Hi, I have to pass a value from an SAP screen exit to a third-party tool -- Albany verify, which is in VB 6.0 -- to validate the value passed from SAP. I also need a return value back to SAP on the validation performed in the third party tool. Does anyone have any tips?

Thanks. We'll let you know when a new response is added.

You can use ALE with a Custom iDoc holding only that one field. This will be sent to the external party from SAP using a connection based upon TCP / IP.

Good luck!

    I would define the interface components in data dictionary and then (as a placeholder for the 3rd party software in SAP) an empty function module incorporating the interface references. Up to 4.6C SAP function builder can create the visual basic coding which must be reviewed and corrected, but it saves a lot of time. Lastly you must define a logical destination like "3rdparty" in SAP (sm59) to itentify the 3rd party software. In the SAP user exit you may call the placeholder function module, extenting the call with "destination 3rdpart".

    Two ideas: 1. Use WS_DOWNLOAD() (or whatever?) to export the data to the workstation from the user-exit. Write a VB executable that reads and validates the data - also call it from the exit with WS_EXECUTE() just after the download. Reverse the process to import the results. Sounds yucky but it works smoother than it sounds. 2. VB works great with RFC's directly but you need to know how to generate a FRC interface via the SAP DCOM compiler and incorporate it into a VB prg. Then you have a little smoother integration.
