Hi Jose, nice to see you fighting with solman also ;-)
I just check on one of our systems, and we have a more field update with sold-to-party, in that system I don't have the technical monitoring so I can't check if it can be solved with that fields.
I see that there is a tab for update the sol-to-party on a different levels, technical system, product system, logical component header and logical component instance.
Check if all that fields are update, i hope that can solve your problem.
I found time ago that on the logical component, there is a problem and the BP ( sold-to-party ) are not stored correctly after click on save button, tell me if you found that and I will search the SAP Note that solve that problem. I also will check that on another system where technical monitoring is running to check if there is a problem like you.
Big hugs Friend Jose,
