Hi Dave,
Looks like I am close to my solution.
I have tried /SAPSLL/API_6850_SYNCH.
In the header structure IS_API6850_HDR I have filled only the PRODUCT_GUID, PRODUCT_ID, CHANGEDBY, DATAB (mm/dd/yyyy) and PRBUM_ISO. Is that enough?
Then I filled attribute table with PRODUCT_GUID, PRODUCT_ID and ATTR01B
I unchecked IV_UPDATE_TASK. IV_COMMIT is checked.
CV_LOG_HANDLE is blank.
But still it is not updating the required attribute.
I don;t get any error either.
Thanks
Gopal
