Formula is invalid : Incorrect formula: 'if(RX_MDM_PARTY_ID == "UNSP", isBlank("RX_MDM_PARTY_ID") , "MDM_PARTY_ID" if(RX_MDM_PARTY_ID))) ' 
 
Thanks

Hi,

the or operator is || . So maybe you're looking for 

if (MDM_PARTY_ID == "UNSP" || isnull(MDM_PARTY_ID), RX_MDM_PARTY_ID, MDM_PARTY_ID)

You can also do it visually with a clear cell where value is UNSP then a formula with a coalesce()
