What are the list of all possible values?
From DMD tool under "7292 - Taiwan Stock Exchange Corporation (TWSE) Equities [TRDFD/Legacy] (Domain = MP)" :
But from the RDFD FID list document :
Value 63 is missing from FID 118 in the RDFD FID list document while DMD tool has 63 in FID 118.
Which is right?
To see a list of all possible values for that field regardless of exchange, search a recent enumtype.def file for PRC_QL_CD.
Your Market data team should be able to provide a recent enumtype.def file OR you can refer to the following post Latest dictionary files
IF, however, you want to know specifically which values apply to TSE then you will need to raise a Content type ticket and discuss with a content specialist - this forum is more suited to API type queries.
