Many to many filter by common one entity

[artur]

Multi-link: One S has Many SP. One S has Many C.
How to make a filter so when user is on C the user may select only those SP which have the same S as this C have?
Advanced pack is installed so filters can be created i.e. from reports if needed.

Hi artur,

This can only be achieved by modifying the code. The similar issue was discussed here: https://forum.espocrm.com/forum/deve...tionship-value.
