Compare infoobjects from 2 different cubes in the query

Hello everybody

I have a problem

I have a CUBE 1 - it contains  the infoobject " INV_ID".

2 additional Infoobjects " INV_TYP", "INV_NAME" must always be filled for a given INV_ID.

Example: CUBE 1

INV_ID     - INV_TYP - INV_NAME

X123          XYZ              TEST

X456          ABC               DUMMY

I have a second cube CUBE 2 and it contains the same objects as above and should get the same results , for a given INV_ID , INV_TYP", "INV_NAME" must always be filled and in the same way as in cube 1 .

Unfortunately this is not the case and the results are not homogeneous.

Example: CUBE 2

INV_ID     - INV_TYP - INV_NAME

X123          UWW             TEST

X456          ABC               CHECK

same ID - diffent results that ´s wrong

How can I build a report with the query designer where I can see the differences?

I have no common Key figures for the 2 cubes.

thanks in advance for your help

best regards
