MRC Implementaion on Existing Environment???

What is MRC?

MRC allows Oracle Applications to support organizations that are transitioning from their national currency (Functional Currency) to other Currencies Supported by Oracle.

Is the process of converting functional currency into other currency during reporting.

Modules Impacted With MRC

General Ledger
Account Payables
Account Receivables
Fixed Assets etc.

How do I Enable MRC
STEPS TO BE FOLLOWED:

Installing MRC with Invokers Rights On( This is for New Installation).
Set Up Environment and Database.
Compile and Validate APPS Schemas.
Convert to Multiple Reporting Currencies.
Verify the Installation.
Perform Post–Installation Steps.
Maintain MRC Schema Objects

Running adadmin

Login to FE Node (elephant)
Run adadmin
Filename [adadmin.log] : adadmin_dv1_mrc.log
Please enter the batchsize [1000] : 100000
Enter the password for your 'SYSTEM' ORACLE schema:
Enter the ORACLE password of Application Object Library [APPS]
4. Maintain Applications Database Entities menu
1. Validate APPS schema
This will generate APPS.lst @ $APPL_TOP/admin/SID/out/APPS.lst

Sample Summary of Issues and Proposed Fixes Reported by APPS.lst

Objects with the same name as schema
Proposed Fix: Dropping all objects
Invalid Synonyms in APPS
Proposed Fix: Drop & Recreate all ,drop which are still invalid as reported by validate APPS.
missing or incorrect synonyms in "APPS"
Proposed Fix : Repointed the missing and incorrect synonyms
Missing Grants
Proposed Fix: Grant will be given to the reported objects.
Missing Privileges/ synonyms to objects not in "APPS" base schemas - 2586
Proposed Fix: Grants will be given
Invalid Objects
Proposed Fix: If Close to production. The objects will be documented and the results verified post MRC Installation.

Code Objects in the Base Schema - (Recommended but not mandatory)
Proposed Fix: No Action
Tables exist both in APPS & Base Schema
Proposed Fix: Compare in production & dropped.
Checking for packages in "APPS" with lines > 255 characters
Proposed Fix: Breaking the lines having more than 255 chars.
Checking for missing/invalid APPS_DDL or APPS_ARRAY_DDL packages
Proposed Fix: DBA will address this.

Different issues

Incorrect synonym:
APPS.MSD_APP_INSTANCE_ORGS- should point toMRP.MSD_APP_INSTANCE_ORGS.Incorrect

Synonym Pointing to Remote Objects with DB Link

Synomyms Pointing to Objects which is Invalid.

Synomyms pointing to Objects which does not exist.

Application Schema not having standard packages like APPS_ARRAY_DDL and APPS_DDL

Similar table object exists in two different schemas.

Necessary grants are not given from Custom Apps schema to APPS.

Package line length more than 255 chars

Invalid Objects

Enabling MRC through adadmin

Run adadmin
4. Maintain Applications Database Entities menu
5. Convert to Multiple Reporting Currencies
Enter SYSTEM password
Enter the number of workers [64] : 24

Converting to Multiple Reporting Currencies (MRC) will create
one extra schema per APPS schema in your database.

Each MRC schema requires about 600 Megabytes of free space in your
SYSTEM tablespace and takes from 6 to 18 hours to create.

You must not perform any DDL operations on your Oracle Applications
database while converting to MRC, but you may change data.
