TN not recognizing ISA05 value = 30, but does recognize ZZ: Interchange ID Qualifier

I have multple partners sending us an EDI, and when one partner sends the EDI with ISA05(Interchange ID Qualifier) = ZZ it works, but when other partner sends the EDI with ISA05 = 30 it gives and error: Invalid Sender ID [EDIFTN.000010.000233]

How to handle this scenerio.

Please help.


The value of ISA05 must correspond to the proper TN profile external ID type. Refer to the EDI docs for details.
