Migration from 3.x to 7.x - Error handling type: communication structure​


Hello Community,

I want to migrate 3.x to 7.x Data Sources. During this process I faced the following error message in the migrate log.

"Communication structure is still in use"

The help-info from SAP recommends to:

"Find the uses of the DDIC structure v1 with the where-used list in transaction SE11 and replace them.
Once all the uses have been removed, you can delete the 3.x InfoSource and the communication structure."

The problem I'm facing right now is that there is actually no possibility to remove any of the uses of the DDIC structure. But I can remove the communication structure, even if it's still in use.

I'm not sure if simply deleting the communication structure is a good way to handle this error. So I'm kinda afraid, that simply deleting the communication structure (without removing the uses) will harm the migration output (e.g. that I lose my transformation connnections)

Can someone help me pls.
