Master data upload via LSMW using IDoc method

Dear all,
I know this has been a topic of many discussions but I would like to ask you is to share your thoughts and possibly experience with the following scenario:
Interface between non-SAP system and SAP system has to be built whereby master data gets created in the non-SAP system and has to be uploaded into SAP. This is a process that needs to be performed on a constant basis and hence my question: is there a way that the MD upload takes place in the background via LSMW with IDoc? Or any other way, for instance, with a flat file, etc.?
Thank you very much for your input!
Regards,
Miro

Miro - It depends upon many factors
1. Number of source systems
2. Volumn of recorsds ( Data to be loaded)
3. Transformation needed or not needed from S to D ( source to destination), We may consider it as
    business rules/mapping
Based on above you may segrigate the objects related to data, eventually you can shoose approach of loading in SAP,
As if straigt forward load for some 20k-30K records ( Just a file load on regular basis), one to one mapping then go for LSMW, if some complex transformation logic needed then go SAP data services implementation. best part here is if you multiple sources that can be handeled here.
Accordingly you can proceed ...
Hope it helps.
Best !

    hi
    thanx for ur answer
    requesting every body in the forum to help me how to create lsmw using idoc method.

    Hi Balaji,
    LSMW using IDOC is similar to using flat file method. Here you are getting data from IDOC container and mapping data with Idoc segments insted of flatfile column.
    Hope this is what you are looking for. If helpful then don’t forget to reward me for that

  • LSMW using IDoc Method *Error :No partner exists with the name '', type ''*

    Hi All,
    I am a newbie. I am trying LSMW using IDoc Method.
    I got an error when i executed Start IDoc Generation step: No partner exists with the name '', type ''
    Could anyone tell what wrong I might have done,
    Thank you,
    Shiv Ram

    Hi,
    You have to setup your IDoc configuration in LSMW:
    1) Enter the menu \Settings\IDoc Inbound Processing
    2) Create a FILE port by clicking "Maintain Ports"
    3) Create a logical system (LS) partner number by clicking "Maintain Partner Numbers"
    4) Be sure your partner profile that you create is "Active" by clicking "Classification"
    5) In the end click "Activate IDoc Inbound Processing" bottom.
    Run your LSMW again. This time it shoud run wothout any problem.
    Hope it helps.

  • Working on LSMW using IDoc method for processing Open Sales Orders

    We are currently in middle of creation of a new instance of production for a different Business SBU. We are looking to utilise the LSMW tool using IDocs for uploading / transferring the open orders to the new box. If some one has worked on LSMW using IDocs, please get in touch and if you could share any documents on the process of utilising the LSMW tool using Idocs for any kind of conversions, it would be great. The following is a sample case.
    1. Each order will have multiple segments with different qualifiers under various segments.
    2. Multiple line items would be available under each order.
    Issues we are currently looking to solve :
    1. How do you manage to loop through the qualifiers during processing for the same segment.
    2. How do you prepare the tool to recognise the multiple line items of the same order.
    3. What kind of strategy needs to be used to create the input data file(s). Like, splitting the header and detail level information ?
    Note  : The volume of data we are looking at is somewhere around 40-60 thousand orders worldwide.
    Thanks in Advance.

  • Data Migration-LSMW using IDoc Method

    Hi Friends,
    I have contract relevant information in the form of a excel spreadsheet/tab delimited flat file.
    This transactional data has information such as Header Data, Item Data and Sub Item data (BOM explosion).
    I need to migrate this data from the flat file to the CRM application using the IDoc Method of LSMW.
    /When I used the Batch Input Recording method, the item data was not captured during recording./
    Kindly send me relevant information to [email protected]
    Thanks in Anticipation
    rgards,

    Hello Sven,
    thanks for your comment. Unfortunatelly those both transactions do not exitst because I work on SAP CRM 7.0 instead of SAP ECC. I also looked for similar transactions in the table but didn't find anything.
