SQL stored procedure for Objecttype: payment engine FORM??

Hello,

This is my first time visit here. Hope someone can help me out.

Situation

user 1 is only allowed to create a payment proposal via the payment wizard. So can only save the proposal and not Execute!

User 2 (chief) can opens the proposal ( saved payment wizard proposal user 1 created) and clicks on execute.

Basically how do I achieve that user 1 can only create a proposal and can not choose execute.

What I tried and failed

standard SBO authorizations. I blocked user 1 to create outgoing payments. Although I blocked user 1 for this with the payment wizard when user 1 selects EXECUTE the user can create outgoing payments. A bug if you ask me....

SQL stored procedure: SP_notification.... create stored procedure for @object_Type 46 ( this is document type for Outgoing payments) that if user1 Add one an error will appear. This solution is not enough because it does not block anything.

question

Does anyone has a suggestion in order to solve this issue? or does someone know, what the @Object_type is for the payment wizard form Step 6 of 9 ( where you make te option what you want to do Execute or save).

thanks in advance
