Body

Problem:  
After Upgrading MAXIMO to version 7.6.0.4  we have the following errors when trying to delete an user added object structure via Object Structures Application
BMXAA4187E - The relationship OSLCACTION does not exist for business object MAXINTOBJECT. Verify that the relationship specified in parameter OSLCACTION exists in the Maxrelationship table  

Solution:
You get this issue because Maximo is missing the relationship, OSLCACTION, in the MAXINTOBJECT table.
This issue will be fixed in the future Fix Pack (MIF 7.6.0.5).

When waiting the new fix pack be released, you can use the below work around to solve the problem.

Please follow the below steps to add the missing relationship in the Database Configuration application:
