ABAP coding in LSMW

Former Member — Tue, 02 Jan 2007 13:00:56 GMT

Hi All,

A)Is it possible to write ABAP coding in LSMW, if yes where can we do this. and

B)During the First Step of LSMW we come across 1. Standard/Batch Direct Input

2.Batch input recording

3.Business Object Method (BAPI)

4.IDOC(intermediate document)

which one to use and when to use?

C) what are the advantages/disadvantages of LSMW compared to other data transfer methods like BDC.

please let me know the answers for above.

useful answers will be rewarded for the same.

Regards,

Yellappa.

Hi,

A) Yes. you can write routines,conversion in LSMW in 6th step.

B)Depends on the client requirement (Business requirement)

C) It is flexible rather than BDc, No programming knowlege required, So Functional consultants can also setup LSMW.

hi u can do it during

A) the field mapping step, for every field we will have EDITOR and there we can write the code

B) batch input recording, this makes things easier, depensing on the level of comfort level people use others

C) if u want to use complex coding then we shud gor for BDC's and in case of urgent attention if u want to avoid the workflow process then also we need to use LSMW over BDC's and directly export

We generally use LSMW in case of updation of large databases

Hi Yellappa,

A) You can write ABAP code in LSMW. Go to following step "Maintain Field Mapping and Conversion Rules". Just write click on a filed in change mode & choose option "INSERT RULE". It will give you one popup screen. In this popup screen choose option "ABAP Code". Here you can write your code.

Hi Bhupal,

you are saying that we can write write subroutines and conversion routines. can we do the processing in that as we do in BDC.

also Can you please explain the difference between the four methods like BAPI, IDOC etc and in performance wise which one would be better

Regards,

Yellappa.

Hi Ashvender,

Is the ABAP code in LSMW only for input validation or we can do our own coding kinding of thing.

Hi Rahul,

How do we handle the errors in LSMW. Can we schedule it in background.

Regards,

Yellappa.

we can schedule LSMW background job in SM35, and if at all any errors occured we can get them in LOG created

errors occured in the log show the reason for error

yes we can write coding in LSMW .

U can capture the error records & download it in .txt or .xls or .csv files by writing coding in End of processing block in Maintain field mapping & conversion rules step.

U can declare datas as in se38 also in global data definition & declaration block.

U can validate ur input append it in internal table & process it.

to capture error & continue the process we use skip_record.

check it.

for q posed to ashvinder, its used only for validation of the input records and their corresponding processing, i will explain a simple scenario,

1. if u want to transfer data a part of which has already been created in the system. You

want to decide at runtime whether the data is created or changed.

u can write this coding in corresponding field

2. You want to "skip" a record depending on a certain condition, i.e. this record shall not be converted and transferred to the output file.

3. Duplicate a Record

If want complex pricing procedures u cant do that in LSMW, u need to go for BDC's

for ur question about what to use, BAPI or IDOC, check this link
