RE: Journal Entry and Approval Portal
Hey Nikolaos:
Integration Manager takes your source and imports them into the GP company you are signed onto. With 12 companies, you are looking at 12 iterations of the same.
There is an ISV solution called smartconnect that you can use to load entries from various sources into companies without having to be signed onto GP. They use what is called maps. You could add subsequent imports to run one after the other. Also the import can be scheduled.
As far as approvals are concerned, I need further information, are you looking to approve a batch of entries in a given company? If yes, you could keep it simple by completing a password required prior to posting at a batch level found in the Posting setup.
You may want to contact Binary Stream another ISV vendor - They may have consolidated approvals and do multi-entity management.
Best of luck
