NetSuite - Only one request may be made against a session at a time
0.7 min read
|Review these options if you are receiving the following message in Extensiv Integration Manager for one or more of your scheduled services:

Only one request may be made against a session at a time
Resolution
By default, NetSuite only allows a single connection per user at a time. This error means that multiple Integration Manager services are attempting to access NetSuite at the same time. There are a few options to resolve this:
- Contact NetSuite sales to purchase a concurrent connection license which allows for multiple connections at once.
- Change your schedules within the Integration Manager NetSuite settings. Use a different schedule for Orders, Confirmations, and Inventory. Alternative change from an hourly to a per-minute schedule for a few minutes and then change back. This will cause Integration Manager to choose a new time to run the job which might not conflict with the other jobs.
- Make sure you aren't using the same user for other automation jobs. If you are, change one of the services to use a different user account.
- You can check this in SalesForce under Setup > integration > Web Services Usage Log and Web Services Process Status. Here you can see logs of all connections to help identify simultaneous connection requests.
