Analysing the diffs of backups before and after adding 1 Customer resulted in a set of INSERT statements when parsed out and sequences with variable extractions done resulted in the following (Assumed TB_PREF=3_):
SET @Customer := "PKA Enterprises";
SET @CustShort := "PKA";
SET @Phone := "28557841";
SET @EMail := "pka@example.com";
SET @Address := "Joe Smith Road\nTimbuktoo - Z9HG34";
SET @GST := "1234578";
SET @Location := 'DEF';
SET @DefCurr := (SELECT `value` FROM `3_sys_prefs` WHERE `name`="curr_default" AND `category`="setup.company");
SET @Credit := (SELECT `value` FROM `3_sys_prefs` WHERE `name`="default_credit_limit" AND `category`="glsetup.customer");
SET @DfPayAc := (SELECT `value` FROM `3_sys_prefs` WHERE `name`="default_prompt_payment_act" AND `category`="glsetup.sales");
SET @PrPayAc := (SELECT `value` FROM `3_sys_prefs` WHERE `name`="default_sales_discount_act" AND `category`="glsetup.sales");
SET @DrsAc := (SELECT `value` FROM `3_sys_prefs` WHERE `name`="debtors_act" AND `category`="glsetup.sales");
INSERT INTO `3_debtors_master` VALUES
(NULL, @Customer, @CustShort, @Address, @GST, @DefCurr, '1', '0', '0', '1', '4', '0', '0', @Credit, '', '0');
SET @DrNum := (SELECT LAST_INSERT_ID());
INSERT INTO `3_cust_branch` VALUES
(NULL, @DrNum, @Customer, @CustShort, @Address, '1', '1', @Location, '1', '', @PrPayAc, @DrsAc, @DfPayAc, '1', @Address, '0', '', NULL, '0');
SET @BranchID := (SELECT LAST_INSERT_ID());
INSERT INTO `3_crm_persons` VALUES
(NULL, @CustShort, @Customer, NULL, @Address, @Phone, NULL, NULL, @EMail, NULL, '', '0');
SET @PersonID := (SELECT LAST_INSERT_ID());
INSERT INTO `3_crm_contacts` VALUES
(NULL, @PersonID, 'cust_branch', 'general', @BranchID),
(NULL, @PersonID, 'customer', 'general', @DrNum);
Here, first a customer is created and then a branch for the said customer.
Then one Person is created.
This Person is then allotted to both - customer and cust_branch.
The above can be useful for bulk importing of customers from disparate systems.
