INTRODUCTION
In this document we try to comprehensively cover the SAP Go live strategy.
The Go Live strategy comprises of the following:-
1) Cut off procedure
2) Pre- Go live checks.
What is meant by cut off date?
SAP system is configured as per the requirement of the client. The system is
ready for the client to use. The client now needs to migrate from the Old system
(Legacy system) to the new SAP system.
The migration from the old system to the new system is known as cut off date.
The old system is switched off and the new SAP system is switched on.
The data will be migrated from the old system to SAP. The data will henceforth
be entered in the new SAP system.
To have a smooth switch over from the Legacy system to the new SAP systems
are devised the cut off procedure
What is meant by Pre u2013 Go live check?
It is ensuring that SAP Production system is ready to go live smoothly.
Letu2019s proceed then.
Scenario
A Ltd. is a company implementing SAP system.
The company follows a January - December period for preparing financial
accounts.
Therefore the go live data decided for A Ltd is 2nd January 2006.
The Trial balance will be uploaded with date as on 31st December 2005.
The Trial balance will consist only of balance sheet items since all the expense
items are already transferred to the retained earnings account in the old system.
The activities are divided as follows:-
1) Pre Go live activities
A Ltd will upload the GL codes, cost ele ments in the production system on 1st
December 2005.
A Ltd will complete upload of all the material masters with all the views in the
production system by 2nd December 2005.
All Bill of Material, Routings will be uploaded in the production system by 4th
Decemeber 2005.
The material masters for raw and packing material will be uploaded with the
moving average prices on 4th December 2005.
The cost center Plan will be uploaded, allocation cycles and activity price
calculation will be done by 6th December 2005.
Product cost calculation will be conducted from 7th Dec 2005 to 20th December
2005 to get the correct cost calculation from system.
All other masters will be uploaded into the production system from 5th December
2005 and completed by 18th December 2005
2) Cut off activities
The company closes it sales on 26th December 2005.
The company stops all its stock movement on 26th December 2005 upto 1st
January 2006.
All open purchase orders will be uploaded on 28th December 2005.
The provision for stock received and invoice not received will be accounted in a
separate GL code (different than the GR/IR)
The stocks will be finalized by 29th December 2005.
The company closes it old (legacy) system on 30th December 2005.
The stocks will be uploaded on 31st December 2005 and 1st Jan 2006.
The standard cost estimate will be marked and released on 2nd January 2006.
The system is available for data entry and operation to the users from 2nd
January 2006.
Accounts Receivable open items will be uploaded from 1st January 2006 to 3rd
January 2006.
Thus Accounts Receivable is available from 4th January 2006 to account for
customer incoming payment.
Accounts Payable open items will be uploaded from 3rd January 2006 to 4th
January 2006.
Accounts Payable is available for payment from 5th January 2006.
Fixed assets are uploaded on 5th January 2006.
The Remaining GL Balances are uploaded on 7th January 2006.
Thus entire data take over activities are to be completed by 7th January 2006
We will divide the activities as follows:-
A) Pre u2013 Go Live activities
B) Pre u2013 Go Live checks
C) Upload transaction data into the system
A) Pre u2013 Go Live activities
1. Master data Load into Production system
Ensure all the master data is loaded into the production system.
We will broadly cover the master data which needs to be loaded and the module
responsible.
Material Master u2013 Basic responsibility MM: All the respective views of the
material masters the other modules responsible . Ensure that all the required
views are uploaded
GL codes - FI
Customer Master - FI (accounting view) and SD (sales view)
Vendor Master - FI (accounting view) and MM (purchasing view)
Cost elements - CO
Secondary cost elements - CO
Profit centers - CO
Cost center - CO
Activity type u2013 CO
Bill of Material u2013 PP
Work Center/ Resource u2013 PP
Routing / Master Recipe u2013 PP
Purchasing Info Record u2013 MM
Service Master - MM
Bank Master - FI
Quality Info Record u2013 QM
Quality Inspection plan
2. Upload Cost center plan
Cost center plan must be updated through transaction code KP06 or using excel
upload.
3. Execute the allocation cycles within cost center
accounting
The plan allocation cycles (distribution, assessment) must be executed within the
cost center accounting module. This will allocate the costs from the service cost
center to the receiver cost center.
4. Update planned activity
After executing of the plan allocation cycles, the production cost centers are now
ready with the planned costs.
You can now calculate the activity prices through the system or manually update
the planned prices by calculating it outside.
The planned activity must be updated through transaction code KP26.
5. Calculate Activity prices
Calculate the activity prices using transaction code KSPI.
6. Execute product costing run
The product costing run will be executed for all semi-finished and finished
materials in the system using transaction code CK40N. This should be run after
all the BOM and Master recipe are uploaded.
