Assembly Processing: Message Create network: Project Allocation

Hi Experts,

We have an issue here where have been using Assembly processing. Now we are extending the process to new company code.

CN09 has been maintained

But when saving the quote we get this error message

The material being used is mapped to Std project 53100059 , but not sure why its showing the below screen and two Std ProjDef.

When I try to cancel it gives another message " Enter a CO Area, company code, or plant"

and then it gives message "error when processing network" and kicks out of the document.

Appreciate if you have any suggestions.

Regards,

Krishna
