Answer 1

hi,
I will list out few of critical issues in
Implementation :
1 . Ensure 100% mapping of business process for all modules with SAP(avoid customization in support phase)
2.  Unit & Integeration testing should be through with all validations
3.  Master datas(Vendor,Customer) care must be taken will uploading datas thru LSMW,
If there are common vendors for all plants,Create a vendor for a plant extend it to other plants
4. Check tax procedures are customized according to requirements.
5. Complete all print document customizations before go live
6. Complete end user training(2 or more cycles) should be top priority before go live(This will avoid
cancellation/reversal of documents after post go live)
7. Ready with standard MIS reports & customized reports for business decision making
8. Excise opening balance updation in tables for RG1 register in tables(Note 951955) on go live
9. Check all tables datas are updating correctly
10. Declare go live to SAP Support
11. Check All user authorization should be correct according to their roles.
12. Centeralize all master datas creation(avoid duplication)
13. Create transaction variants to avoid entires in unnecessary fields & make certain fields mandatory.
14. Ensure document numbering is completed for all documents
15. Validate accounting entries are hit properly according to requirement in quality client with FI CTM(Core team member).
After Go live :
1. Missing authorization for users will play key part here,For ex : PGI while doing delivery,Excise capture & post in MIGO/J1IEX.
2. Do internal audit every month,identify transactions if there will possibility for misuse or wrong entries,requires validation,identify users weak in certain areas.
3. Identify there is enhancements to be done in transaction process(By step-2)
4. Prepare a list of month & year end activities to be performed for all modules give to users
5. Prepare  a list of frequently used transaction codes module wise give it to users
6. If there is subcontracting,ensure challan creation,GR,reconcillation should be done regulary(monthly)
7. Train the users,take reports in respective modules.
8. Additonal customization might be done in print documents.
9. Instruct users/CTM's to adapt SAP Standard practise
10. Update excise tax rates after every indian budget
Hope it helps.
