I know I am missing something simple here. I have a portal on a layout that allows the user to enter test data. SN, result!, result2, result3, etc.
I have the portal relationship set up to allow creation of records in the Data table and linked by MasterID and PortalID. For layouts that use more than one portal there are separate TOs of Data for each portal and PortalID is set by global fields for 1, 2 or 3 depending on the TO used.
The issue is the one layout I have so far that uses only 1 portal allows creation of a new record in Data, but as soon as that record is commited the portal shows 2 rows with that data and will not allow creation of another.
I have another layout that has 2 portals and it is working as expected.
