WorkFlows stuck in error NR 889 - No Free Interval Found

Former Member

Hi Experts,

Approx 800 odd Workflows tries to send IDOCs (data flows) at the same time and approx 50 of these workflows get stuck on that step with error message NR 889 - No Free intervals found.

We restart these workflows later through transaction SWI2_DIAG so that all the IDOCs are sent in time, however a permanent solution is required for this issue so that workflow do not stuck in this error.

Please suggest.

Regards,

Nidhi

Hi,

1. Either increase the number range to match with the number of workflows triggering

2. Trigger the workflow in batches and not all together.

Thanks.

By increasing the number range, do you mean I should increase the main memory buffering number (Default is 1000) for object EDIDOC (Number range for IDOCs) or should I change the main memory buffering to Parallel buffering.

Hi,

Is the number range problem with the IDocs themselves, or with the documents they are creating?

If it is with the documents, you need to configure more number ranges - how many depends on the number of parallel processes that are posting these documents.

For example, if you have 3 documents posting concurrently, then you need to have 3 number ranges for these types of documents.

cheers
