Can't remove document from service call expenses

Hi All,

We just upgrade to SAP B1 9.2 PL3 (32-bits) recently, just realized that we can't remove document added into Expenses of a service call even the document are still open and no transaction. Not sure if this issue is brought by the recent upgrade because we don't have old version anymore. Here is what I did:

1. Create a service call and attach an AR document (SO) in its Expenses tab

2. Save the service call.

3. Reopen the service call and go to Expenses tab, right click the document and choose delete row. But it doesn't work.

There is no error message at all, but it just doesn't remove the document row.

Any idea?

Thanks!
