Hi Vinutha,
Once you have maintained the marketing attributes can you check it out once in BP transaction if the values are coming up or not ? I tried to maintain the MKT attributes using the FM CRM_MKTBP_ASSIGN_ATTRIBUT_TAB and it worked fine it gave me all the values . The marketing attributes have an attribute set and this has to be maintained in SPRO once it is done it would be the same for GUI and WEBUI . If the STD code is checking only the first value then the configuration has not been maintained or the view of the marketing attribute is allowing only one value we can check that in the HTML page of the view or we need to implement something so that all values come up . The other thing is for a marketing attribute there will be an attribute set and over there we maintain the values for it .
