Hi Guys,

I wanted to know the various conversion techniques for Sales BOM i.e techniques like LSMW and BAPI's. what i want to know is the various possible techniques to transfer data from non-SAP Systems to SAP-Systems.

Thanks and regards,

Frank

Hi,

Data can be transfered from legacy system to SAP through:

1.LSMW

2.Through Program.

In program upload the excel file stored as tab delimited. then run BDC or upload through Update statement.

Hi Sonali,

Thanks for the Answer. Bt wht i wanted to know is tht is this a general conversion technique?? if it is , i need a technique which is specific to Sales BOM.

Thanks and Regards,

hi frank,

which technique should be used purely depends upon the requirement and data and many constraints but not surely upon the type ex: sales order etc.

so, depending upon ur requirement u need to decide that

Hi Hymavathi,

Thanks for your reply but could you please tell me how do i identify which of these i.e BAPI , LSMW or BDC is the best method of Conversion.

Thanks and regards,

Frank.

first check whether a BAPI is available for that or not or consult ur functional consultant.

if BAPI is there then BAPI would be the best. else go for BDC.

again in BDC it would be better if u include both the types call transaction and session method.

this can be done by including a single include in ur report

include bdcrecx1.

Hi,

For migrating data from non-sap to sap there are many methods.

Actually atpresent we are in conversion project.If the data is in large numbers(lakhs of records) , then to upload easily u can follow LSMW with Batch Input / Direct Input Method. If standards are not available, then go for BAPI's. If BAPI's are not available, then BDC.

But when u use BAPI, data is accurate.

Finally u keep BDC.
