@Hans Andersen  Can you try the following?

page/ShopOrderOperations/List?$filter=OrderNo eq $$ORDER_NO] and ReleaseNo eq $$RELEASE_NO] and SequenceNo eq $$SEQUENCE_NO];scope=Assign

Yes, I tried that too.

An internal server error occurred. Contact administrator.

I have tried all kinds of combinations. 
 

Looks like a bug, @Hans Andersen .  Please raise a case.

This is unfortunate. We were planning to use the functionality extensively. Does it mean that we have to wait for UDP11 before this might be fixed?

@Hans Andersen  Instead of the scope parameter, can you make use of configuration context mappings?

@LakmaliRD ,

We would like use the scope in the link, because the user then can have multiple versions of the same page, designed for a specific task. The example below is for the user to self-assign to an operation on a hand-held device. I have remove all elements, except 3:

Operation no, operation description and command to assign.

We can then have a scope for every task. That is not possible with mappings.

Have the same problem

Have you tried:

put scope first and then ‘&’ 

page/ShopOrderOperations/List?scope=Assign&$filter=OrderNo eq $oORDER_NO] and ReleaseNo eq $oRELEASE_NO] and SequenceNo eq $oSEQUENCE_NO]
