So from your errors in the Auth trace file I can see that the User you are using does not have the correct privileges on Object ID 5305743.
So now you need to find the Owner of this object. The owner can be identified by going into HANA Studio and typing the following into the SQL Editor:
Select * from objects where object_oid = '5305743'.
Once you find the owner you will have to get this owner to grant the User SAPERH the correct privilege (CREATE SYNONYM "PPH_MRP_CHECKBUF" FRO _SYS_BIC").
Once you get the Owner of the Object ID 5305743 to Grant this privilege you should be able to move onwards.
