Computed Column at publisher end not replicating at subscriber end

Hi I do have Publisher Tableand Subscriber Table, both has same schema, Difference is publisher table has one computed column which return varchar Like Sample Below:
CREATEFUNCTION[cimfn_FormPartition](@pKeyVal BIGINT)
    RETURNS VARCHAR(100)WITH SCHEMABINDINGASBEGIN[LOGIC]RETURN@OutputEND
    GO**Publisher End:**createtable table1([pKey][bigint]IDENTITY(1,1)NOTNULL,[cKey]AS dbo.cimfn_FormPartition(pKey) PERSISTED,[id][varchar](20)NULL,[refId][varchar](20)NULL,constraint[pKey]PRIMARYKEYNONCLUSTERED( pKey ASC))ALTERTABLE[table1]ADDCONSTRAINT[CI_Items]UNIQUECLUSTERED([cKey])ON[PRIMARY]**Subscriber End:**createtable table1([pKey][bigint]NOTNULL,[cKey][varchar](100)NULL,[id][varchar](20)NULL,[refId][varchar](20)NULL,constraint[pKey]PRIMARYKEYNONCLUSTERED( pKey ASC))ALTERTABLE[table1]ADDCONSTRAINT[CI_Items]UNIQUECLUSTERED([cKey])ON[PRIMARY]
In the Article Properties of publisher tableAll things I have setto false ,andset ACTION IF NAME ISINUSE: Keep existing object unchangedWhen I insert data into publisher tablethenin subscriber tabel I am getting below output :**pKey cKey id	 refId1NULL  Item1	i1**
I Have addedd Article Proper and Even though subscription tableis  getting null value in cKey ,andall other column has correct value.
I have checkreplication monitor as well , No error is showing there.
I more drilled down with the store procedure**(sp_browsereplcmds)**and found out the insert command does not have computed column value with this. So now again question is why Distributor isnot picking computed columnfrom publisher?
