Proposed workflow

Customer reporting workflow

Planning example. Stacksync support for the required connection and record operations needs a technical review.

Starting eventA change involving the proposed customer table in Apache Cassandra or Plex ERP Customers needs a defined result in the other system.

  1. Start with the proposed customer table in Apache Cassandra and Plex ERP Customers. Use the record-matching and field-ownership rules from your mapping worksheet.

  2. Resolve person or company type, legal entity, business role, and any billing account before transactions.

  3. Test a normal update and one failed or repeated update in the supported direction. Keep both record IDs with the test results.

What to verifyTest an individual buyer, a company buyer, and one company with multiple billing relationships. Do not merge these into a single generic contact.

Compare integration approaches

Choose a method around one example record and the update your business needs. Use Proposed customer table in Apache Cassandra (choose its name) / Customers to review record matching and confirm Stacksync support for the required operations. Compare ongoing sync, a custom workflow, and a scheduled export against that requirement.

Stacksync managed sync

Best fit
Review compatibility with a Stacksync engineer using an example of the records and updates you need.
Operating responsibility
Fits ongoing record synchronization when the required operations are supported. Add workflow steps for approvals or business actions that go beyond copying fields.
Before you choose
Check record matching: Determine whether each customer represents an individual, a company, or a business-unit relationship before matching it to a contact or organization. Retain the source customer ID and destination ID; names and email alone are insufficient. Verify field coverage, deletion handling, and how changes are detected.

Native vendor integration

Best fit
A vendor-built integration may fit if it supports your Apache Cassandra and Plex ERP record types.
Operating responsibility
Can reduce setup for a supported workflow. You may need another method for records or business steps it does not cover.
Before you choose
First check whether either vendor offers this integration. If available, verify Proposed customer table in Apache Cassandra (choose its name) / Customers, update direction, account tier, and related-record handling.

Custom API or workflow

Best fit
Consider when Apache Cassandra and Plex ERP need a transformation, approval, or action outside a direct record sync.
Operating responsibility
Provides control over business steps; the team owns credentials, version changes, error queues, and reconciliation.
Before you choose
Verify endpoint permissions, pagination, quotas, duplicate detection, and failure recovery. Separate reading history from actions that send messages, grant access, or post transactions.

File or scheduled snapshot

Best fit
Consider for a one-time Apache Cassandra / Plex ERP migration or a reporting need with an explicit freshness window.
Operating responsibility
Can simplify a bounded transfer; later changes and deletion history require another extraction or a separately designed incremental process.
Before you choose
Record the extraction cutoff, source IDs, encoding, date/number formats, and reconciliation totals.

Workflow scenarios and expected results

Customer reporting workflow

Planning example. Stacksync support for the required connection and record operations needs a technical review.

Starting event: A change to the selected Proposed customer table in Apache Cassandra (choose its name) or Customers record needs a defined result in the other system.

  1. Start with Apache Cassandra Proposed customer table in Apache Cassandra (choose its name) and Plex ERP Customers. Use the record-matching and field-ownership rules from your mapping worksheet.
  2. Resolve person or company type, legal entity, business role, and any billing account before transactions.
  3. Test a normal update and one failed or repeated update in the supported direction. Keep both record IDs with the test results.

Expected result: Test an individual buyer, a company buyer, and one company with multiple billing relationships. Do not merge these into a single generic contact.

If it fails: Hold ambiguous customer matches for review and resolve customer type before retrying dependent records.

Sales order reporting workflow

Planning example. Stacksync support for the required connection and record operations needs a technical review.

Starting event: A change to the selected Proposed sales order table in Apache Cassandra (choose its name) or Sales orders record needs a defined result in the other system.

  1. Start with Apache Cassandra Proposed sales order table in Apache Cassandra (choose its name) and Plex ERP Sales orders. Use the record-matching and field-ownership rules from your mapping worksheet.
  2. Create or locate the customer and products first; resolve taxes, currency, and fulfillment references.
  3. Test a normal update and one failed or repeated update in the supported direction. Keep both record IDs with the test results.

Expected result: Test a multi-line order, a partial cancellation, and two partial shipments. Compare line totals as well as the header.

If it fails: Check for an existing destination order before retrying a timed-out create; reconcile line IDs to avoid duplicate fulfillment.

Supplier or vendor reporting workflow

Planning example. Stacksync support for the required connection and record operations needs a technical review.

Starting event: A change to the selected Proposed supplier or vendor table in Apache Cassandra (choose its name) or Suppliers record needs a defined result in the other system.

