have you considered linking on another table occurrence of Table 2?
You could filter the data to the second portal by setting a new, Global field named "Success" in the main table and have it contain the value "YES".
The new TO would then by linked by the same relationship the other TO has AND by the "Success" field. Linkage will now only occur for those lends which are in your first portal AND were successful.
In this way you could also use the same fields in both portals and keep life a little simpler.
Would this work for you?