The product cost finalization takes a long time and should begin well in advance
before the go live date. Normally the product costing run has to be executed
again and again (3 u2013 4 times) since data needs to be corrected and costs have to
be compared with the existing legacy cost.
The possible errors in the product costing run are:-
1) Moving average prices or planned prices are not correctly maintained in
the material masters
2) Incorrect quantities in the Bill of Materials, incorrect base unit quantity in
the Bill of Material
3) Incorrect quantities (hours, KWH etc) for activities in the Routing or Master
recipe.
4) Incorrect alternate unit of Measure
The product costing is calculated and made ready. The actual Mark and release
will happen on after the stocks are uploaded into the system.
B) Pre u2013 Go Live activities
1. Ensure all the customizing request are in the
production system
Check that all the customizing request are gone in the system and no
major requests are pending. Request relating to reports being developed
can be transported as and when the reports are ready.
2. Ensure all the number ranges for all the modules
have been maintained in the production system
3. Ensure that Operating concern has been generated
4. Ensure that all the Customer Master data is loaded
5. Ensure all material masters (all material types) have
been loaded
6. Ensure that all the Vendor Master data is loaded
C) Upload transaction data into system
1. Upload Open purchase orders
Open purchase orders can well be uploaded into the system in advance
before the cut off date if no invoices are expected.
2. Stock upload
Stock upload happens in 2 steps:-
1) Finished goods: The standard prices are first uploaded through MR21 or
through an ABAP program which also uses MR21. The stock quantities
are uploaded using movement type 561 through an ABAP program which
calls transaction MB1C.
2) Raw Material, packing Material, stores and spare parts: The quantities
and values are uploaded at the same time using an ABAP program which
calls transaction MB1C.
The stock upload will generate the following entry in the system:-
Finished goods stock a/c Debit
Semi-Finished goods stock a/c Debit
Raw Material stock a/c Debit
Packing Material stock a/c Debit
Stores and spares a/c Debit
Data take over Credit
3. Mark and Release the cost estimate
After the stock is uploaded into the system, the standard cost estimate will be
marked and released into the material master using transaction code CK40N.
4. Upload Accounts Receivable and Accounts Payable open
items
The Accounts Receivable and Accounts Payable open items are uploaded
through LSMW which calls transaction code F-02 GL Account posting. The
profit center is captured in the data take over account. Baseline date must be
captured, which will determine aging based on number of days mentioned in the
payment terms.
The accounting entry for Accounts Receivable open item upload is:-
Customer a/c (not GL) Debit
Data takeover a/c Credit
The accounting entry for Accounts Payable open item upload is:-
Data takeover a/c Debit
Vendor a/c (not GL) Credit
5. Asset Master and value upload
Asset Master is a special case of upload where in you upload not only the master
data but also the values. The total cost and accumulated depreciation are also
uploaded at the same time.
This is done through transaction code AS91.
We will explain how it is done.
5.1 The upload of asset master and values through AS91
This upload of asset masters along with the values will not update the FI General
Ledger. The FI u2013 GL entry balance update will be passed through another
transaction.
5.2 Transfer Asset balance into profit center
Once the asset master along with the values is uploaded, the opening balance
for the asset needs to be transferred to profit center.
The asset balances opening balances are transferred into profit center
accounting through transaction code 1KEI.
5.3 Remove the GL codes for asset from 3KEH table
Remove the Asset reconciliation codes from the transaction code 3KEH. This is
required because a manual FI entry will be passed in the next step, which will
duplicate posting into PCA for the assets.
5.4 Update the FI entry for asset through transaction OASV.
We give an example of how a GL entry passed for Fixed asset upload:-
Let us take Plant and Machinery
Plant and Machinery a/c Dr 100,000
Accumulated depreciation a/c Cr 30,000
Data takeover a/c Cr 70,000
5.5 Reinstate the GL codes for asset in 3KEH
After passing the entry for asset upload update the asset reconciliation accounts
in transaction code 3KEH.
6. Upload General Ledger account balances
Finally we upload the remaining General Ledger account balances other than
Fixed Assets, Stock, Accounts Receivable and Accounts Payable. This is again
uploaded through an LSMW program which calls transaction code F-02 GL
Posting.
Let us take an example for the accounting entry passed:-
Data takeover a/c Debit 550,000 (Balancing figure)
Cash a/c Debit 10,000
Bank a/c Debit 50,000
Advances Debit 90,000
Share capital a/c Credit 100,000
Short term Loan a/c Credit 200,000
Long term loan a/c Credit 400,000
The Data takeover will become zero on upload of this entry.
