Hi,
Please help me!
SunSystems application working with MS SQl, and we want to this database tabes convet to for 1C, so how can convert sunsystems database to 1c database?
1C database will be MS SQL.

You can convert.
First you have to create your database here.
You can then retrieve the records by contacting External Link.
If you are using a private ID, your job is very simple.
If the database table uses the default PRIMARY ID, you need to write custom code.
I do not think it's too hard.
