How to avoid error "[2048]: column store error: search table error: [47] message not found"?

Dear experts, 

I do experience an error thats most likely caused by the hana system running out of memory.

Could not execute 'create local temporary column table #[...] as (select [...], ...'

SAP DBTech JDBC: [2048]: column store error: search table error:  [47] message not found

The error occurs while executing a full join statement on two rather big tables.

• Am I right with my initial guesswork and is the error really caused by hana running out of memory?
• Any Ideas how i can avoid this error without reducing the data (e.g. by adding "where"- constraints) would be highly appreciated!

Many thanks in advance for your responses,

Tobias Müller
