PO Awaiting Approval After Change

Question

Hi Gurus,
We are on SRM 7.0ehp1 and ECC 6.0.
I'm new to SRM business.
In our case, requirement is created in backend and after approval it is transferred to SRM. RFx is created via sourcing application. After that, PO is created both in SRM system and backend systems using the RFx responses. There is no approval in SRM system.
Our problem is, when we make any change (except adding an internal note from notes and attachment part in header tab ) in PO, its status turns into 'Awaiting Approval' and backend document  is not changed according to this. And after. that i get 'No work item ID provided' error messages when i try to edit the PO.
Thank you very much in advance.
