ProcessdpCommandEx error when adding or removing object from WebI report (based on BEX query) query panel object list

Hi,

We have WebI reports build on BEX using BAPI connectivity. When we are trying to add a object in query panel in a existing report we are getting this ProcessdpCommandEx error. But error does not appear when we add at the end of the list of objects already added.

Can you calrify whether this could be some setting issue or it is a known bug?

Can you share SAP Note No in case it is a known bug?
