SRM 5 to 7 Upgrade Question

Hello,

We are currently going from SRM 5 to SRM 7 upgrade. In SRM 5.0 we were using BBPSC01 (Shop on behalf of) for most of the user. SRM 7.0 we have configured the same using Operational Purchaser role in Portal but how ever we got question regarding the Refresh Button;

In SRM 5 there is refresh button along with Order, Hold & Check how ever in SRM 7.0 the Refresh button is not available. Is it something removed with SRM 7? The current user community at client location are used to Refresh button to keep the document information update and not to face time out per business policy.

Could anyone know about this Refresh button i can make it available through modification or adding Button?

Thank you

Ritesh
