Editor : Just in case, you are wondering what happened to my old technical blog. Here's the link isskythelimit-technical. I had it revised and migrated to this new blog. All my old entries still remains in the old blog. Thanks!
It had been almost half a year since I participated in ECC6.0 roll out at the end of 2008 for EU, the Americas, and Asia Pacific. I was in a team responsible for Asia Pacific region and Germany being the leading team started the roll out at December 2008 with a blast. Things were getting excited and my team had faced a number of challenges but had it solved before the go-live. It was a challenging but wonderful journey. Some of the things I'd learned from the roll out, I list it down as below:
1. Unicode translation need to be taken care of because ECC6 is unicode enabled system. It means all custom reports had to be flagged for UC. It's not all that easy because you need to identified all programs that is not UC enabled prior to 4.6c.
2. Codings in existing customized program, forms, function modules, batches, Idocs and other customized include programs had to be check out for obsolete coding and to be replaced with newer ones especially strings and certain standard function modules.
3. A lot of testing were carried out by our functionals to ensure that all processes and customizations are working fine accordingly as in the old system after stages of migration as in ECC6.0.
4. There was a UC team specifically to handle unicode and language translation on various countries like EU, China and Japan. It was a gruesome task especially tables are language dependent. SUMG is a good TCODE to maintain your translation objects.
5. Migration of development system, quality system and production system are taken stage by stage to ensure, I should say, a smooth upgrade that does not impact the business process or users.
6. Then come after the roll out, the warranty of supporting all users so any unfound errors left in the upgrade process can be iron out. So this is another last wave of support. There after, its back to normal support and development routine.
Six month upgrade project that I had gone through with the team. A good deal of fine functionals and a four person development to support only Asia Pacific region.
