Challenges First SAP implementation 10 years ago (FI / CO) Many different subcontractors/developers (foreign and domestic) Parallel disjunctive development for T-Com and T-Mobile Complex system landscape
Many customer developed programs/reports Possibility to differentiate between fixed and mobile business after merge (separate Balance sheet and P&L statement) Very tight schedule (6 months) Copyright © Siemens d.d. 2010. All rights reserved.
Siemens IT Solutions and Services Croatia
System analysis System analysis Systems scan with STT Analysis of org. elements, documents, customizing, business data, reports and tables Workshops for all SAP Modules
Results Analysis of all business processes and interfaces to/from SAP system According to workshops results and system analysis ->creation of possible scenarios for implementation Copyright © Siemens d.d. 2010. All rights reserved.
Siemens IT Solutions and Services Croatia
Results of system analysis by STT Organizational elements Huge number of organizational elements Complex organizational structure Different combination of sales org., distribution cannel, sales group, sales office Unused organizational elements 34 plants Different customizing between the company codes
Customer designed programs and tables 300 customer designed tables with company code 761 customer designed programs with company code 8661 program lines with company code Many hard coded program lines with company code HT or M
The system has very high number of customer designed tables and programs which are using the company code. All programs / tables had to be checked, changed and tested. Copyright © Siemens d.d. 2010. All rights reserved.
Siemens IT Solutions and Services Croatia
Harmonization Variant 1 Company code harmonization without historical data Creation of a new company code (T-HT) starting with the new company code in the new fiscal year Benefits Company codes HT and M still existing for historical fiscal years Less data transition needed Only master data has to be copied by STT
Copyright © Siemens d.d. 2010. All rights reserved.
Challenges All existing organizational elements have to copied (plant, controlling area, sales organization, etc.) Existing documents can’t be copied for further processing (returns, correction) Lose document flow Open item transfer All open processes have to be transferred to the new organizational elements (LSMW) Programming for all organizational elements have to checked / changed (Programs in total nearly 3000)
Siemens IT Solutions and Services Croatia
Harmonization Variant 2 Company code harmonization with historical data Merge of company code M into company code HT with all historical data over all fiscal years Benefits Transferring all historical data Cross years reporting possible Using existing organizational elements Company code M does not exist on the system, no false entries are possible No differentiation of data regarding the fiscal year easier transition rules Existing documents can be used as copy template for returns, correction entries, etc.
