Using your sample code from earlier the bold string-literal is the 'query' argument:

SELECT *

FROM OPENQUERY([remoteserver],

'SELECT w.ID,

w.[Rdc],

w.[Pby],

w.[Tp],

w.[Mp],

w.[OpC],

w.[PType],

w.[PCde],

w.[RTye],

w.[RCde],

CASE WHEN e.PCde IS NOT NULL THEN ''Yes''

WHEN e.pCde IS NULL THEN ''No''

END AS [Rts],

COALESCE(re.RSs, ''hold'') AS RStts

FROM (

SELECT *

FROM mydb.dbo.rdw

WHERE PType = ''T''

) w

LEFT JOIN mydb.dbo.caur e ON w.PCde = e.PCde

AND w.RCde = e.rCde

AND w.PTpe = e.PTpe

LEFT JOIN mydb.dbo.revv re ON w.Id = re.rDsId');

EDIT: forum cross-post edited this somehow...putting the furniture back...
