What are the best practices to delete DMW and LSH objects?


For example, if you are using a Template for your Study, and you need to delete some models/objects from there, you may hit unexpected errors like:

1. DMW-<NNN>: ERROR: An unexpected error occurred while processing the data. Please try again. If the error persists please contact the system administrator.

2. DMW-<NNN>: Returned Status: U Msg:null. DB-API must return exception

3. DMW-<NNN>: Multiple Exceptions thrown
DMW-<NNN>: ORA-01403: no data found in Package doOperation Procedure DME_DF_XFORM_MAP

DMW-<NNN>: SQL Error Occurred ORA-ERR No : ORA-01403: no data found, Function Name : doOperation, Package Name : DME_DF_XFORM_MAP. Please contact your System Administrator.


When you delete some objects on LSH, you may hit errors as below:

XFM_INSTALL:15-JAN-18 22:03:51:Object Name cannot begin with a TILDE (~).
Please remove the TILDE character and proceed.
Error from OWB/CDR DB Server-PLSQL Operator: statement:"begin
caught:java.sql.SQLException: ORA-06510: PL/SQL: unhandled user-defined
ORA-06512: at "APPS.DME_INST_XFORM_MAP", line 10070

ORA-06512: at "CDR_WE19_1B5E41_1.PLSQL_UTIL_PROG_PKG", line 4
ORA-06512: at line 1


Other symptom you may notice is some object names will include a tilde at the beginning (~). This tilde is harmless, but it can help you to detect if an object was deleted. For example, you may see tildes in front of the Tables name in Production lifecycle.
