Cannot drop DB2 stored procedure due to undefined name error

I have a stored procedure for DB2. I'm unable to drop the procedure. I'm getting the below error while executing the DROP PROCEDURE <PROCEDURE_NAME> command.

Error:

DB2 SQL Error: SQLCODE=-204, SQLSTATE=42704, SQLERRMC=MYSCHEMA.MyProcedure, DRIVER=3.50.152 Message: "MYSCHEMA.MyProcedure" is an undefined name. SQLCODE=-204, SQLSTATE=42704, DRIVER=3.50.152

Procedure details:

• ROUTINESCHEMA: MYSCHEMA
• ROUTINENAME: MyProcedure
• ROUTINETYPE: P
• OWNER: ROLEA

Command executed:

DROP PROCEDURE MYSCHEMA.MyProcedure;

Error:

"MYSCHEMA.MyProcedure" is an undefined name. SQLCODE=-204, SQLSTATE=42704, DRIVER=3.50.152

Additional information:

• The procedure exists in the ROUTINESCHEMA MYSCHEMA.
• My procedure has no definition
• Unable to view the stored procedure. When I try to open it in the editor, I get an 'object not found' error.

Question

Why am I getting this error and how can I successfully drop the procedure?

DB2 is generally case-sensitive and folds ordinary identifiers to uppercase. Use, delimited identifiers to keep the exact capitalization:

DROP PROCEDURE MY_SCHEMA."MyProcedure";
