ECM Neophite

Hello everyone I am pretty new to the AS400 world and even newer to ECM. I am 
trying to use ECM along with Extol and I have been to training for Extol but I 
am having the worst time trying to get a class scheduled through SSA GT. I have 
mapped data from Extol into my BPCS tables but I am stuck on how to get data 
into BPCS (Sales Orders). I have tried to read all the help information that 
was available but to no avail.

My question is whether or not anyone can lead me in the right direction as far 
as "getting started' with ECM. This has been very irritating and it is not very 
productive for me.

Anything would help while I try to get a class set up through SSA.

I am currently trading through Harbinger's Trustedlink for Windows and I am 
trying to integrate EDI to the 400 where the transactions that I would like to 
process are:

850's, 810's, 997's and 856's.

TIA

Antonio S
