Refeodinventory batch error

Hi All,

I'm using RMS 14.1

During the run of  RMS schedule of batches, I start to have the below error:

"refeodinventory~20151220191146~EXEC_SQL_T~ERROR: ORA-03114: not connected to ORACLE REF_SNAP Failed"

and I'm finding ITEM_LOC_SOH_EOD table without Index and Primary Key.

I'm creating the index and primary key, and running the batch, this time without error.

This is a good practice?

Do you have other solutions?

Thank you for your answers,

Adriana
