Issue while importing records

Question

Hi MDM Gurus,
I am facing a problem while records are getting imported in MDM. The problem is when I am importing records in MDM it is mixing up the field values if null for the records which have the same match record key.
Eg: I have following data:
in this Mobileno is key field and records are getting imported with the help of this key
Firstname   lastname     Mobile
aaa           bbb             987654321
ccc                             987654321
O/p is produced as follows
Firstname   lastname     Mobileno  
  ccc             bbb            987654321
First name of a person is getting mixed up with last name of another person having the same mobile number as that field is empty while importing. My requirement is it should not overwrite null values or if some values is already there Null values should not overwrite the already present data.
Has anybody come across this problem
Thanks & Regards
Kiran

Answer 1

Hi Ankur,
Mobile number field is unique field in my case. Let me explain you with another eg
Consider the following case where in firsttime the data comes with following record.My unique key in this case is filed1
field1   field2     field3    field4
aaa     bbb        ccc      ddd
MDM stores it as:
field1   field2     field3    field4
aaa     bbb        ccc      ddd
Again data comes in MDM as:
field1   field2     field3    field4
aaa                  fff
it now gets stored up as:
field1   field2     field3    field4
aaa      bbb        fff         ddd
which is creating a problem as data is getting mixed and not getting stored as it comes to MDM.
Thanks & Records
