rdisp/rfc_max_own_login 
With this parameter you can set the cut-off value for the number of own logons in the SAP system. It is different from the parameter rdisp/rfc_max_login in that in this case, it is the logons of one user only that may not exceed the quota.
This value is, therefore, a percentage of rdisp/tm_max_no. It restricts the logons of an (RFC) user and thus prevents a program from sending RFCs to such a degree that other (RFC) users cannot log on to that server.
Caution
This parameter is valid only if the check is run locally. If the check is carried out on a remote server, the parameter is ignored and the next more restrictive quota takes effect. You can find details of the different checks in Resource Determination for Asynchronous and transactional RFC.
Prerequisites
The RFC resource check is active (see rdisp/rfc_use_quotas = 1).

SAP Recommendation
Example
If you want to allow that one application is assigned the entire RFC resources of a server, you have to increase the parameter. You could increase it to the value of rdisp/rfc_max_login, for example.
