@ACIJGARRIEPY if you are not expecting to receive EDI messages with prices from your suppliers, then probably you could use the general approval functionality built into Document Management module.
You can read more on this at below page:
Approval Routing (ifs.com)
More specific, for your scenario I would do it the following way:
→ supplier for purchase part set as Inactive immediately after creation → by custom event + approval template created and linked to supplier for purchase part
→ then have another event that would check whenever someone tries to set the sfpp as Active if the approval is 100% completed. Allow part activation only when approval is 100%.
Normally this process requires 2 / 3 custom events and could be used for most of the business objects in IFS.
