Experience with Integrating Primavera Schedule Activities with CBS

Question

Hi @everyone

I wanted to share something I’ve been experimenting with lately regarding the integration between Primavera P6 schedules and the ineigh Control Module—specifically around aligning the activity structure with the Cost Breakdown Structure (CBS).

I’m currently testing an approach where I use Activity Codes in Primavera as my WBS/CBS framework. The idea is that this creates a cleaner, more consistent mapping when exporting the XER file and integrating it back into the ineigh control module. So far, it seems to simplify the alignment between schedule activities and cost elements.

I’m curious to hear from others who’ve gone through this integration process:

* Have you tried integrating an XER file directly with the Control Module?
* From your experience, is it more reliable to use the Activity ID or Activity Codes as the primary integration point?

Any insights, lessons learned, or pitfalls to avoid would be really valuable for anyone working on schedule‑cost alignment.

Looking forward to your thoughts and experiences

I’m not facing any issues with many‑to‑many relationships. The activity codes are unique, and multiple activities can be assigned to a single code. The mapping between each activity code and the CBS is strictly one‑to‑one

I'm always interested in hearing how to better align WBS with CBS (not to mention the estimate and pay items).

Don't you have an issue with many-to-many relationships? How do you plan to address this?
