Hey @volkswagner, that’s a great reference, thank you for that.
I think I have missed that very recent thread when I was searching in the web and in this forum. To me it is quite hard to know the relevant keywords used in other countries that may refer to the same concept in ours. In this case I noticed that Employer Contributions is the key term.
Back to the issue, I think I’m using the same approach described by @peterg here and that you tried there.
I have to implement an extra server script as here in Colombia, we need to track the specific organization the employee has chosen for every contributions. All it does it to set the Party in the payables (And in the expenses, which may not be something ERPNext expects, though) so when can use the standard reports of ERPNext to query the information.
My real issue here is that when paying those contributions, they are not reconciled. Then I must be missing something here.
Again, thank you @volkswagner for taking the time to respond and your references.
