In SAP Netweaver 740, there is new feature in transaction code secstore. That new feature is “Encryption Key for new and Updated records”.
After the installation or upgrade to ABAP SAP Netweaver 740 with or without SAP application, you must maintain Encryption key for new or updated records.
This is described below with step-by step procedure
Enter tx code secstore in your productive client.
As shown in the figure below, you can see red colour in the Encryption key for New and Updated records. By default, Default key is displayed. This should be changed to Secure Storage filesystem for NW 740 and higher.
This is done by using Key Management on tab. Note that do not use Manage wizard.

This is described in the link http://help.sap.com/saphelp_nw70ehp2/helpdata/en/a0/82dd0abbde4696b98a8be133b27f3b/content.htm
only ABAP applications are supported in SSFS. Java does not support SSFS implementataion. Hence this document is only suitable for ABAP applications.
Do not click on “Manage” button. Instead on tab, click on “Key Management” as shown in the figure below.
You will find two files pertaining to SSFS viz : SSFS_<SID>.DAT which contains database user for SAP objects i.e. SAP Schema user like SAPSR3 and its associated password. As of NW 740, OPS$ mechanism is no longer supported. Instead SAP work processes read the content of SSFS_<SID>.DAT – the entry for SAP Schema user id and its password. However there was no data encryption in these two files.
In order to generate data encryption and store the same in two SSFS files, click on Generate as shown in the figure above.
New Data encryption appeared on the screen. U need to save it for future purpose. AFter backup or save using snapshot complete then click on Continue.
next screen appeared asking to fill up the blank box or box that contains question mark symbol “?”.
Once the box filled up, then click continue
Then click continue to Update existing entries (i.e. SSFS two files) to the new key as shown in the figure below.
Once update complete, you can see the Green colour as shown in the figure below.
