same session or window). If you want to call the transaction in a new task, you need to call the FM with Starting New Task. This is an RFC-enabled FM, so it can be called from non-SAP systems as well. Authorization rules of the calling transaction apply.
Example: You have an ALV output with the list of materials. Clicking on the material, you want to open the details of that material (i.e., opening Transaction MM03) in a separate window.
Import
TCODE
Specifies the transaction code you want to call. This is a mandatory parameter. Type: SY-TCODE.

Type: SY-FTYPE.
UPDATE_VAL
Defines how the update will occur. It can have the following values.
A: Asynchronous update.
S: Synchronous update.
L: Local updates.
Type: SY-FTYPE.
Export
SUBRC
This is a SY-SUBRC check. It returns the value as 0 if the FM is executed successfully. Type: SY-SUBRC.
Table
USING_TAB
Contains the BDC data for the transaction; that is, if some BDC recording is sent to call the transaction. Type: BDCDATA.
SPAGPA_TAB
