I think, all of the parameters are obvious, except szPOOptionID.
Open the PO template with the PO Designer and print the definition from there. You will se the IDs for all PO field.
Did you ever complete this program? Did you have to run this on a fat client since the N9090001 business function is client only? I would like to write a similar program to run in Scheduler and update the dates for our month-end jobs automatically, but I don't know if there is any way to update the processing option blob data from a UBE running on the enterprise server.
After making copy of it to run on Client & Server, it throws me this error "COB0000012 - GetProcAddress failed" even though I could see the bsfn exists in DLL.
Has anyone found a way to automatically update the PO values in the UBE version at month's end?
