I am experience a decode issue , When i take a look at the Calling Party Address in SCCP message. It showed ,PC=7420,ssn is unknown ,the code showed 43 fc 1c 73 02, it should decode like 02-73-1c,ssn=252,check the preference of MTP3 already modify to ANSI.

Not sure how to fix this issue.

Hmmm, if it is showing you "PC=7420" then it really looks like the MTP3 dissector thinks it is running ITU.

Oh, well, the other problem (if this is supposed to be ANSI) is that the high-order ("reserved for national use") bit in the Address Indicator is not set. That means, in ANSI, that the address is coded to international (meaning: not ANSI) standards. If you're using a modern Wireshark there should be an expert info warning about the unusualness of that...

I suspect that's the problem: either it's not really ANSI or that high-order bit is wrong.
