JCO Error - Refresh has failed HDB 00102

Hi,

I'm trying to acquire some data from SAP ERP infosets using the JCO connector. It's a basic infoset with a join of two tables: VBRK and VBRP.

If I restrict the SQL call with the date field so there are cca. 20k rows, the upload in Lumira takes 20min (I don't know if this is normal performance, however it is really slow).

When I widen the SQL call so it collects cca. 70k rows, the upload in Lumira ends with an error (after nearly 2 hours!). The error is - Refresh has failed (HDB 00102).

Anyone already hit this error?

Thanks,

Borut
