Dear Kadir,
I have given alternate method apart from IE.
1) Have excel file with customer and relevant fields.
2) Install eConnect for Dynamics GP.
3) Copy the below code
EXEC [dbo].[taUpdateCreateCustomerRcd]
@i_vCUSTNMBR = 'CUST001',
@I_vCUSTCLAS = 'CLASS001',
@I_vADRSCODE = 'PRIMARY',
@I_vADDRESS1 = 'Address1',
@I_vADDRESS2 = 'Address2',
@I_vADDRESS3 = 'Address3',
@I_vToEmail_Recipient = 'Nattis@demoinc.com',
@I_vUpdateIfExists = 1, --Flag to allow customer data to be updated if it exists
@O_iErrorState = 0,
@oErrString = ''
4) Using mail merge, map the corresponding fields. run via SQL.
4) Once executed, please verify in GP
Note: Please run it in UAT before proceeding to LIVE. Also take prior backup to proceed.
You can do the same via GP macro also.
Thanks,
