Other notes to prepare for the integration:
- standard synergy set-ups should be included prior to integration, these would include currencies, financial periods, payment conditions (ar/ap terms), item assortments, HRM records, CRM set-ups
- legacy data - as suggested, cleaning the data is advisable. This would also include consistency in entry of state/province codes, country codes, etc. This will not only decrease the need for translations within the integrator, it will be a good opportunity to clean up progression and remind employees of the importance of consistency in data entry (makes for easier report writing for Progression, too)
- thought and planning must go into the decision of how to manage "ship to addresses". Ship to's can either be integrated into synergy as contacts beneath an account, or as child accounts of the parent. There are pros and cons either way, but my recommendation is to map them to parent/child relationships. I can expand on this if required, but I am sure your implementor can address this.
- Likewise, careful planning should be done in regards to account, contact, item free fields prior to integration.
- depending on the level of GL reporting desired in synergy, you may wish to adjust the GL sub-types on your progression Chart of Accounts
- finally, key note: do not go gung ho entering other data into the live system prior to completing your initial integration. Finalize the mappings and initial data load first.
Integrator is running well (yes, this includes AR docs)- support from Andover team is excellent and there are always consultants willing to offer knowledge and experience.
