Hi George,
If you are getting a single (valid) account, you should be correctly connected. I have a few suggestions yoou may want to try:
1. Verify in your company wizard if you selected GP Financials or Analytical Accounting. Do not use AA unless you actually have AA data.
2. See if the user you log in as makes any difference. MR enforces account level security so verify the user you are logging in as is not restricted. Try logging in as 'sa' if you can.
3. Validate the GL account you gets back is actually a valid account. Often we see people's natural account set incorrectly in GP under Setup | Company | Account Format.
4. There have been just a few updates to MR, but verify you have installed them. You should be installing Management Reporter with the SP1 release, and then updating to FP1 and installing the updated provider in that release. Your version should be 2.0.1664.19 from Help | About.
Thanks
Ryan
