Migrate from ABRA Gen to Epicor Prophet 21

ABRA Gen firmy records store both customer and supplier entities in a single table distinguished by a type field. We split firmy into Epicor Customer (for accounts receivable) and Supplier (for accounts payable) during the transform phase. Address, contact, payment-term, and banking-detail fields map to Epicor's Customer and Supplier records, with the ABRA Gen firmy code preserved in the legacy ID field for cross-reference.

ABRA Gen odberatele records are a subset of firmy scoped to sales-facing entities. We map these to Epicor Customer, preserving billing and shipping addresses as ShipTo records under the parent Customer. Customer credit limits, payment terms, and price lists carry forward as configuration data in Epicor's Credit Check and AR setup.

ABRA Gen dodavatele records map to Epicor Supplier. We preserve vendor codes, payment terms, and any vendor-specific discount structures. Banking details for SEPA or wire transfers map to Epicor SupplierBankAcct records. Multi-address vendors get multiple SupplierPayment records in Epicor.

ABRA Gen zakazky capture project-level financial tracking, cost allocation, and billing. We map these to Epicor Job records for manufacturing execution and to Project records for job costing. Job codes and contract numbers carry forward as Epicor JobNum and ProjectID. Any nested hierarchy in ABRA Gen zakazky resolves to Epicor's JobMtl and JobOper multi-level structure.

ABRA Gen sklady define stock locations with warehouse codes, bin structures, and on-hand quantities. We map warehouse codes to Epicor Warehse records and create corresponding PartBin entries for on-hand quantities. Serialized and lot-controlled inventory is flagged during discovery and mapped to Epicor's PartLot and PartBin serial-tracking fields. Multiple ABRA Gen warehouse types map to Epicor's multi-warehouse and multi-bin configuration.

ABRA Gen vyrobky store product master records with pricing, unit-of-measure definitions, and BOM structures. We map to Epicor Part with PartNumber, Description, ClassID, and UnitOfMeasure. Multi-level BOMs from ABRA Gen are flattened into Epicor's PartRev (revision) and JobMtl structure with the correct quantity-per and operation sequences. Stocking types (finished goods, raw material, work in process) map to Epicor TypeCode.

ABRA Gen ucetni records are Czech accounting journal entries with COA codes, tax codes, and posting dates. We map account codes to the destination Epicor COA, preserving document-level detail and debit/credit amounts in Epicor's GLJrnHed and GLJrnLine tables. Fiscal year segments and cost-center codes resolve to Epicor GL Account segments. Audit trail dates and voucher numbers carry forward for the required retention period (5-10 years under Czech and Slovak law).

ABRA Gen doklady store sales invoices, purchase invoices, delivery notes, and credit memos as document headers with line items. We map open and recent historical documents to Epicor ARInvcHead/APInvcHead with line items to ARInvcDtl/APInvcDtl. The ISDOC XML format that ABRA Gen produces natively maps to Epicor document references stored in the Attachment table, and ISDOC invoice numbers map to InvoiceNum fields. Documents with posting dates outside the migration window are flagged for customer decision on archive versus load.

ABRA Gen uzivatele records map to Epicor User accounts and UserComp company-access records. Role and permission-set data from ABRA Gen maps to Epicor's menu-security model during configuration. Inactive ABRA Gen users are held in a reconciliation queue and deactivated at cutover. Active users are matched by email or username for Epicor User provisioning.

ABRA Gen zamestnanci records hold employment data for HR and payroll integration. We map employment status, department assignment, and contact data to Epicor Employee records. Department codes from ABRA Gen resolve to Epicor's DcdLbrGrp and DcdShift cost-center configuration. Any HR or payroll data held in ABRA Gen maps to Employee fields, though ERP-integrated payroll may require a separate HRMS integration scope.

ABRA Gen natively produces invoices in the ISDOC/ISDOCx electronic format defined by the Czech SPIS/ICT Unie working group. We map ISDOC invoice headers and line items to Epicor ARInvcHead and ARInvcDtl, and preserve the original ISDOC XML as an Epicor Attachment linked to the invoice record. Customers using ABRA Gen's ISDOC export for Czech e-invoicing compliance confirm the replacement format in Epicor's Electronic Invoice configuration before migration.

ABRA Gen firmy records support multiple address records per entity (billing, shipping, branch). We split these into Epicor ShipTo records under Customer and SupplierPayment address records under Supplier, with address type codes preserved as ShipToNum or SupplierNum references. The primary address designation from ABRA Gen becomes the default ShipTo in Epicor.
