Hi Priya,
while creating matrix types you are selecting only one relationship A 088 right ? then how can you see the reporting A 002 while display the matrix structure in PPME you are selecting matrix type which is having relationship A 088 only.
no need to give to relationship for any position like A 002 and A 088.
direct manager will get the relationship A 002 and indirect or super senior positions need to give A 088 relationship's. if you want to see the all the reporting manger's for the specific position (trainee) then don't give reporting relationship A 002 directly give A 088 for all the reporting managers. then in the general structure PPSS and matrix strut. PPME will show same positions.
hope you understand the concept of general structure and matrix structure.
