Hi,
So basically my requirement is to map the No. field on the Customer form in Business Central with the Account Number field on the Account Form in Dynamics CRM when the integration takes place and the data gets synced.
Below are the fields from both the respective apps
Account Number from Dynamics CRM

No. from the Customer form in Business Central

However doing some research did bring me to this window below where you can see the mappings of the respective entity and even download an excel sheet to edit the same
And once you download the excel file and open it you will see a Dynamics CRM connector getting downloaded and then after you sign in to your correct environment then there's the list of mappings as below

But there few problems/concerns around this
- To edit this downloaded excel sheet one must have Office 2016.
- To add the custom mappings here one must be aware of the field numbers in both the apps as there are no field names in the sheet even though they are shown when in Business Central. So I am not very sure from where to find these field numbers.
- Isn't there any way to add mapping online?
Not sure if I am missing out on something, but any help or suggestion is highly appreciated and would be of great great help.
Thanks!
