Dear All,
I would like to share below checklist which helped me to remind of doing things before starting SUM tool while working with multiple systems in a upgrade project. After reading ECC EHP6 master guide, SUM guide, Upgrade guide and recommended SAP notes from service marketplace which is obvious separate guides and notes which I have downloaded on my disk for reference. But I needed something handy for each phase which I can print and stick it to my desk so I have created a master document in which I have created multiple sheets like below :
Master Document :
- High Level Technical Plan - Sharing / Updating this sheet weekly and sending across client steering committee for Project update
- Detail Technical Plan - A pure tech plan sheet mixed of above mentioned guides & SAP Notes
- Planning & Preparation - Checklist before starting SUM tool
- Solman Specific - Technical steps from adding system to LMDB/SMSY till STACK file generation
- Execution & Postwork - Execution phases are actual SUM phases like Initialization, Extraction, Configuration etc., and Postwork steps
- SAPNotes for reference & Monitoring log files path - Details from SAP notes like keyword from note: 1790828, Increase DB process in case of error in Preprocessing phase refer note : 34432.
Below is the example of Planning & Preparation sheet I will try correct and post remaining sheets from above document soon.
