Error calling a method of the tree control in BDC

Former Member

I'm connecting two systems Iplan(project management tool) with SAP PS using SAP XI.

I've written an BDC(RFC) to assign people for the activity in an project(cj20n) it works fine in the foreground. But it doesn't work in the background.It doesn't give me error also.I've sap all authorization.

When I connect with XI its throwing me an error "Error calling a method of the tree control" message type A (using the same user to connect r3). I believe something we should do prior handling the tree control in a BDC. IF any body come across this situation please let me know. your help is appreciated.

BDCs over enjoy transactions do not get along together. The containers and controls is more of a gui thing, and in background sometimes the BDC has a hard time with them. I would suggest using the non-enjoy tcode instead, CJ20.
