Q17. Do I Need An Extensive Knowledge Of Abap To Use The Lsm Workbench?

No. The LSM workbench presents the principle conversion strategies at the rush of a button. For complex conversions, character ABAP coding can be delivered.

Q18. State The Difference Between Lsmw And Bdc?

LSMW is essentially designed for practical specialists who do no longer do much coding but want to explore the capability at the same time as BDC is designed for a technical representative.

LSMW gives different technique for migrating information: Direct enter, BAPI, I-Doc, Batch enter recording while BDC essentially uses recording.

LSMW mapping is executed by means of SAP even as in BDC we should do it explicitly.

LSMW is basically for popular SAP utility whilst BDC essentially for customized utility.

Coding can be finished flexibly in BDC while as compared to LSMW.

Q19. What Are The Main Functions Of Lsmw?

The three primary functions of the LSMW are:

Reading the legacy facts from one or several files (e.G. Spreadsheet tables, sequential files).

Converting records from its original (legacy gadget) format to the target (SAP) layout

Importing the statistics using standard interfaces (Batch Input, Direct Input, BAPI, IDoc) into the database of the R/three software.

Transaction Code to begin the LSM Workbench is LSMW.

Q20. What Kind Of Data Can Be Migrated Using The Lsmw? Is It Certain That The Imported Data Will Be Consistent?

Wide variety of Master Data (e.G. G/L bills, purchaser grasp, seller master, material master, payments of fabric) and Transaction Data (e.G. Monetary documents, income orders) can be migrated the use of LSMW.

Yes, the imported information may be constant because the information is loaded thru wellknown interfaces of the packages to be able to include all tests that are run for on-line transactions. 

Q21. What Is Data Migration & What Is The Significance Of Data Migration. State The Most Important Data Migration Tools Available In Sap?

Data Migration stands for facts transfer among two like or alike structures. During SAP R/three implementation the facts wishes to be moved from legacy gadget to the SAP gadget. Sometimes periodic information switch between R/3 and different machine (interfacing) is also required. Both of the above shape a part of records migration.

Significance of statistics migration are:

Data migration comes in the long run of R/three implementation.

To start with Data Migration first configuration have to be completely completed

Data migration is ready 20% to 40% of the total implementation fees.

The equipment for facts migration are:-

BDC (Batch Data Communication)

LSMW (Legacy System Migration Workbench)

Q22. Can Lsmw Be Used For Handling Multiple Recordings?

Generally Multiple Recordings are achieved for transactions which has multiple get right of entry to sequences like VK11, TK11, etc. Batch Input Method is capable of handling multiple recording and Batch Input recording is one of the import strategies available in LSMW. So yes, LSMW may be used for managing multiple recordings.

Q23. What Are The Advantages Of Lsmw?

It's a code unfastened device (however if required coding can be done) - Therefore it allows functional humans to add statistics from legacy to SAP machine.

Since it is an uploading device supplied via SAP, it has a dependent way of running. You can have to complete each step earlier than beginning the following step.

Since it's miles incorporated in R/3 it's far impartial of man or woman platform. The whole challenge may be downloaded and uploaded in any environment in contrast to BDC which needs to be developed in improvement server and then transported to Production Server.

It can be favored while there's a need to upload large quantity of information.

It is desired best if there may be a requirement for one time switch of information.

Q24. Which Data Can Be Migrated Using The Lsm Workbench?

By way of trendy transfer applications: a extensive range of master facts (e.G. G/L debts, purchaser grasp, vendor master, material grasp, payments of material) and transaction statistics (e.G. Financial files, sales orders)

By manner of recording of transactions: further data gadgets (if the transaction can be run in batch enter mode)

Q25. Can I Be Certain That Conversions Are Carried Out Identically Across The Applications?

Yes. The LSM Workbench works on the precept of crucial (reusable) policies. This method ensures that, as an instance, the fabric wide variety is converted in the equal manner wherever the reusable rule is used for conversion.

Q26. What Is Lsmw All About?

LSMW is a device provided via SAP for you to add huge amount of data from legacy document to R/three machine. The Legacy System Migration Workbench (LSMW) is a tool to transfer records from legacy systems (Non SAP System) into an R/3 System (SAP System).

LSMW supports a step-with the aid of-step process; if one step is accomplished and stored then subsequent step robotically follows.

Apart from introduction of venture/ subproject/ object and recording, there are 14 fundamental steps included in LSMW.

Through LSMW you can create Master data, create transactional information, alter present master information and so on. This device is very beneficial whilst some mass adjustments are to be completed and no wellknown SAP transactions are to be had for that.

There are few fashionable gadgets available in LSMW e.G. Cloth master, supplier master, patron grasp, shopping data record, purchase requisitions, buy orders etc. Using these wellknown objects you will do mass statistics add and mass transactions.

Apart from this LSMW presents some other functionality of recording the transaction after which wearing that out normally with big statistics. Examples are mass deletion of buy requisitions, mass deletion of planned orders and many others.

Q27. Can I Migrate From R/3 To R/3 Via Lsmw?

Yes, however:

Export needs to be programmed

Source systems should be described

Fields of the supply systems may be loaded from the dictionary

Mapping needs to be finished manually è a whole lot of fields!! Automatic fieldmapping is probably used Import of massive facts amounts can take a number of time (most of the time information amount is better than for Migration from legacy structures) History facts can not be build up maximum of the time