  1. Start with Apache Cassandra Proposed supplier or vendor table in Apache Cassandra (choose its name) and Plex ERP Suppliers. Use the record-matching and field-ownership rules from your mapping worksheet.
  2. Resolve business-unit and payment-term references before purchasing transactions.
  3. Test a normal update and one failed or repeated update in the supported direction. Keep both record IDs with the test results.

Expected result: Test a supplier shared across subsidiaries and an inactive supplier referenced by an open bill.

If it fails: Review rejected supplier changes before retrying dependent bills; do not reactivate a supplier merely to make a write pass.

Reconcile Plex ERP business records with Apache Cassandra

This is an evaluation scenario; connector and operation support require confirmation.

Starting event: A finance-owned record in Plex ERP needs operational visibility through a selected destination dataset.

  1. Select Inventory or Production jobs with the correct legal entity, period, and currency.
  2. Define a reporting relationship in Apache Cassandra; do not equate customer records, ledger accounts, and posted transactions.
  3. Decide whether the process only reports a financial state or requests an approved accounting action, and maintain a separate transaction ID for each action.

Expected result: Totals reconcile within the same entity/currency/window; a repeated handoff creates no duplicate financial transaction.

If it fails: Verify posting and settlement state before retrying. Use the approved adjustment path for already-posted transactions.

Initial load and acceptance testing

Keep both record IDs with the expected and actual result. Reconcile the same filters and time window in each system.

Proposed customer table in Apache Cassandra (choose its name) / Customers

Test case

Test an individual buyer, a company buyer, and one company with multiple billing relationships. Do not merge these into a single generic contact.

Expected result

The expected customer relationship is preserved with no duplicate action or unintended write.

Proposed sales order table in Apache Cassandra (choose its name) / Sales orders

Test case

Test a multi-line order, a partial cancellation, and two partial shipments. Compare line totals as well as the header.

Expected result

The expected sales order relationship is preserved with no duplicate action or unintended write.

Proposed supplier or vendor table in Apache Cassandra (choose its name) / Suppliers

Test case

Test a supplier shared across subsidiaries and an inactive supplier referenced by an open bill.

Expected result

The expected supplier or vendor relationship is preserved with no duplicate action or unintended write.

Proposed product or catalog item table in Apache Cassandra (choose its name) / Production jobs

Test case

Test two variants of one product, a changed SKU, and a price that applies to only one market or currency.

Expected result

The expected product or catalog item relationship is preserved with no duplicate action or unintended write.

Direction and permissions

Test case

Bring an example source record and the intended destination operation to the compatibility review. Confirm the supported route before granting write access.

Expected result

Only an approved, supported direction and permitted fields are written.

Freshness and reconciliation

Test case

Measure source and destination times for the selected records under normal load and a burst. Reconcile IDs and values using the same filters and cutoff.

Expected result

The process meets its agreed freshness target and reconciliation has no unexplained differences.

Failed updates, retries and recovery

Start with the failed record and the destination error, then inspect the source value, field requirements, and access.

Rejected or repeated customer change

Investigate

Inspect Apache Cassandra Proposed customer table in Apache Cassandra (choose its name) and Plex ERP Customers, their IDs, and the destination error.

Next action

Hold ambiguous customer matches for review and resolve customer type before retrying dependent records.

Rejected or repeated sales order change

Investigate

Inspect Apache Cassandra Proposed sales order table in Apache Cassandra (choose its name) and Plex ERP Sales orders, their IDs, and the destination error.

Next action

Check for an existing destination order before retrying a timed-out create; reconcile line IDs to avoid duplicate fulfillment.

Rejected or repeated supplier or vendor change

Investigate

Inspect Apache Cassandra Proposed supplier or vendor table in Apache Cassandra (choose its name) and Plex ERP Suppliers, their IDs, and the destination error.

Next action

Review rejected supplier changes before retrying dependent bills; do not reactivate a supplier merely to make a write pass.

A record type or update is unavailable

Investigate

Check the Apache Cassandra and Plex ERP connector guides, account permissions, and any operations marked On Request.

Next action

Ask the integration team to confirm a supported way to handle that record. Verify whether it needs connector configuration or a separate workflow step.

Source and destination disagree after a retry

Investigate

Compare current source values, destination validation, identity mappings, and any side effects already completed.

Next action

Stacksync issue retry reads the current source state. Decide the intended state before retrying or reverting; reconcile downstream effects separately.

Read the Stacksync issues dashboard guide for retry and revert behavior.
