Want to extract data from a SAP BW system via webMmethods

Dear All,

I’ve got an requirement to do feasibility study to extract data from SAP data source Extractor via webMethods.

As per my knowledge, SAP adapter will use RFC method to connect to SAP.
Is there any alternatives to trigger SAP data source Extractor like below?

2LIS_01_S001
2LIS_01_S005
2LIS_01_S264
2LIS_08TRFKP
2LIS_08TRFKZ
FI-GL-IO
0FI_GL_1
0FI_GL_2
0FI_GL_4
0FI_GL_6
0FI_GL_7
0FI_TX_4

Please assist me, if SAP Adapter can perform perform this execution ?

Any Webserice communication can happen with SAP BW and webmethods,Because i came to know that SAP bW can only push data not able to Pull data and it doesn’t allow you pull data by External systems.

There is no such wS communication mechanism b/w them. You ask them do they use BAPI for communication with other systems.

Thanks,
