Approach for WS to SAP synchronous?

[Former Member]

Hi All,

My scenario is WS to SAP synchronous and working on PI 7.1.

here webservice request will come to PI and need to update data into sap database tables. and response should be sent back to webservice.

For this scenario which option is good.

WS(SOAP adapter)<-->Proxy.

WS(SOAP adapter)-->RFC lookup in mapping for updating data into database table and getting response and mapping this response to webservice.

ie WS>RFC Lookup>WS

please sugggest which one will hold good in this scenario.

Thanks

Hi,

The 1st approach should be fine ! RFC lookups are not supposed to be used to update data (no transaction isolation and rollback), only for data retrieval ...

Furthermore, SAP often delivers BAPI to perform data update/create and they offer more flexibility and security than direct updates ... You can also wrap them into a proxy
