Introduction:
The aim of this document is to provide a strategy and detailed procedure for recovering ALE communications from a system failure. The various kinds of failures that can occur will be described and the procedures to recover from these failures will be described.

Transport Guide Tips for SAP Objects
Here are tips for different objects:
LSMW: There are 2 ways for transporting LSMW data from a system to another.
Export/import this method gives you the opportunity to select the subprojects or objects you want to transfer. LSMW -> Extras -> Export project
Transport request with this method, you can transport a LSMW project in full (you can not select the objects you want). With this method, the project will be transported as any other SAP object in a transport order. LSMW -> Extras -> Create change request
Basics of IDoc
An IDoc (intermediate document) is a standard data structure for electronic data interchange (EDI). IDocs are used for the data interchange between SAP systems as well as between an SAP system and an external system. IDocs serve as the vehicle for data transfer in SAP’s Application Link Enabling (ALE) system. The contents, structure, sender, receiver, and current status of the IDoc are defined in the IDoc header.Data acquisition from an SAP source system is a very common scenario in SAP BW. This process involves extracting the data using either standard business content-provided extractors or custom-built extractors.
Failure of data to load usually leads to loss of productive time in re-triggering the extraction.
ABAP/4 Optimization
ABAP/4 programs can take a very long time to execute, and can make other processes have to wait before executing. Here are some tips to speed up your programs and reduce the load your programs put on the system:
- Use the GET RUN TIME command to help evaluate performance. It’s hard to know whether that optimization technique REALLY helps unless you test it out. Using this tool can help you know what is effective, under what kinds of conditions. The GET RUN TIME has problems under multiple CPUs, so you should use it to test small pieces of your program, rather than the whole program.
Checklist for LSMW
Pre-Check LSMW: To-Do-List Before Using the Tool
The LSM Workbench is a tool that supports the transfer of data from non-SAP systems to R/3. Basic functionality of the LSM Workbench:
1. Import old data from spreadsheet tables or sequential files.
2. Convert the data from source format into target format.
3. Import the data into R/3.
