Data overwrite in Master data

[Former Member]

Hi,

I'm loading data for master data for InfoObject X (with attributes A,B,C and D) from 3 non-sap sources. I had these questions. The key field here is infoobject X itself:

1) Will the data gets overwritten, if same keyfield come from two source systems?

2) I'm thinking of incorporating 0SOURSYSTEM as one of the attribute as well to avoid such a situation, so should I also make 0SOURSYSTEM as the key field?

Hi,

But are you sure that the number range in all the 3 source systems were same.. if not you can maintain source system as an attribute rather than as Compounding Attribute.

If the values are same then why do you think attributes are different across source systems.

Either the Key is different or the attribute values are the same.

Check with Source system functional or business anlayst and then plan. Source System as a compounding attribute is not advisable.
